Question

State true or false for the following: A. Speed regulation of a synchronous motor is 100% B. Synchronous motor is self-starting motor if the field winding is placed on the

stator and armature winding on the rotor. C. Induction motor can be regarded as the rotating transformer with secondary frequency same as the primary frequency. D. Smallest voltage is induced in the rotor if it rotates at synchronous speed. E. The full-load torque of the induction motor is slightly larger than its starting torque. F. A synchronous motor can be operated under-excited to supply reactive power Q for a power system. G. Machine will remain in synchronism when pull-out torque is exceeded. H. Converted power will be equal to the power available at the air-gap when induction motor is just starting.
