Simulation and analysis on annealing temperature field of motor electromagnetic wire

The dedication electromagnetic wire of certain a high-speed heavy traction motor is regarded as a research object, by virtue of the software Star-CCM+ as well as the fluid-solid coupling simulation technology, the annealing temperature field is numerically simulated by sufficiently considering the influence factors such as various heat conduction forms: heat conduction, convection, radiation and contact, as well as circulating fan and temperature-measuring steel pipes, etc. The basic coincidence between simulation results and really tested temperature values proves the correctness of the research method. Furthermore, the relationship between difference annealing temperatures and the mechanical performances can provide theoretical guidance for the optimization of annealing process of electromagnetic wires.
