The Electromagnetic and Thermal Analysis of Permanent Magnet Brushless DC Motor in Cars
Abstract:
As the wide application of DC brushless motor in cars, this paper introduces a kind of motor design method that based on finite element theory. The motor electromagnetic simulation is analyzed by using finite element termed as Ansoft, the simulation results and experimental data are anastomotic, so the method is verified feasible. The motor in cars is restricted to the volume, the motor temperature index influence all basic parameters seriously, in this paper baseing on the motor loss simulate the motor 3D temperature distribution, and find out the highest spot, for designing the cooling system of similar motors provide instructional effect, and this is of important engineering significance.
