| 摘要: |
| 针对电动汽车驱动电机既要满足低速区大转矩输出，同时又要满足高速恒功率区宽弱磁调速范围的特殊需求，提出采用 V 型转子磁路结构的内置式永磁同步电机作为驱动电机;通过对影响这种结构电机运行特性的主要参数理论分析表明:提高内置式永磁同步电机交轴电感 L q 参数值，不仅有利于提高电机恒功区弱磁扩速范围，而且同时也满足低速区的大转矩输出要求。同时，采用这种结构设计了30 kw 电动汽车驱动用内置式永磁同步电机，结合有限元对样机主要性能进行了电磁场计算;并对样机进行了参数实验、空载实验、负载实验。通过对比分析，样机实验测试结果与设计计算值、电磁场仿真计算结果相吻合，表明所研究 V 型内置式永磁同步电机结构及提高电机交轴电感 L q 参数的设计方法是一种能够满足电动汽车驱动电机输出特性需求的有效方法。 |

| Abstract: |
| In this paper,the main parameters influencing motor running characteristics are analyzed in depth fordriving requirements under each of different running conditions of IPMSM for electric automobiles.In order to a-chieve maximum output torque under low speed operating conditions and to extend the field weakening range of themotor at high speed constant power operating conditions,the quadrature axis inductance parameter values Lq ofIPMSM should be improved to the greatest extent possible during design.Furthermore,a 30 kw prototype of IPMSMis designed for traction electric automobiles; the main performances,including that of electromagnetic field,of the30 kw prototype are analyzed with finite element method; then the experimental parameters,no-load test and loadtest of the 30 kw prototype are accomplished.The calculation results with FEM agree with the experimental resultsfor the 30 kw prototype; these results and their analysis show preliminarily the validity of the design and analysis. |
