Answer / surendra pratap

polly phase winding displace at certain angle mechanically
as well as electrically and carrying polly phase current.

Answer / skaz

Answer / arun k

it have two windings to produced rmf is 1.main winding and
2.auxiliary winding

Answer / ramasamyseenu

you can also include a delay in voltage by adding capacitor to it and which ultimately helps to produce rmf
