Switched reluctance motor (SR motor) exhibits desirable features including high reliability, good efficiency and low cost because the SR motor has simple and solid structure without permanent magnets and rotor windings. Unfortunately, the SR motor has not been put into practical applications widely because of its large torque ripple and acoustic noise. However, recent motor technology, which includes an optimum design based on FEM and instantaneous current control using DSP or FPGA, overcomes gradually the defects of the SR motor. Some products such as fuel pump, washing machine and vacuum cleaner have been already presented in the practical applications of SR motor.In this research, we proposed an outer rotor type multi-polar SR motor as a new attempt, and developed a multi-polar SR motor to an small electric vehicle for two years. The obtained results are as follows :The results obtained in the year 20041. Establishment of dynamic analysis method for SR motor.2. Design of the outer rotor type multi-polar SR motor for electric vehicle.3. Manufacturing of the outer rotor type multi-polar SR motor for electric vehicle.4. Manufacturing of the driving circuit and controller for the outer rotor type multi-polar SR motor.The results obtained in the year 20051. Manufacturing the electric vehicle with the developed multi-polar SR motor, the driving circuit and controller.2. Improvement of the driving circuit and controller for the purpose of reliable operation.3. Driving experiments.4. Proposal of new control methods of the SR motor for improvement of the performance of the electric vehicle.5. Establishment of the optimum design method of the SR motor.To conclude, we developed a new outer rotor type multi-polar SR motor and realized a direct driving electric vehicle using the developed SR motor in this research. The electric vehicle has good performance. Then the original target of this research has been accomplished.

开关磁阻电机（SR电机）结构简单、坚固，无需永磁体和转子绕组，具有可靠性高、效率高、成本低等优点。但由于SR电机转矩涟漪大、噪声大等原因，至今未能得到广泛的应用。然而，最近的电机技术，包括基于有限元的优化设计和使用DSP或FPGA的瞬时电流控制，逐渐克服了SR电机的缺陷。SR电机在燃油泵、洗衣机、吸尘器等产品中已经有了实际应用，本课题提出了外转子式多极SR电机作为一种新的尝试，并在小型电动车上进行了为期两年的多极SR电机的研制。获得的结果如下：20041年获得的结果。SR电机动力学分析方法的建立.电动汽车用外转子式多极SR电机的设计.电动汽车用外转子式多极SR电机的研制.外转子型多极SR电动机驱动电路及控制器的制造。20051年取得成果。利用所研制的多极SR电机、驱动电路和充电器制造电动汽车.对驱动电路和控制器进行了改进，使其工作可靠.驾驶实验。4.提出了新的SR电机控制方法，以提高电动汽车的性能.建立了SR电机的优化设计方法。综上所述，本研究开发了一种新型的外转子式多极SR电机，并利用所开发的SR电机实现了直接驱动电动汽车。电动汽车具有良好的性能。从而达到了本研究的预期目标。
