A new type of stator double-fed brushless inverter motor is proposed. When it is used to drive a pump-like load, it not only offers the energy-saving benefits of conventional variable-frequency speed regulation but also significantly reduces the capacity of the drive required. This paper introduces the structure and working principle of this kind of motor, and gives the speed control characteristics of the experimental prototype. The advantages of using it for pump loads are analyzed.
