摘　　要：U形铁心单相交流永磁同步电机起动力矩小,应用于水泵叶轮驱动时,需要考虑减小电机起动时的转子阻力矩。文章从电机起动原理着手,阐述了转子自由行程设计的必要性,并介绍了几种结构形式。Because of the small starting torque of the U-shaped core, single-phase, AC PM synchronous motor, how to reduce the rotor anti-resistance torque should be taken into account when driving water pump impeller. Necessity of the free-path design for rotor was described in point of view from starting principle of the motor, and then, several kinds of construction of the free-path were introduced.
