Question

The mmf of the damper windings depends on the pole pitch value.

(a) true

(b) false

I had been asked this question by my college director while I was bunking the class.

My query is from Design of Rotor in section Design of Synchronous Machines of Design of Electrical Machines

Answer 1

Right choice is (a) true

To explain I would say: The mmf of the damper windings depends on the pole pitch value. The value for the mmf of the damper windings = 0.143 * specific electric loading * pole pitch.
