Three-phase AC induction motor is simple in structure, operation and reliable, cheap, strong and Guozainengli use, installation, maintenance and other advantages of convenience, are widely used in various fields. But big is the starting current conventional induction motor total of a prominent shortcomings, is generally rated at about six times. Starting current big impact on the grid, the impact load, the impact on the surrounding electrical appliances, in the frequent occasions and small start-up network is particularly prominent. To improve the exchange of motor starting performance, lower starting current and upgrade starting torque, the traditional method of starting a series buck saturated reactor, Y-Δ transform, auto-transformers and other equipment, although effectively curbed a starting current However, without exception, the lack of existence: starting current reduced, while the starter motor torque-square relations also decreased, and the starting current is not continuou
