Its rotor external resistance or reactance, high power factor and high starting torque at start, in the fields of metallurgy, machinery, chemicals, mining, building materials commonly used in this motor to Drag the device. Slip ring, carbon brushes, short-circuit ring is mounted on the motor shaft parts, and the relay in the control box, AC contactor, frequency sensitive rheostat and other electrical components to form a complete secondary loop system, as a motor shorting means for starting and running. This way of working of the motor has the following disadvantages: 1, carbon brush is easy to wear, high consumption, the amount of maintenance, and affect the normal production. Between brush and slip ring is easy to produce sparks, some places can not be used. 3, brush and slip ring friction, increasing the contact resistance, the motor temperature rise. 4, the conductive powder is easily inhaled inside the motor,
