what will be happened when a single phase motor is supplied
by the dc supply
Answer Posted / santosh
torque in single phase induction motor is produced due to rotating magnetic field. if this motor is fed from dc, the rotating magnetic field is absent and the machine will not run.
also in the absence of reactance in DC, the machine will try to draw high current which will damage the winding.

Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?
