  • Patent number: 11611252
    Abstract: An driving motor with hybrid excitation of electromagnetism and invisible magnetic pole, wherein each magnetic pole comprises two first magnets, one second magnet and one third magnet; wherein the first magnet is placed along a diameter direction of a rotor core, the second magnet is located at a middle and lower portion of two first magnets of each magnetic pole corresponding to the second magnet at a diameter direction, and a magnetic isolation groove is disposed at an inner end of the first magnet and extends toward two sides of the inner end of the first magnet. The magnetic isolated air gap can adjust a spatial distribution of a magnetic field generated by permanent magnets of each pole to replace the permanent magnets, so as to save the number of the permanent magnets, reduce the weight of the motor, and reduce the cost of the motor.

  • Publication number: 20210108714
    Abstract: The present invention discloses an intelligent lubricant spraying system for a high-speed gear transmission, which comprises an oil tank, an oil pump, a driving gear, a driven gear, and a spray nozzle. One end of the oil pump is communicated with the oil tank through the first oil inlet pipe. The driving gear is rotatably supported above the oil tank. The driven gear is meshed with the driving gear and is rotatably supported above the oil tank. The spray nozzle is communicated with the other end of the oil tank through the second oil inlet pipe. The spray nozzle is supported between the driving gear and the driven gear and is used for spraying a lubricant in the oil tank into a meshing part of the driving gear and the driven gear.
