Abstract


In order to meet the development requirements of micro-electric vehicle in efficiency, reliability and safety, thermal loss mechanism and temperature influence factors of in-wheel motor are study. The finite element method is used to simulate and analyze internal complex thermal loss and temperature field. The mathematical model of thermal loss and temperature field was established. The united simulation model of in-wheel motor was established by Ansoft Maxwell and Ansys Workbench software, transient state temperature were simulated and analyzed. The influences of load and revolving speed on temperature rise were also studied. The conformity of the test results with the final simulation results indicates that this method can be used to provide a theoretical basis to make further optimal design of the new driving in-wheel motor.
