Rotation speed

Rotation speed If the motor shaft should rotate at the same speed as the magnetic field, the induced current in the rotor would at the same time be zero. However, due to losses in, for example the bearings, this is impossible and the speed is always approx. 1-5% lower than the magnetic field's synchronous speed (slip). Applicable for this synchronous speed is:
