Simulation Researches on Thermal Characteristics of Vehicular In-wheel Motors

摘要

The thermal characteristics of In-wheel Motor is one of the key technologies for the motors used in the New Energy Vehicles. In this paper, the thermal simulation model of in-wheel motor used for solar car was established, the thermal characteristics of In-wheel motor were analyzed by building the mass flow and heat-transfer coupling simulation model. The motor temperature field data were acquired by simulation combined with the actual work conditions. The simulation air cooling model of in-wheel motor and verification researches were carried out, which provides the basis for the further thermal design and optimization of In-wheel motor structure.
