HIGH-FREQUENCY TECHNOLOGY

All of the air tools listed in this catalogue meet the following standards or norm documents EN 792, EN 50144, in accordance with the regulations of Directives 89/392/EEC.

Conformity

Better performance through higher frequency

Because their carbon brushes are subject to wear, universal motors of conventional power tools are unable to satisfy these requirements.On the other hand, the brushless asynchronous motor is ideally suited. The current frequency it is supplied with determines its rotational speed, which, in turn, determines the output that can be achieved.A higher frequency therefore means a higher speed and a higher output.

High power at a constant speed

In continuous operation at 300 Hz, Bosch high-frequency tools have a power output of up to 400 Watts per kg machine weight. In the short term, peak perfor mances of up to

2.5 times this value are possible. The speed remains almost constant – irrespective of whether the tool is being operated at idle or full load.

Unique economy

A further argument in favour of high-frequency tools: their economy. Their efficiency and thus their power consumption means that they have unrivalled economy. Their long service life and low maintenance requirementsand power consumption offer an economic solution for every type of application.

Distinct environmental consciousness

Environmental thinking plays a central role in all Bosch products: from the initial development of the idea and energy saving products, to environmentally friendly packaging and disposal. If a Bosch high-frequency tool is irreparably damaged, B osch will take back the old tool.They are collected centrally in the service centre and passed on for careful recycling.

Special power saving measures

Bosch is also innovative in the area of power saving and places an emphasis on future-oriented technology: The heat recovery system in the Murrhard plant,for example, produces savings of over half a million litres of heating oil a year.

Information from the Internet

Bosch now offers users and others interested in industrial tools all current product information on the Internet.Here you will find a free online catalogue illustrating in text and pictures all the common cordless, air and hig h-frequency tools for industrial use. More information on Pag e 4.

In spite of increasing automation in industrial production, the use of hand-held tools has advantages in many work operations. These tools must fulfil several requirements: robustness, powerful and a long service life, but they must also be easy to manage with high operating comfort.

Selection of the rig ht drill depends mainly on the following two points:

drill bit diameter and the recommended cutting speed

of the material to be processed. In the table, the preferred bit sizes are assigned to the individual drill types for some common materials. The table shows the drill bit sizes with which the individual types are able to reach the recommended cutting speeds. However, the feed of hand-held tools cannot be increased arbitrarily with increasing bit diameter, since the necessary feed force can no longer be applied. For this reason, the maximum bit diameters for steel and aluminium are allocated to the individual types on page 6. These maximum diameters were determined by tests,unlike the information in the table. In order to achieve a sufficient cutting speed with normal hand pressure, some materials should be predrilled for the following bit diameters:

steel upto 600 N/mm

as of 8 mm

steel upto 600 N/mm

as of 6 mm

cast iron up to 180 N/mm

as of 10 mm cast iron up to 300 N/mm

as of

8 mm

Note: If only one bit diameter is specified in the table, it refers to the lower limit of the recommended cutting speed. If nothing is specified, the recommended bit diameter is outside the clamping range of the standard chuck.

Please observe manufacturer’s information regarding grinding material.

In order to select the correct grinding machine, you must take the area of application and specific circumstances into consideration. That is to say, selection of a gr inding point predetermines selection of the suitable g rinder. In both tables – one for straight grinders and one for angle grinders – the machines have been ordered to the grinding tasks or grinding points for which they are appropriate. The more powerful the machine, the larger the amount of material that is removed.Because of the great variety in individual working conditions and spatial considerations, these recommendations can, however, only serve as guidelines. In any case,when selecting a grinder,you should take other product features into consideration in addition to performance.

Tightening torque

Guideline values for maximum bolt/screw tightening torques in Nm. Assumed friction below head m

ges.

= 0.12, calculated from the stressed cross sections: yield point usage 90 %. Valid for shaft screws with standard metric thread as per DIN 13, BL 13; heads as per DIN 931, 933.

When you select a screwdriver,you must consider not only the required torque – as a function of the pretensioning force required from the bolted connection – but also the torque accuracy as a function of the bolting event. This information has been compiled in tables 1 and 2 in order to facilitate the selection from among the various bolting systems. The fixed torque values provided apply to “hard”bolted connections. The maximum values are lower for “soft”bolted connections (e.g. spring washers, rubber washers, etc.)

Screwdrivers with adjustable cut-off clutch

For screw connections with high torque accuracy Torque upper range limited by reaction torques Further advantages: low noise,low wear, long service life,

the user has no influence on the torque

Impact Wrenches

For large screw / bolt diameters with high torque Virtually free of reaction torque,therefore no upward limitation

Torque is a decisive parameter for controlling the pretension force applied. The table provides an overview of the recommended torques for common bolt and nut sizes.The recommended maximum torques apply to untreated,oil-lubricated screws (coefficient of friction =

0.125). The torques correspond to approx.62% of the yield point.

Torque accuracy depending on screwdriver system and screwdriving type

The torque that can be achieved for a screw connection depends on the type of screwdriving / bolting situation. To achieve a balanced basis for assessment, all data on screwdrivers is based on unbending,or “hard” screw connections (30° angle of rotation).In the case of flexible or “soft”screw connections,achievable values are,in part, considerably belowthe nominal values. Furthermore , torq ue v a r i a n ce increases. Due to the wide varie ty of possibilities, specifications with absolute values are not possible. If in doubt, use a trial and error system. The table offers an overview of the advantages and achievable torque accuracy of the individual screwdriver s ystems with various characteristic screwdriving applications.

A real concept: High-frequency Tools

How a good idea was consistently further developed: The designation ’high-frequency tools’came to be known through the market launch of the tools and was given to those powerful high-frequency tools with asynchronous motors,operated with three-phase current at an increased frequency of 200 or 300 Hz. In a physical sense,there is no real connection between these tools and genuine high-frequency technology,but they still came to be known under this name.

The operating frequency determines the performance

In hand tools, rotar y current at increased frequency of 200 or 300 Hz combines high electrical performance with minimal motor weight. As the frequency of the rotary current increases, there is a proportional increase in motor speed and thus in the performance of asynchronic motors. This is limited by the maximum admissible circumference velocity (operating rotational speed) of the tools.An optimum performance/weight ratio is achieved by high-frequency tools operating at a frequency of 200 to 300 Hz

(Fig. 1). Large differences between motor rotational speed and operating rotational speed require larger gears. This means that weight savings from the rotary current drive are negated by the increased weight from the stepdown gearing. High-frequency installations using exclusively grinders should be operated at 300 Hz. Using rotar y current at increased frequency optimally fulfils the demand for light yet high-performance hand tools.

Fig. 1 The graph shows the dependence of motor and gearing weight on frequency at constant motor performance and rated rotational speed.

300 Hz yields an optimum performance/weight ratio.

ROBUST TECHNOLOGY FOR LONG-TERM HEAVY-DUTY USE.

A high-frequency motor is a three-phase current motor with a short-circuit rotor. Its stator and rotor consist of a laminated sheet-metal bundle. If the stator winding of the motor is connected to the three-phase current supply, a magnetic field is created (rotary field), which runs through the motor due the arrangement of the winding and which is dependent on number of pole pairs and the frequency.

An operating frequency of 300 Hz is to be recommended for a highfrequency electric tool installation. The higher motor rotational speed at 300 Hz is particularly advantageous at today's circumference velocities for grinders. The increased motor rotational speed results in higher machine performance without an increase in weight. In so far as possible, 135 V current should be selected for 200 Hz and 200 V for 300 Hz, regardless of country.

The secondary power output of the frequency converter or its size is calculated as follows: The hig hfrequency electric tools to be used are grouped according to motor size and number so that their rated current consumption can be added together. Multiplying the sum of the rated cur rent values by the operating voltage and the factor ö3 results in a calculation for the entire apparent power consumption for the tools. The formula is:

S =

3 · U · I = 1.73 · U · I

Once the apparent power value has been calculated in this way, it must still be multiplied by the simultaneity factor G in order to obtain the secondary power output of the converter.The simultaneity factor G takes into account the degree of use of all of the tools–since the tools are generally not all used at the same time.

E LE CTRI CAL OP E RATI N G VALUE S.

For the simultaneity factor G, we have the following experiential values: automobile body manufacture 0.45 motor manufacture 0.30 appliance manufacture 0.40 tool and form manufacture 0.25 steel manufacture 0.50 foundry work 0.60

In planning for a high-frequency electric tool installation, you must always take into account the need for a certain amount of reser ve power in the frequency converter. Particularly for small installations, you must bear in mind that the power output must be at least twice the rated power consumption of the most powerful highfrequency electric tool to be connected.This ensures that the tools will start without trouble. In the event of short-term overload, the voltage drop at the frequency converter will not be too large.

A magnetic field forms in a threephase current motor, which circulates through the motor. This is called a rotary field and is dependent on the number of pole pairs and frequency. When the smallest possible number of pole pairs is used, at a frequency of 50 Hz, for example, a rotar y field or rotor speed of 3000 rpm results; at a frequency of 200 Hz: 12000 r pm and at 300 Hz: 18000 rpm.

Due to the short distance between bearings and the stationary stator coil, the motor is both mechanically and electrically very reliable. It is distinguished by steady, lowvibration operation. Speed drop is only approx.5% at rated load, and peak performance is around 21/2 times the rated performance. Short-term overloads are possible as long as they do not result in the admissible coil temperature being exceeded.Since the objective in hand tools is to make them as light as possible with the highest possible performance, Bosch has decided in favour of“dust protection with direct cooling" for its high-frequency motors (Fig. 2). This combines the advantages of both encapsulated and open construction. The flow of cooling air ensures good heat dissipation; at the same time, dust and dirt are prevented from penetrating into the rotating system.

The design concept underlying Bosch high-frequency electric tools offers the user the following advantages:

Optimum performance in

a light-weight tool

During extended operation, Bosch high-frequency elect ric tools achieve a performance level of up to 400 watts per kilogram machine weight. Shor t-term peak performance levels reach 2 1/2 times normal operating perfor mance output.These high reserves mean a decisive improvement in work performance.

Constant rotational speed

under load

The speed drop for Bosch highfrequency electric tools is only 3 – 5% at rated load (Fig. 2). This ensures that recommended average speeds can be used to full advantage during grinding and drilling. The constant average speed means that the tools can be employed more efficiently and

Sample calculation for a high-frequency electric tool installation

A foundry wishes to introduce 3 high-frequency 0 602 332 034 angle grinders with 230 mm diameter cutting discs and 3 highfrequency 0 602 242 134 straight grinders with 100 mm diameter grinding discs.

Calculation: (Refer to pages 24 – 25 and 30– 31 for current and voltage values)

3 grinders, motor size 88 3· 10 A = 30.0A

3 girnders, motor size 85 3· 6.4 A = 19.2 A

Total: 49.2A

This yields the apparent power:

S = 1.73 · U · 1

= 1.73 · 200 V · 49.2 A = approx. 17023 VA = approx. 17 kVA

This value must still be multiplied by the simultaneity factor, G = 0.6 for foundries:

Converter apparent power = S · G = 17 kVA · 0.60 = 10.2 kVA

In this case, a converter with 11 kVA secondary power is selected so that there are additional power reser ves of approx. 10%.

DESIGNING AN INSTALLATION FOR HIGH-FREQUENCY ELECTRIC TOOLS.

Frequency converter with synchronic generator

The best solution, technically speaking, in selecting frequency converters is the combination of asynchronic motors with synchronic generators. The converters are single-wave aggregates with an asynchronic motor as drive motor and a brushless innerpole-generator with built-in current generator. The voltage difference between idling and operation under full load is only approx.3% for small transformers at cos f 0.6 – 0.9, for large converters,approx. 4%. Synchronic converters are not affected by voltage fluctuations in the primary rotary cur rent mains and, in addition, safeguarded against short circuiting. Assimilation to the rated voltage can be effected by means of a potentiometer. Moreover, the converters are maintenance-free for 20,000 machine hours. Secondary frequency is calculated according to the following formula:

2=f1·p2/p1

f1= primary frequency of

rotary current mains

f2= secondary frequency for

high-frequency electric tools

p1= pole pair count of the

drive motor

p2= pole pair count of the

generator

Frequency converters with a power output in excess of 4 kVA should generally not be switched into the mains direct but con-

nected by means of star delta switches. When they are switched in directly, a short-term current surge occurs. This surge could overload the lead wires on converters over 4 kVA and trigger the serial fuse. When a star delta switch is used, the current surge is reduced since current flow over the star switch is reduced to one third of what it would be with direct switching.

When a star delta switch is used, the coil of the drive motor is switched from the star (switch-on process) to the delta (operating position). It is imperative that a frequency converter that is to be operated on a 400 V mains line with a star delta switch is laid out for 400 V in the delta.If a converter of this kind is laid out for only 230 V in the delta,it can only be switched in to the 400 V mains directly over the star, that is to say, without star delta switching. When laying out a new installation, it is very important to take this into consideration.

Parallel operation of frequency converters

In order to increase the economics of the entire installation and to equalize load peaks, frequency converters can be switched in parallel. This results in optimal assimilation to the equipment being used. When frequency converters are linked to synchronic generators, no particular preparations are required to operate equipment in parallel even when power output levels differ.

Compensating for reactive current

Every inductive consumer is lumbered with a reactive current that performs no effective work, but only loads the electrical wiring. Frequency converters and high-frequency electric tools are also inductive consumers.

Compensation for reactive current on the secondary side of the converter requires considerable expenditure since each tool must be compensated separately. Depending on the number and the performance level of the individual high-frequency electric tools, a total output factor cos f of 0.5 to 0.85 is to be reckoned with. On the primary side of the frequency converter, the output factor cos f can be significantly improved if the magnetizing current from the drive motor and generator are compensated. Switching in correspondingly rated capacitors makes it possible to counteract the primary side reactance output of the converter almost entirely when idling and to compensate it under load to such an extent as to yield an output factor larger than cos

f = 0.9.

E LE CTRI CAL SAFETY.

For high-frequency electric tools, electrical safety is assured by the protective conductor as per EN 50144 based on protection class I. When the secondary coil of the converter is switched in the star,the star point or neutral point is extended outwards.This neutral point is earthed (earthing resistance RBŒ2 ohms) and connected to the metal housing of the electr ic tools by way of the protective conductors so that, at an operating voltage of 265 V, the dangerous voltage between phase and earth is only

265 V

1.73

= 153 V

At operating voltages of 135 V or 72 V, on the other hand, the dangerous voltage is only

135 V

1.73

= 78 V or

72 V

1.73

= 42 V

The effectiveness of the protective earthing is assured by using correspondingly robust plug fixtures of faultless electr ical construction

together with suitably resistant cables. Careful maintenance is equally important. The electric tool itself must, in its construction design, be capable of satisfy ing the stringent demands of industrial manufacture. Under normal circumstances, the description provided above,e.g. the protection measure “Earthing" as per VDE 0100 – 10 N is adhered to.

The possible protective measures may be classified and subdivided as follows:

Fig. 4

Fig. 5

1.0 protective measures without switching device

1.1 protective insulation (VDE 0100 – § 7 N)

1.2 low voltage,42 V (VDE 0100 – § 8 N)

1.3 protective separation (VDE 0100 – § 14 N)

2.0 protective measures with switching device

2.1 protective earthing (VDE 0100 – § 9 N)

2.2 reduction to zero voltage (VDE 0100 – § 10 N)

In cases 2.1 and 2.2, sw itch-off is effected by fuses or corresponding thermo-magnetically triggered station circuit breakers.

The greatest possible degree of protection is reached by using fault current (FI) circuit breakers in addition.

Protective insulation as per 1.1 is not applied to high-frequency electric tools. Low voltage as per 1.2 finds application only in special cases in which, due to existing regulations, it cannot be avoided.Because of the high currents involved, this measure is very problematic with respect to cable cross-section, switches, plugs etc. when applied to the transmission of large outputs. Small screw drivers comprise an exception.In this case, one is better off using protective separation as per 1.3, according to which every tool must have its own separator-converter. Protective separation should be restricted to circumstances in which it is absolutely necessary.

Here we wish to focus on the protective measure “reduction to zero voltage as per 2.2" since it finds application primarily with high-frequency electric tools.The voltage reduction should continuously prevent excessive contact potential on installation parts that do not belong to the operating circuit (see Fig. 5). It requires direct earthing of a midpoint or star point conductor and is effected by connecting the installation parts that are to be protected either to the neutral conductor or to a special protective

conductor that is in turn connected to the neutral conductor.

The protective measure “reduction to zero voltage" thus switches off defective installation parts since the inline fuse directly before the defective location is activated.

If the fuse is really to be activated, certain voltage reduction conditions as per VDE 0100 – § 10 N must be complied with. The most important voltage reduction requirement: The cross-section of the leads from the power

The distribution network must not have any connection with the existing 50 Hz supply mains. For this reason,special CEE plugged connections as per DIN 49462/63 and DIN 49465 are prescribed for frequencies between 100 and 300 Hz. The housings for the plug, coupling box and wall socket are all green. The different shape of these plugged connections prevents existing 50 Hz plug units from being combined with either the plugs or the coupling boxes. Depending on practical requirements, either movable or fixed leads may be used for the distribution network between the

frequency converter and the individual high-frequency electric tools. The transmission of high power levels at low voltage is uneconomical in broadly distributed installations. There will either be high installation costs due to the large lead cross-sections required or else transformers will be needed to reduce the higher voltage at the place of tool operation. Presupposing a constant level of power transmission, predefined voltage drop and equal lead length, the lead cross-section is inversely proportional to the square of the voltage, i.e. half the

voltage will require a lead crosssection that is four times larger. The required distribution network cross-section can easily be determined by refering to Figs. 9 to 12. The admissible voltage drop of 5% from ohmic resistance,the admissible temperature increase and the voltage drop from inductive resistance are all taken into account in calculating lead crosssections. The illustrations are to be read as follows:

§ 9 N will at least be activated whenever a complete short circuit between an outer conductor and the neutral conductor occurs at any point in the circuitry.

One can also use fault current circuit breakers in addition,as shown in Fig. 6 (illustrated, for the sake of simplicity,for single-phase current). The FI circuit breaker receives its impulse from a current transformer through which all of the lead wires inclusive neutral con

ductor pass.

The secondary coil of

current for the relay

coil of the FI circuit breaker. The w ires surrounded by the current transformer generate an alternating magnetic field in the core of the transformer if all of the currents do not neutralize each other in sum total (Fig. 7). During faultfree condition of the FI circuit breaker, the current flowing to the consumer is of exactly the same magnitude as that flowing back from it.Thus the two currents neutralize each other.There is no resulting induction onto the secondary coil of the current transformer,and the relay coil of the FI circuit breaker remains currentless (Fig.6).

If there is a fault condition at the FI circuit breaker, a fault current flows off through the earth; the currents in the current transformer are no longer all mutually neutralized and induction results. Voltage is induced on the secondary side of the transformer.

The relay coil in the FI circuit breaker is activated (Fig.7). 45 mA FI circuit breakers are available for 265 V/200 Hz rotary current. FI circuit breakers for rotary current at other voltage and frequency levels must be specially requested from appropriate manufacturers.

A schematic representation of an FI circuit breaker is provided in Fig. 8. In order to accommodate the regulations and specific conditions in other countries, Bosch offers high-frequency electric tools for various operating

voltages (265 V, 135 V, 72 V, 42 V at 200 Hz; 200 V, 72 V, 42 V at 300 Hz). At the lower voltages, however, only a few high-frequency electric tools should be used in close proximity to the associated frequency converter. This is because the currents arising at high power levels and low voltage require cable cross-sections that would be too large.

Move horizontally from the left or the right, depending on the type of cur rent, with the value of the power to be transmitted until the row intersects with the column for the voltage. Next, move vertically downwards until you intersect with the line for the lead length (simple length), then move horizontally again to the left or the right.

The cross-section calculated in Fig. 9 is now tested for temperature rise. Move horizontally from the left with the value of the power to be transmitted until you intersect with the column for the voltage. Next, move vertically downwards until you intersect with the line for the output factor cos

f; finally,move horizontally to the right to find the crosssection for the type of lead you are using.

Cable cross-section as a function of frequency and inductive resistance

If the cross-section for rotary current resulting from Figs. 9 and 10 e x c e eds 10 mm

, you must then apply the precise calculated value to Fig. 10 in order to take the inductive voltage drop into account. Next, move vertically upwards from the horizontal

base line until you intersect with the frequency curve. T hen move horizontally to the left or right. The larger of the calculated values for the cable cross-section is decisive in determining the lead.

Inductive resistance is significant for large cross-sections. These, in turn, are necessary at low voltages or high frequencies. Calculation of the cur ve in Fig. 11 was based on an assumed output factor cos

f of 0.7 for the

consumer.

For single phase alternating current installations with an output factor cos

f = 1, inductive resistance can be ignored even for large cable cross-sections.
