  • Publication number: 20250023501
    Abstract: The present application discloses a motor control method and apparatus, an electrical device, and a storage medium, where a neutral wire of a motor is connected to at least one standby power device, the method including: determining motor faulty phases if it is detected in an operating process of the motor that the motor is faulty; and controlling the motor faulty phases to switch from currently connected primary power devices to the standby power device. In the present application, when the motor is faulty, switching from the primary power devices for the motor faulty phases to the standby power device is performed. By replacing the primary power devices corresponding to the motor faulty phases with standby power devices, the motor can continue to operate after it is faulty, and there is no safety risk due to the motor faulty phases during the operating process.

  • Publication number: 20250023374
    Abstract: The present application discloses a method, apparatus, system, device and storage medium for controlling a charge and discharge circuit. The charge and discharge circuit includes an M-phase motor winding, where M is a positive integer. The method includes: controlling the charge and discharge circuit to start charge and discharge; acquiring a first current value and second current values, where the first current value is a current value flowing through a neutral line of the M-phase motor winding, and the second current value is a current value flowing through a single winding; determining whether a current charge and discharge state is normal according to the first current value and the second current values; and if not, controlling the charge and discharge power to be reduced.

  • Patent number: 10914006
    Abstract: A nanoparticle continuous-coating device based on spatial atomic layer deposition. A first-stage pipeline unit, a second-stage pipeline unit, a third-stage pipeline unit and a fourth-stage pipeline unit which are connected sequentially. The first-stage pipeline unit is used for providing a first precursor and enabling the first precursor to be adsorbed on surfaces of nanoparticles. The third-stage pipeline unit is used for providing a second precursor and enabling the second precursor to react with the first precursor on the surfaces of the nanoparticles, so that a monomolecular thin film layer is generated on the surfaces of the nanoparticles. The second-stage and fourth-stage pipeline units are used for cleaning the nanoparticles and discharging the redundant first precursor, the redundant second precursor or reaction by-products.

  • Publication number: 20200131637
    Abstract: A modular injector includes a precursor channel assembly and a seal assembly; the precursor channel assembly includes a plate-shaped base, a precursor channel and a gas pipeline; the precursor channel is disposed on a front surface of the plate-shaped base and extends from top to bottom, and a top end of the precursor channel is communicated with the gas pipeline; the seal assembly is disposed on the front surface of the plate-shaped base. The modular injector includes a plurality of components to form an integral module, and shunts and buffers the introduced gas through the precursor channel to achieve uniform deposition. A device includes multiple modular injectors arranged at an interval, into which the oxidant precursor source and the organo-metallic source are respectively introduced, so that multiple stages of film are deposited on the substrate after the substrate moves for a round trip.

  • Patent number: 8104492
    Abstract: An adjustable offset umbrella has a generally vertical main pole and a sliding member slidably mounted to the main pole. The sliding member includes a locking mechanism for securing it at a desired location along the main pole. One end of an arm is associated with the sliding member, and the other end supports an umbrella canopy. A winding mechanism is associated with the sliding member and moves with it. A line extends from the winding mechanism to the umbrella canopy. Operating the winding mechanism opens and closes the umbrella canopy, and moving the sliding member up or down the main pole adjusts the angle of the canopy with respect to the main pole.
