I have a question regarding INDUCTION MOTOR. In v/f method of speed control of IM we change both the parameters inorder to keep ratio constant so that, torque remains contant also if one of the parameter is varied keeping other constant (voltage increased or frequency decreased) it causes flux saturation. if these happens practically, stator winding will burn due to increased magnetising current. but if stator winding does not burn may be we have best cooling technic then How it will affect stator and rotor? will it affect them permananlty or come back to its original state if resetted again???
