The torque of the motor is equal to zero. The tightening force between the rotary field pole and the rotor pole may be at the maximum, but no effective moment arm is produced. ST-87x /ST-88x Conductix-Wampfler Automation GmbH / 04/2023...
Page 137 If the frequency converter can supply a higher voltage, the speed can be increased further (7). This leads to a higher power at a constant torque. If the voltage has reached an upper limit, the motor crosses over into the field-weakening range (88). ST-87x /ST-88x Conductix-Wampfler Automation GmbH / 04/2023...
