The invention relates to a protection system for an aircraft electric propulsion motor and a motor controller. A method for protecting an electric propulsion system in response to the occurrence of a fault. In one embodiment, a method includes activating a power switch of an inverter in a motor controller to short-circuit to redirect current regenerated by a motor electrically coupled to the motor controller and mechanically coupled to a propeller. The method further includes feathering the propeller while the motor regenerates the current. The protection logic is designed to address different types of faults, including faults in the high voltage direct current bus, faults in the motor controller, and faults in the motor.
本公开涉及用于飞行器电力推进电机与电机控制器的保护系统。一种用于响应故障的发生而保护电力推进系统的方法。方法包括下列步骤：激活电机控制器中的逆变器的电源开关发生短路，以对由电机再生的电流进行重新导向，电机电耦接至电机控制器并且机械地耦接至螺旋桨。方法进一步包括：在电机再生电流的同时，使螺旋桨顺桨。保护逻辑被设计成解决不同类型的故障，包括高压直流电流总线中的故障、电机控制器中的故障以及电机中的故障。
