摘要
根据内置式永磁同步电动机转子的结构特点和永磁体材料的温度特性,研究转子铸铝的特殊加工工艺,解决转子铸铝时铝液易渗入转子磁体槽的问题。设计钕铁硼永磁体的压力装配工装模具,实现转子中的永磁体由机械压装替代传统的手工装配,在内置式FYT300永磁同步电动机的批量生产中,验证了工艺的可靠性和有效性,提高了转子磁体的装配效率和装配质量。
According to the characteristics of the rotor structure of magnetic rotor for interior permanent magnet syn- chronous motor and the temperature characteristics of permanent magnet material, the special process of cast aluminum rotor was researched to solve the problem that aluminum liquid is easy to permeate into the rotor magnet slot when the rotor cast aluminum. By designing the pressure assembly tooling of NdFeB permanent magnet pressure assembly tooling, for the rotor magnet, the traditional manual was replaced by assembly mechanical pressing. In mass production of the built-in FYT300 of permanent magnet synchronous motor, we verify the reliability and effectiveness of the process and this approach improves the assembly efficiency and assembly quality of rotor magnet.
