| 摘要: |
| 为了提高直驱型电动舵机的可靠性和容错性、减小直驱型电动舵机的体积和重量，设计具有容错能力的电机。分析直驱型电动舵机中电机的容错性，设计了满足容错需求的三相24槽20极表面式永磁同步电机，对电机尺寸参数进行优化，建立该电机的有限元仿真模型，并对其开路和短路故障进行有限元仿真分析。有限元仿真结果表明，所设计的电机具有很强的磁隔离和故障隔离能力，能够满足直驱型电动舵机的容错性需求。 |

| Abstract: |
| The design of fault tolerant motor was studied in order to minimize the volume and weight of direct drive electromechanical actuator, and to improve the fault tolerant and reliability. The design requirements of fault tolerant motor were analyzed, and a three-phase twenty-four-slot twenty-pole surface permanent magnet synchronous motor was designed to meet the requirements. The parameters of the motor were optimized. The finite element model of the motor was established to simulate a single phase short circuit or open circuit fault. The simulation results show that the motor has a perfect property in the magnetic isolation and fault tolerant, and can meet the fault tolerant requirements of direct drive electromechanical actuator. |
