DGVCL Exam Paper (11-12-2011)
The advantage of slipring induction motor over the squirrel cage induction motor is
It is suitable for higher speedsIt can be started with the help of rotor resistancesIt has a higher efficiencyIt's power factor is higher
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.
