  • Publication number: 20240100880
    Abstract: A multi-piece wheel frame includes a rim and a disc. The rim includes a barrel, and an outer rim portion protruding outwardly from the barrel. The outer rim portion forms an inclined surface, and a ring edge surface connected to an outer edge of the inclined surface and cooperating with the inclined surface to form an obtuse angle. The disc is fixed to the rim, and includes a disc core, a plurality of spoke portions extending radially outwardly from the disc core, and a reinforced ring portion connected to the spoke portions and fixed to the outer rim portion. The reinforced ring portion abuts against at least one of the inclined surface and the ring edge surface.

  • Patent number: 11923794
    Abstract: A motor control apparatus receives a DC power source through a DC terminal and is coupled to a motor. The motor control apparatus includes a brake, an inverter, and a controller. The brake is coupled to the inverter. The brake includes an energy-consuming component and a switch component. The controller controls the inverter to convert the DC power source to drive the motor. When the controller determines that the DC power source is interrupted, the controller stops controlling the inverter, and the switch component is self-driven turned on so that a back electromotive force generated by the motor is consumed through the energy-consuming component.

  • Patent number: 11463037
    Abstract: A motor control system is coupled to an input power source and a motor. The motor control system includes an inverter, a brake, and a controller. The inverter includes a plurality of upper-bridge transistors and a plurality of lower-bridge transistors, and the brake includes a plurality of loop switches. Each loop switch includes a first end, a second end, and a third end, and the third ends are respectively coupled to control ends of the lower-bridge transistors. The controller is coupled to the first end, and when the controller detects that the input power source is greater than a low-voltage protection value, the controller controls the third end to be coupled to the first end, and provides an upper-bridge drive signal assembly to operate each upper-bridge transistor, and provides a lower-bridge drive signal assembly to operate each lower-bridge transistor.
