Description : What is back EMF of synchronous motor?
Description : What is the back EMF of a dc motor?
Description : The back emf of synchronous motor depends on?
Answer : The back emf of synchronous motor depends on load angle.
Answer : The armature may burn if the back e.m.f. of a D.C. motor vanishes suddenly.
Answer : The mechanical power developed by a shunt motor will be maximum when the ratio of back e.m.f. to applied voltage is 0.5.
