Answer Posted / pavan
it can be used to generate ac current if the frequency of
the ac voltage supplied to the rotor and the frequency of
the rotation of the motor are different. but i am not sure
if the generated power will have only a single harmonic.

generally in LT and MV motors we are using 3.5Coresx16,25,35,50 etc cable for supply.although motors is earthed at two point and having all protection.then why we are using that 1/2 core for earthing the motors.while in HT cable we are using only 3core cable for motor supply.generally lt and mv motors are delta connected and ht motors having star connection.whethere it is having any relation with winding connection( star or delta).all motors i am talking about are dol only.can anybody solve my confusion.thanks...
