The power supply of the hysteresis motor adopts a three-phase square wave power supply. In order to improve the working performance of the hysteresis motor, a control strategy of high voltage fast start and low voltage maintenance operation is adopted. However, the anti-overload ability of hysteresis motors is poor during low voltage operation. In order to solve the problem of current increase and inability to recover under strong interference during the use of hysteresis motors, this article adopts sharp pulse power supply technology to improve the current increase and recovery ability of hysteresis motors. Finally, a sharp pulse power supply with adjustable width, amplitude, stacking position, and pulse number was developed. Experimental analysis was conducted on the working state and overload resistance of the hysteresis motor under different sharp pulse power supply excitations, and the optimal power supply state suitable for the hysteresis motor was obtained. This achieved the goal of reducing the working voltage and improving the disturbance resistance of the hysteresis motor by exciting it with a sharp pulse power supply.
