DGVCL Exam Paper (11-12-2011)
A 3 phase, 6 pole induction motor operates on 440 V, 50 Hz, supply. If the actual speed of the motor is 960 rpm the slip will be
In all machine stator and rotor magnetic field rotates (stationary with respect to each other) at synchronous speed with respect to stationary observer.
slip ring motor have high starting torque compare to squirrel cage motor and have good speed control also have high over loading capacity, smooth acceleration under heavy loads.
