The invention provides a fault protection method and device for a motor controller, electronic equipment and a storage medium, and the method comprises the steps: obtaining fault information of the motor controller; when the fault information shows that the driving circuit of the motor controller is normal, selecting a first safety state or a second safety state to carry out fault protection; when the fault information shows that the control unit of the motor controller is normal, selecting a third safety state to carry out fault protection; and when the fault information shows that the control unit of the motor controller cannot normally control the bipolar transistor, selecting a fourth safety state to carry out fault protection. By implementing the application, a fault protection state can be entered through multiple ways, hardware is effectively protected, feedback after a fault occurs is more timely, selection of a safety state is more flexible and changeable, and safety in the operation process of the motor controller can be considered.

    本申请提供一种电机控制器的故障保护方法、装置、电子设备及存储介质,其中,该方法包括:获取所述电机控制器的故障信息;当所述故障信息显示所述电机控制器的驱动电路正常时,选取第一安全状态或第二安全状态进行故障保护;当所述故障信息显示所述电机控制器的控制单元正常时,选取第三安全状态进行故障保护;当所述故障信息显示所述电机控制器的控制单元无法正常控制双极晶体管时,选取第四安全状态进行故障保护。实施本申请,可以通过多种途径进入故障保护状态,有效保护硬件,对故障发生后的反馈更加及时,对安全状态的选择也更加灵活多变,可以兼顾电机控制器运行过程中的安全性。
