  • Double squirrel cage motorelectricaleasy

    Squirrel cage motors are the most commonly used induction motors but the main drawback in them is their poor starting torque due to low rotor resistance. (Starting torque is directly proportional to the rotor resistance).But increasing the rotor resistance for improving starting torque is not advisory as it will reduce the efficiency of the motor (due to more copper loss).
