齿槽转矩影响电机的转动平稳性,温升影响电机自身绝缘可靠性,同时也影响系统工作运行环境。针对低齿槽转矩低温升电机的需求,文章围绕低齿槽转矩、低温升等电机设计的关键技术,通过理论分析及有限元仿真优化设计,研制出一款额定输出转矩不低于25Nm,齿槽转矩不大于80mNm,机壳表面温度不大于35℃的低齿槽转矩低温升液冷电机,并通过试验数据验证了理论分析与仿真方法的准确性。相关工作为低齿槽转矩低温升液冷电机的设计开发提供一定参考价值。

The cogging torque affects the rotational stability of the motor,the temperature rise affects the insulation reliability of the motor itself,and also affects the operating environment of the system.In response to the demand for low cogging torque low-temperature rise motors,this article focused on key technologies in motor design such as low cogging torque and low-temperature rise.Through theoretical analysis and finite element simulation optimization design,a low cogging torque low-temperature rise liquid cooled motor with a rated output torque of no less than 25Nm,a cogging torque of no more than 80mNm,and a shell surface temperature of no more than 35℃has been developed.The accuracy of the theoretical analysis and simulation methods has been verified through experimental data.The relevant work provides certain reference value for the design and development of low cogging torque low-temperature liquid cooled motors.
