what happens when a DC supply is given to AC motor?
Answer Posted / bikash chandra pal
Earlier reply is OK, some more elaboration given below
No rotating magnetic field is generated and hence the motor
will not rotate,
No back EMF will be generated,
reactance(XL)will not come effect as frequency is "ZERO",
Rotor impedance will be remain isolated from equivalant ckt
of stator.
Only resistance of stator ckt(which is very low) will be
there. Hence stator current will be very high,Motor will
burn.
