Motor Description<br />
1.7 Cooling<br />
The different cooling types are defined in the <strong>Configuration</strong> <strong>Manual</strong> "General Section for<br />
<strong>Synchronous</strong> <strong>Motors</strong>"..<br />
Degree of protection IP54 (acc. to EN 60529).<br />
Degrees of protection IP64, IP65, IP67 and IP68 are not possible<br />
The hot discharged air may not be drawn-in again.<br />
Caution<br />
Forced ventilation cannot be used in the presence of flammable, corrosive, electrically<br />
conductive or explosive dust.<br />
Forced ventilation, SH 80 and SH 100<br />
Air flow direction from NDE to DE.<br />
If the air flow direction is reversed, this reduces the torque yield by approx. 20 %.<br />
Mechanical changes to the motor with respect to non-ventilated versions:<br />
• The power connector is about 12 mm higher.<br />
• A sheet metal envelope is located over the motor frame from the non-drive end side. The<br />
axial fan is mounted in this sheet metal envelope. There is a cut-out in the sheet metal<br />
envelope at the connector positions. This means that the motor is only partially cooled by<br />
the air flow (three-sided ventilation).<br />
• The motor dimensions can be taken from the dimension drawings.<br />
