Electrical Engineering

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

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

1. 2.5Hz electrical frequency of rotor for no-loadcondition.

2. 6.3Hz electrical frequency of rotor for full-loadcondition.

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

c) Determine the electrical frequency of rotor under full-loadcondition so that speed regulation would be equal to 5%?(Electrical frequency of rotor for no-load condition is still2.5Hz.)
