Abstract:

The rotor structure of low-speed and high-torque permanent magnet motor has larger optimization space. The main stress of low-speed and high-torque motors was analyzed. The most suitable rotor structure of low-speed and high-torque motor was obtained through the comparison of two typical rotor support structures. Optimized analysis were carried out for this rotor structure, and the influence rules between stiffness, strength and rotor structural parameters were found out. The optimal design method of low-speed high-torque motor rotor was summarized, which provides a basis for the rotor structure design of low-speed high-torque motors.

Key words: low-speed high-torque, rotor structure, optimization
