摘　　要：空心杯感应电机因其转子结构简单牢固、转动惯量小、易于与传动对象集成等优点,适合于涡轮分子泵等高速领域。与笼型高速感应电机相比,空心杯感应电机有效气隙长度较大,引起功率因数和输出功率均有所降低,使其难以推广应用。用浮动桥逆变器对空心杯感应电机进行无功补偿,使电源逆变器达到单位功率因数,提高电机的输出功率。通过ANSYS电磁仿真软件对空心杯感应电机进行建模仿真,验证了该方法的有效性。Drag-cup induction motor is suited for high-speed areas such as turbo molecular pump,because of its simple and robust structure,small rotor inertia and easy integration with drive system.The drag-cup motor has large effective air gap length,resulting in lower output power and poorer power factor as compared with cage-rotor type.The reactive power of drag-cup induction motor was compensated by the floating capacitor bridge,while the unity power factor of source inverter could be achieved.The drag-cup motor model was built in ANSYS electromagnetic simulation software and the effectiveness of the proposed method was verified.
