Danger !

General danger (Danger of persons and/or material)

Use in hazardous areas is prohibited.

Dangerous electrical voltage.

High temperature.

Assembly or dismantling using hammers or other striking tools is prohibited.

Note: Use raw material for recycling.

2. General safety notes

First read, then act !

3.1 Unpacking

¯ Take drive components out of the packing

and check for transport damages.

¯ Check if the shipment is complete.

3.2 Transport within the site of installation

¯ Tranport motors only with sufficiently strong

transportation tools or hoists. Ensure safe fixing.

Some of the motors are equipped with eyebolts for a safe fixing at the hoists (for weights see chapter 4.5).

¯ Transport motors vibration--free

¯ Avoid strong shocks and impacts

3.3 Conditions of storage

¯ Location of storage:

-- v i b r a t i o n -- f r e e If there is a risk of vibration, it is recommended to rotate the rotor in its bearings once a week.

-- dry without aggressive media

-- n o d u s t

-- no fast temperature changes

¯ Corrosion:

3.4

2.1 Users

Assembly, commissioning, operation, and maintenance only by specialists or skilled personnel.

2.2 Safety notes

n Read operating instructions before

asembly, commissioning, operation, and maintenance.

n Observe safety notes and warning symbols

in the individual chapters.

n Observe regulations for safety and

prevention of accidents.

n Do not operate in hazardous areas !

n Only intended use is permissible.

n For non--intended use and non--authorized

modifications, the product liability and warranty are invalid.

-- steel parts are protected against corrosion by the factory. Do not remove this protection, check in intervals of approx. three months and renew, if necessary.

In case of intermediate storage > 3 months ¯ Collector:

-- take off carbon brushes from the collector surface

-- protect collector by a piece of paper around the running surface.

3.4 Waste disposal of the packing material

n Packing material can be recycled.

4.1 Function description

The motors of the MGXRK, MGXQU and MGXQK series are separately excited DC shunt motors. The motors of the MGXRK series are surface--cooled in IP54 enclosure and have a round, ribbed housing. The motors of the MGXQU and MGXQK series have a square cross--section, are designed in IP23S enclosure and internally ventilated. The motors have fully--laminated stators and are externally cooled by axially or radially mounted blowers in their standard design (type GF...). With reduced power, the motors are also supplied with speed--dependent self--ventilation (type GE...) and without ventilation in self--cooled design (type GS...).

4.2.1 Other areas of application

¯ For other areas of application a power or

torque reduction is required using the factors of the following table.

The permissible continuous power is calculated from:

P’ = kJ¡ k

¡ P

with Pdbeing the permissible continuous torque under normal conditions. The torque can be calculated accordingly:

M’ = kJ¡ k

being the permissible continuous torque

¡ Md.

under normal conditions.

4.2 Area of application

n Do not use in hazardous areas !

n Fire risk !

Avoid contact with inflammable material !

¯ Ambient temperature must be up to

+40 5C, higher ambient temperature require a power reduction.

¯ Installation height up to 1000 m above sea

level, installation above 1000 m above sea level requires a power reduction.

¯ Observe temperature class F (155 5C)

according to DIN--IEC 34 / VDE 0530. If the limit temperature is exceeded, the insulation is weakened and damaged.

¯ Enclosure to DIN--IEC 34 is IP54 or IP23S.

The actual enclosure can be obtained from the nameplate (see chapter 4.4.)

¯ No tropical insulation.

¯ If the actual form factor FF* ≥1.05, a power

reduction or torque reduction is also required.

The permissible continuous load is calculated from:

P’= ( 1.05 / F

*)¡ P

The torque is calculated as follows:

M’ = ( 1.05 / F

*) ¡ M

The form factor can be improved, among others, by using armature chokes. Armature chokes which are suitable for Lenze controllers can be obtained from the technical descriptions of the controllers or from your nearest Lenze representative.

The motors can be mounted in any mounting position. Vertical arrangements according to DIN--IEC 34 part 7 are possible.
