Answer to Question #187664 in Engineering for Alock kumar

Question

Describe slip and voltages regulation.

Answer 1

The difference between the synchronous speed of the electric motor magnetic field, and the shaft rotating speed is slip - measured in RPM or frequency.

Slip increases with increasing load - providing a greater torque.

When a motor starts to rotate the slip is 100 % and the motor current is at maximum. Slip and motor current are reduced when the rotor begin turning.
