一种新型永磁电机转子的研制

摘要

A new type of rotor structure of permanent magnet motor was introduced. The dovetail groove in the external circular surface of the rotor was machined,and the dovetail groove was staggered in distribution. The alnico magnets were inserted into the dovetail groove piecewise outside the rotor,and the end was fixed with a retaining ring. Convenient installation and fixing were made by this structure of magnets,and the accident of the magnets falling off was avoided. The operation stability of the motor is effectively improved by the piecewise staggered distribution of magnets,and the vibration and noise of the motor are reduced.%　　介绍了一种新型的永磁电机转子结构，在转子的外圆表面加工有纵向错齿分布的燕尾槽，转子外的磁钢分段插入燕尾槽中，末端用挡圈固定。该结构磁钢安装固定方便，避免了磁钢脱落事故的发生，磁钢的分段错齿分布也有效地提高了电机运转的平稳性，同时降低了电机的振动和噪声。
