摘要：

Low-speed high-torque synchronous motor (LSHTSM) is widely used in many fields. In order to solve the problem of underutilized internal space, low torque density, high cost and high temperature demagnetization of the existing low speed and high torque permanent magnet motor, a permanent magnet/ reluctance hybrid rotor double-stator LSHTSM was studied, and the topological structure and mechanical structure of the proposed motor were introduced. For the complex structure of the proposed LSHTSM and the difficulty in calculating the temperature quickly and accurately, the accurate temperature calculation model based on the thermal network of the motor was established, and the mathematical model of thermal resistance between the special structural components of the motor was deduced in detail. The steady-state temperature of each structure of the motor was analytically calculated, and the temperature distribution characteristics of this kind of motor were summarized. Because of the special structure and difficult heat dissipation of the motor, a cooling system with double water cooling way was designed, and the influence of the structural parameters of the cooling system on the cooling effect of the motor was analyzed. Furthermore, the design principles of the motor cooling system with this special structure were summarized. Finite element simulation and experimental methods were used to verify accuracy of the thermal network temperature calculation model and effectiveness of the cooling system. © 2023 Editorial Department of Electric Machines and Control.
