A 6-pole and three-phase induction motor has synchronous speed of (1000) RPM.

a) Find the no-load and full-load operating speed of motor for the cases given,

1. 2.5Hz electrical frequency of rotor for no-load condition.

2. 6.3Hz electrical frequency of rotor for full-load condition.

b) Find the speed regulation of motor by using parameters found above.

c) Determine the electrical frequency of rotor under full-load condition so that speed regulation would be equal to 5%? (Electrical frequency of rotor for no-load condition is still 2.5Hz.)
