The different cooling types – non–ventilated and force ventilated have already
been defined in Chapter 2.1 General information (AL).
Degree of protection: IP 64 (acc. to DIN 40 050). IP 67 cannot be fulfilled. It is
not permissible that the hot discharged air is drawn–in again.
The separately–driven fan can be retrofitted, whereby you must taken into ac-
count the various measures required. Only an authorized workshop may retrofit
a fan onto motors, shaft height 100.
Due to the higher torques and therefore the higher phase currents, the motors
are in some cases, allocated larger power connectors.
Shaft heights 71, 100 and 132 differ as follows:
Shaft height 100 and 132: Airflow direction from the drive end to the non–
drive end
The air is drawn–in from the non–drive end through the corners of the ex-
truded enclosure by the mounted radial fan.
The modified dimensions should be taken from the dimension drawings.
Termination technology:
terminal boxes
Supply voltages:
3–ph. 400/460 V AC, 50/60 Hz
Max. current:
0.4 A
Weight of the fan assembly:
approx. 5.6 kg

Fan connection, shaft heights 100/132
Shaft height 71: Airflow direction from the non–drive end to the drive end
The available torque is reduced by approx. 20 % when reversing the airflow
direction.
Mechanical change of the motors over non–ventilated versions:
–
The power connector is positioned 12 mm higher.
–
A sheet steel envelope is placed over the motor enclosure from the non–
drive end; the axial fan is installed in this sheet metal envelope. Only
some air flows across the motor through the cut–out in the sheet steel at
the connectors (3–sided cooling).
–
The motor dimensions should be taken from the dimension drawings.
