Abstract:
In the process of parameters matching study of driving motor for electric vehicle, an optimal design method for structural parameters of driving motor was proposed. Based on the basic given motor parameters, the influences of axial length, rotor outer diameter, winding turns, wire diameter, pole arc factor, and permanent magnet thickness on motor efficiency were analyzed. The mapping relationships between the main ontology structural parameters and the efficiency characteristic of the motor were established. The procedures of the preliminary design and the optimal design for the motor ontology structural parameters were proposed. Based on the optimized motor efficiency characteristic, the economic performance of whole vehicle was simulated and verified by using the forward-facing simulation vehicle model under 4 typical working conditions. Simulation result shows that in the aspect of output characteristic, compared with the initial motor, the torque ripple of optimized motor reduces obviously, the value in constant torque area reduces to 14%, the value in constant power area reduces to no more than 40%, and the top efficiency increases to 94%. In the aspect of whole vehicle economy performance, the energy consumptions per kilometer of optimized motor for whole vehicle reduce by about 7.1%, 6.7%, 4.1%, and 2.9% under NEDC、UDDS、JC08、1015 working conditions, and the average value is 5.2%. Under the premise of meeting the driving requirements, the operating point distribution in higher efficiency range is improved, and the average efficiency in the area with higher rotational speed and lower torque rises significantly by using the proposed optimal design method. The design method can better improve the driving efficiency of motor, and can supply the theoretical supervision for the optimal design of driving motor ontology structural parameters according to the requirement of vehicle performance. 5 tabs, 22 figs, 25 refs.
