Question

rotation of a fan a period change why​

Answer 1

Answer:

HERE IS UR ANS

1) Reduction in supply voltage

2) Reduction in supply frequency

3) Increased blade angle than designed value (mechanical loading

4) Wrong value of capacitor for phase splitting (or value changed with time) resulting in the optimum phase shift no more obtained for desired torque-speed curve.
