Research and Design of Low Slot Torque Low Temperature Rise Motor Technology
The cogging torque affects the rotational stability of the motor,the temperature rise affects the in-sulation 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 el-ement 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 simula-tion 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.
