Although the technology of tram is relatively mature, its energy utilization has not yet reached a high level. At present, when the tram brakes, it passes through the brake pads. For main braking, as shown in Figure 1, the motor generates power to the battery for auxiliary braking, and the braking energy is lost in the form of friction braking. As a result, the friction plate is consumed quickly, and the manufacturing process of the spinning brake vacuum pump is complicated and the reliability is not good.
