“…The associate editor coordinating the review of this manuscript and approving it for publication was Zhuang Xu . In recent years, many researches on the motor heating and cooling problems have been carried out from the perspective of fluid flow and heat transfer [7], [8]. Xu et al increased the air flow to improve the heat transfer capacity of the cooler by adjusting the height of the windshield, increasing the number of the windshield, and changing the shape of inclined plate [9].…”

A 160kW and 60r/min low speed and high torque permanent-magnet synchronous motor is studied. According to fluid mechanics and heat transfer theories, a motor temperature field calculation model is established. The motor fluid field and temperature field are coupling solved by the finite volume method, and the steady-state temperature distribution of the motor is obtained. In addition, the cooling wind thorn is added on the end face of rotor core in order to solve the high temperature rise problem of permanent magnet. The influences of the geometric parameters of the cooling wind thorn on the fluid field and temperature field are analyzed by simulation, and the optimum size of the wind thorn is obtained for the best thermal performance. As the highest temperature rise is located at the end of the stator winding, the winding temperature rise is reduced by sealing the thermal conductive adhesive between the motor shell and the end of the winding. The influences of different sealing solutions and thermal-conductivity adhesives on motor heat transfer are also simulated.INDEX TERMS Low speed permanent-magnet motor, optimization of heat dissipation structure, cooling methods, temperature field.

This paper aims to propose a method to determine the temperature rise and rated capacity of induction motors under different working systems. A dynamic mathematical model, a 3D temperature field model, and finite element method are used to analyze the electromagnetic loss and transient temperature rise, respectively. The influence of the motor starting process on the temperature rise is taken into account, which resolves the complex loading of transient heat source. The maximum allowable running times for the motor operating with different overloads are determined. The relationship between the motor output power and the allowable running time is obtained, and it provides a basis to determine the rated capacity of motor under S2 working system. The relationship between the motor output power and the temperature rise under different load duration rates is also obtained and provides reasonable evidence to determine the rated capacity of the motor under S3-working system.
