i think a synchronous motor is based on the same principle
as separetely excited dc motor,the only difference is that
its rotor or magnetic field rotates by the speed of 120f/p
with the help of a pony motor. in influence of the magnetic
field of rotor, stator or shaft rotates or comes in
working.also an asynchronous motor is nothing but an
induction generator but working in negative slip region.

Calculate torque developed by the 3-phase, 5 H.P., 4 pole induction motor runs at 1500 rpm A 23 N-m B 21 N-m C 10 N-m D 0 N-m

some practicle study shows that the reactive power at the receiving end is not equal to the reactive power at the sending end.But according to theory the reactive power is exchanged by different parts of the network – capacitors and reactors permanently, but is never consumed or produced. Then Where that reacrtive power loss occuring?is there any formula to calculate reactive power loss?
