  • Patent number: 10985564
    Abstract: An electric power-regulating system includes an electric-load end, a power-supply end, a power regulator, a DC-bus device, a flywheel energy-storage device, a switch device and a controller. The flywheel energy-storage device connects the DC-bus device. The switch device is connected between the flywheel energy-storage device and the DC-bus device. The switch device provides at least one current-flow direction between the DC-bus device and the flywheel energy-storage device. The controller controls the power regulator and the flywheel energy-storage device. When a voltage of the DC-bus device exceeds a operation range, the controller selectively limits the current-flow direction of the switch device. Further, when a voltage-bias direction of the switch device and the current-flow direction are the same, the controller allows a current of the DC-bus device to flow into or out of the flywheel energy-storage device in the current-flow direction. In addition, an electric power-regulating method is also provided.

  • Publication number: 20210021172
    Abstract: A kinetic energy recovery system with flywheel includes a cascade flywheel doubly-fed electric machine. The cascade flywheel doubly-fed electric machine has a stator end coil, a rotor end coil and a flywheel. The flywheel can store kinetic energy by increasing speed or releasing kinetic energy by decreasing speed. A control circuit has an inverter, a rectifier and a DC bus connecting the inverter and the rectifier. The inverter is used to supply alternating current to the rotor end coil. The rectifier has an AC end connected to the stator end coil through an AC bus. The rectifier converts alternating current to direct current, so that the inverter can draw power from the DC bus. An electric motor has a phase coil connected to the AC bus. When the cascaded flywheel double-fed electric machine decelerates, the kinetic energy recovery system with flywheel will convert mechanical energy into electrical energy.

  • Patent number: 9006953
    Abstract: A stator assembly structure for an axial flux electric machine is designed. The back iron for each silicon steel disk stator is formed into a specific structure with tooth-like protrusions for allowing the same to be integrated with the disk-type stator seat, while the disk-type stator seat is made of a material suitable for casting or mold forming. A coil is mounted on the disk stator, and a stator assembly is achieved by integrating the stator, the coil and the stator seat. The stator and the disk-type stator seat of the stator assembly are manufactured by using a one-piece cast or one-piece mold forming method so as to enable the contact surfaces of the stator and the stator seat to engage with each other even more tightly, and consequently enable the heat generated from the coil to be transmitted rapidly from the disk stator to the disk-type stator seat.
