Switchable pole motors
NORD switchable pole motors enable operation with two or more fixed speeds. Squirrel cage motors with this design provide an economical alternative for applications in which continuous speed control with inverters is not required.
They are available in the following versions: 4-2-pole, 8-2-pole and 8-4-pole. Switchable pole motors have the advantage that they only need a single winding for operation at two speeds. NORD supplies these with the following options (selection):
- Brake (BRE+), Double brake (DBR+), External fan (F), Incremental encoder (IG)
- Motor protection: Temperature sensor (TF), Thermostat (TW), Anti-condensation heater (SH)
- Motor connection: Motor plug connection (MS)
