Abstract: In order to eliminate the hub motor control system failure caused by rain, snow, dust and poor heat dissipation during the operation of a hub permanent magnet synchronous motor. This paper designs a dual processor control system for a hub permanent magnet synchronous motor. In normal operation, the motor is driven by the main processor.When the main processor fails, the fault signal is sent to the auxiliary processor through the communication bus and switched to the auxiliary processor to drive the motor, which effectively improves the motor control system security and reliability.

摘要： 为排除轮毂永磁同步电机在工作运行中因雨雪、灰尘以及散热不良等诸多因素造成的 轮毂电机控制系统故障，文章设计了一种轮毂永磁同步电机双处理器控制系统，在正常运行 状态下，由主处理器驱动电机工作。当主处理器出现故障时，通过通讯总线将故障信号送至 辅助处理器，并切换至辅助处理器驱动电机工作，有效地提高了电机控制系统的安全可靠性。
