Since 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, they relay in the control box, AC contactor, frequency sensitive rheostat and other electrical components to form a complete system of the secondary circuit, as motor starting and means of running shorting. This way of working of the motor has the following disadvantages: 1, carbon brush is easy to wear, excessive 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, increases the contact resistance, the motor temperature rise. 4, conductive powder is easily inhaled inside the motor and is a serious hazard of burning motor. 5, the time relay uncontrolled easy to burn AC contactor and frequency sensitive rheostat
