AC SINGLE PHASE MOTOR - Quiz

1) What is the function of centrifugal switch used in capacitor start, capacitor run induction motor?

Disconnect the running winding after reached 75% to 80% speed Disconnect the starting winding after reached 75% to 80% speed Disconnect the starting capacitor after reached 75% to 80% speed Disconnect the starting and running winding after reached 75% to 80% speed

2) Which type of single phase motor is having very high starting torque than any other type of single phase motor?

Universal motor Reluctance motor Repulsion start induction run motor Capacitor start induction run motor

3) Where the capacitor is connected in a single phase permanent capacitor motor?

In series with starting winding In series with running winding In parallel with starting winding In parallel with running winding

4) Which motor is used in table fan?

Universal motor Shaded pole motor Eddy current motor Permanent capacitor motor

5) What is the effect, if coil group connection is wrongly connected in a single phase motor rewinding?

Motor runs slowly Motor will not run Motor runs in very high speed Motor runs and takes more current at no load
