Abstract：The universal application of three-phase AC induction motor autotransformer for starting by reducing voltage which is controlled one to one, this article describes the method by using an auto-transformer to drive three motors, and provides the main circuit and control circuit. This method can reduce the equipment cost and ar?ea. Through practical applications, it indicates that the device is stable and reliable, it can be extend widely.
