The invention provides a current multiplexing aging circuit and method for a brush motor driver, N+1 brush motor drivers and N DC power supply generation sub-circuits are alternately connected between a DC power supply and a load in series based on the design principle of current multiplexing, the design that N + 1 brush motor drivers are subjected to aging at the same time through one direct-current power source and one load is achieved, the aging capacity is improved by N times, the aging efficiency is high, resources such as the direct-current power source and the load needed for aging on each brush motor driver are relatively few on average, and the aging cost is reduced; meanwhile, through current multiplexing, the aging energy consumption on each brush motor driver is greatly reduced on average, the aging cost is further reduced, and the circuit and method are suitable for aging of a large batch of brush motor drivers. 本发明提供一种有刷电机驱动器的电流复用老练电路及方法，基于电流复用的设计原理，将N+1个有刷电机驱动器与N个直流电源产生子电路交替串设在直流电源与负载之间，实现了一个直流
