Why induction
motor can not be
operated at
synchronous
speed?? what
would happen if
it is operated
at synchronous
speed??
Answer Posted / pillay
induction motor CAN run at syn speed but due
to mechanical strain there is bound to be a
slip .The higher the slip higher the current
consumed thus it cannot be operated at a slip
higher than the fill load current.If the motor
is "driven"at no slip than there is no current
consumed that means there is no induced emf in
the rotor as Amit Mohan has said.That means
you are driving the motor instead of the motor
driving anything
nothing would happen to the motor, you are just
turning the motor at syn speed.
