A d.c machime has a torque angle of 90 degree. When rotating the at 3000rpm with a field current of 1A, the generated voltage is 100v. When the two windings are connected to a a.c supply of 50hz, the field current is 0.1A, the armature current is 100A and the phase difference between them is 60 degree. calculate the average torque and maximum torque...has two few questions
