The number of the pole in Small DC Motor Up to 5 H.P are
Right Answer is:
2 poles
SOLUTION
- Small H.P motors require only 2 poles because the number of poles is inversely proportional to the speed therefore 2 pole motor runs at high speed than 4 pole motor.
- Two pole motor has better efficiency.
- Two pole motor has better rpm and noise performance.
