| Abstract: | The starting process ofwound induction motor by adding resistance to the rotor circuitthrough series connection is analyzed.The rotor circuit of the motor is innovated and the frequency-sensitive variable resistance is replaced by water resistance.The starting currentis lowered,the starting torque is increased,and atthe same time the power factor is increased above0.9,good economic benefic is achieved. |
