摘要:
 较大齿槽转矩的存在不仅影响电机的性能,而且还会使电机产生较大的振动和噪声,严重缩短了电机的使用寿命。从电机的齿槽转矩公式出发,研究闭口槽结构及参数对电机齿槽转矩和振动噪声的影响;采用有限元的方法,针对这一问题提出的结构进行了仿真,详细地分析了闭口槽结构对反电动势、齿槽转矩、平均转矩的影响规律,并进一步分析了电机的振动和噪声。研究表明,采用定子闭口槽结构可有效地减少永磁电机的齿槽转矩,电机的振动加速度得到了大幅减低。
Abstract:
 Cogging torque is one of the important performance indexes of permanent magnet motor. The torque performance of motor is not only affected by cogging torque,but also produces greater noise and vibration. Meanwhile, the life of the motor will be seriously reduced. The cogging torque formula of the motor is proposed firstly. The influence of structure and parameters of motor with segmental stator and closed-slot on cogging torque is analyzed. The structure proposed in this paper is simulated by the finite element method. The rule of Closed-Slot structure on cogging torque is studied in detail. The vibration and noise of motor are also investigated in this paper. The results show that the cogging torque a can be effectively reduced by adopting segmental stator and closed-slot structure. The motor vibration acceleration reduces substantially.
