can induction motor run over the rated speed ?
Answer Posted / swapnil patil
An induction motor rotor runs because of the torque created
in the rotor which is directly proportional to the relative
speed between rotor and stator.When motor tries to achieve
the synchronous speed, relative speed becomes zero and so
the torque also becomes zero.So induction motor can never
run at a speed more than or equal to synchronous
speed.Rated speed refers to speed of motor at full
load.Motor can have speed greater than rated speed butnot
beyond synchronous speed.
