Cooling types
The different cooling types are defined in the Configuration Manual "General Section for
Synchronous Motors"..
1.7.2
Forced ventilation
Degree of protection IP54 (acc. to EN 60529).
e
Degrees of protection IP64, IP65, IP67 and IP68 are not possibl
The hot discharged air may not be drawn-in again.
Caution
Forced ventilation cannot be used in the presence of flammable, corrosive, electrically
conductive or explosive dust.
Forced ventilation, SH 80 and SH 100
Air flow direction from NDE to DE.
yield by approx. 20 %.
If the air flow direction is reversed, this reduces the torque
Mechanical changes to the motor with respect to non-ventilated 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.
