Consider the following statements about damper windings used to start a synchronous motor: a) When a motor is overloaded it does not stop. b) A synchronous motor is made self-starting by providing a damper winding. c) Damper windings consist of short-circuited copper bars embedded in the face of the field poles. d) Since damper winding resistance is high, it takes a small current from the supply mains. Choose the correct combination of statements.
