The two rear tires of the permanent magnet brushless motor are driven separately,and this type of simulation target chassis has better controllability,shorter digital and unmanned research and development cycles compared to traditional fuel simulation chassis targets.Moreover,the transmission efficiency and operating cost of the permanent magnet brushless motor chassis under operation have more obvious advantages than ordinary car chassis.Based on the rapid development of the new energy chassis field at present,the article studies the wheel electric chassis drive system,elaborates on the theoretical basis of permanent magnet brushless motor motors,and conducts certification according to the research methods.During the experimental process,it is first ensured that the main parameters are paired and comply with the dynamic performance regulations of the vehicle.A permanent magnet brushless DC motor with an outer rotor is proposed,including the construction of the magnet,wheel size configuration,selection of permanent magnet ferrite and driving power supply,and the optimal scheme for pairing the main parameters.A digital model is also constructed for testing.
