Review of research on analysis and design of high torque overload capability motors
As an electromechanical energy conversion device,motors are widely used in electric vehicles,aerospace,energy metallurgy and other fields,but their operating scenarios vary widely.In order to adapt to the operating char-acteristics of the load under different scenarios and working conditions,the motor usually needs to have a certain torque overload operation ability.Accurate analysis and utilization of the torque overload capacity of the motor is of great significance to improve the economy of the system and realize energy saving and consumption reduction.This paper firstly introduces the motor torque overload capacity and utilization methods,and summarizes the application scenarios and practical value of high torque overload capacity motors.The electromagnetic characteristics,loss char-acteristics and temperature limit of motor torque overload operation are analyzed.The constraint conditions and utili-zation boundary of motor design with high torque overload capacity are summarized.The research status of permanent magnet synchronous motor and asynchronous motor with high torque overload capacity is analyzed and summarized re-spectively,and the strategies to improve the torque overload capacity of the motor are sorted out.Finally,the devel-opment direction of research and utilization of high torque overload capacity motor is prospected.
