The motors are asynchronous squirrel-cage motors with compact dimensions in fin-cooled design with a separately driven fan. As these motors are forced-ventilated, no derating or only relatively minor derating (depending on their speed range) is required for operation at constant load torque and with wide speed ranges. The motors are designed for converter-fed operation with the SINAMICS and SIMOVERT MASTERDRIVES drive system.
- Converter-fed operation
- Cooling method: IC416, forced-air cooling
- Degree of protection: IP55
- Housing: Cast iron
For further information and details, see the sections “Orientation” and "Technical data".
The motors are available with standard insulation for voltages ?500 V or with special insulation for 690 V.
Guide values for the maximum load torques at various speeds can be obtained from the diagrams below.
