Cooling methods

The different cooling methods are defined in the Configuration Manual "General Section for
Synchronous Motors".
1.6.2

Forced ventilation

Degree of protection IP54 (acc. to EN 60529).
Degrees of protection IP67 and IP68 are not possible.
The hot discharged air may not be drawn in again.
Caution
Forced ventilation cannot be used in the presence of flammable, corrosive, electrically con-
ductive or explosive dust.
Forced ventilation, SH 80 and SH 100
Air flow direction from NDE to DE.
If the air flow direction is reversed, this reduces the torque yield by approx. 20 %.
Mechanical changes to the motor with respect to naturally cooled versions:
• The power connector is about 12 mm higher.
• A sheet metal envelope is located over the motor frame from the non-drive end side. The
axial fan is mounted in this sheet metal envelope. There is a cut-out in the sheet metal
envelope at the connector positions. This means that the motor is only partially cooled by
the air flow (three-sided ventilation).
• The motor dimensions can be taken from the dimension drawings.
