Section 5 : Choose the correct Answer
What happens if field winding of the synchronous motor is short circuited
First, starts as induction motor then run as synchronous motor
Not start
Motor will burn out
Run as induction motor
When the field of a synchronous motor is over excited, the power factor will De
Leading
Lagging
Zero
Unity
The synchronous motors are not self-starting because
The direction of torque on the rotor reverses after every half cycle
Slip is not present in synchronous machine
Starting winding not present in the synchronous machine
DC excitation used
