Protective grille

Casing

The fans are supplied in an all-welded metal casing with rolled flanges. All the casing components are powder coated for improved
protection against the environmental effects. The casing has special brackets for mounting the motor which also double as guides and
ensure even distribution of air across the impeller blades thereby improving the aerodynamic performance. The fans also have external
mounting brackets for ceiling or wall mounting. A terminal box is mated to the casing for quick and convenient electrical connections.

Protective grille

The grille prevents penetration of objects which may damage the impeller or the fan casing.

Silencers

Sound insulation is achieved by means of cylindrical silencers installed on both sides. The casing of the silencers is completely lined with
wear-resistant mineral wool and perforated sheet. The silencer 1 at the inlet is equipped with an aerodynamically optimized inlet nozzle,
and the silencer 2 at the outlet is equipped with louvre shutters.

Motor

The fans are driven by three-phase asynchronous electric motors with a square-cage rotor. The motor is installed inside the fan casing.
The impeller of the motor is equipped with an axial high-efficient and dynamically balanced impeller with blades of optimized shape
made of corrosion-resistant aluminium alloy.

MAKE SURE THAT THE FAN IMPELLER ROTATES IN THE DIRECTION MARKED BY THE

ARROW ON THE FAN CASING.

IF NECESSARY, CHANGE THE IMPELLER ROTATION DIRECTION BY ALTERING THE PHASE

SEQUENCE ON THE ELECTRIC MOTOR TERMINALS.

ASYNCHRONOUS ELECTRIC MOTOR STARTING METHODS

There are several methods for starting asynchronous squirrel-cage electric motors.
The most common methods are: direct-on-line (DOL), with a soft starter (SS) or with a frequency converter (FC).

Direct-on-line starting

In case of direct-on-line starting (i.e. by connecting the motor to the electric mains with a simple line contactor), the motor starting
time significantly increases due to high inertia of the impeller, which, in turn, results in high in-rush starting currents in the circuit. These
currents of long duration may cause voltage slumps (especially if the feed line section falls short of the requirements), which may affect
load operation.
The in-rush current consumed by an electric motor in case of DOL starting is 5-8 times larger than the rated value (or even 10-14 times
larger in some rare instances). It should be noted that the torque developed by the motor also significantly exceeds the rated value.
Upon energisation the motor operates as a transformer with a squirrel-cage secondary winding formed by the rotor cage with a very low
resistance.
The rotor develops high induced current causing a rush of current in the feed line.
The startup torque during starting averages 0.5-1.5 of the rated torque value.

www.blaubergventilatoren.de

Despite such advantages as simple construction, high startup current, quick start and low cost, direct-on-line systems are suitable only
in the following cases:

• the motor power is low compared to the mains power which limits the adverse effect of the rush of current

• the driven mechanism does not require gradual speed build-up or is equipped with a damping device to smooth out the inrush

• the high startup torque has no adverse effects on the operation of the driven mechanism

Soft start. SC starting.

A soft starter gradually increases the voltage supplied to the motor – from the initial to the rated value.
This starting system can be used to meet the following goals:

• limit the motor current

• regulate the torque

Regulation by limiting the current sets the maximum in-rush current equal to 300-400 % (or 250 % in some rare instances) of the rated
current and reduces torque characteristics. This type of regulation is especially suited for turbomachinery such as centrifugal pumps and
fans.
Regulation by variation of torque optimises the torque during startup and reduces in-rush current in the circuit. These conditions are
suitable for mechanisms with constant load resistance.
This type of soft starting may differ in the implementation pattern:

• motor start

• motor start and stop

• device bridging at the end of start sequence

• start and stop of several motors in stage circuits

Soft start. FC starting.

During the starting the FC raises the frequency from 0 Hz to the electrical mains frequency (50 or 60 Hz). As the frequency is increased
gradually, the motor can be assumed to operate at its rated speed for a given frequency value. Furthermore, on the assumption that the
motor runs at its rated speed the nominal torque should be immediately available whereas the current will be approximately equal to
the rated value.
This starting system is used for speed control and regulation and can be used in the following cases:

• start with high-inertia load

• start with high load and limited-capacity power supply source

• optimisation of electric power consumption depending on turbomachinery speed

The aforementioned starting system can be used for all types of mechanisms.

13

www.blaubergventilatoren.de

Problems associated with DOL starting

The problems caused by DOL starting may be divided into two groups:

1. An abrupt start causes mechanical shock, jolts in the mechanism, shock removal of free play etc.

2. A heavy start cannot be completed.

Let us review three variations of a heavy start:

1. The feed line performance is barely sufficient or insufficient to maintain the induced current.

Typical symptoms: Upon starting the circuit breakers at the system input are tripped; the lights, certain relays and contactors go off,
and the supply generator shuts down.
Solution: In the best-case scenario an SS device may help reduce the in-rush current to 250 % of the motor rated current. If this is
insufficient, an FC is necessary.

2. The motor cannot start the mechanism with DOL starting.

Typical symptoms: The motor fails to turn or “freezes” at certain speed which is maintained until actuation of the protection suite.
Solution: This problem may not be solved with an SS device. The motor develops insufficient shaft torque. However, this problem can

be addressed by using an FC, but each case may be different.

3. The motor spins up the mechanism with authority, but fails to reach the rated rotation speed.

Typical symptoms: The input automatic circuit breaker is tripped during spin-up. This often happens with heavy-weight fans with a
considerable rotation speed.
Solution: Such problems may be addressed with an SS device, but not with 100 % certainty. The closer the motor speed to the rated
value during the actuation of the protective equipment, the higher the chances of success. The use of an FC in this case helps solve the
problem fundamentally.

Axis-Jet

Standard switching equipment (automatic circuit breakers, contactors and motor starters) is not designed to withstand
prolonged overloads normally causing the fan to shut down automatically DOL starting that continues for a long period of
time.
Using switching equipment with a higher maximum current rating renders the electric motor protection system less sensitive.
As a result the switching equipment will not be able to detect motor overload in time due to a high current sensing threshold.
Such problems as mentioned above can only be addressed by utilizing a soft starter or a frequency converter to start the fan.

COMMISSIONING

THE ORGANISATION RESPONSIBLE FOR THE COMMISSIONING SHALL BE RESPONSIBLE

FOR PROPER MOTOR PHASING AND STARTING PATTERN SELECTION.

DURING STARTING THE INRUSH CURRENTS OF THE FAN MAY SEVERAL TIMES EXCEED

THE RATED VALUES.

SEE “ASYNCHRONOUS ELECTRIC MOTOR STARTING METHODS” IN THE “CONNECTION

TO POWER MAINS” SECTION

• After fan starting make sure that the motor rotates properly without undue vibration and abnormal noise.

• Make sure that the fan impeller rotates in the direction marked by the arrow on the fan casing. If necessary, change the impeller
rotation direction by changing the phase sequence on the electric motor terminals.

• Make sure that the fan energy consumption complies with the value given on the equipment nameplate and check the motor for
overheating.

• The phase current should be checked once the fan reaches the rated operating conditions.

• Do not switch the fan on and off several times without pauses as this may result in damage to the winding or insulation due to
overheating.
