Patents by Inventor Yukun Zhao

Yukun Zhao has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11863109
    Abstract: The application provides a method and device for adjusting a permanent magnet motor, an equipment, and a storage medium. The method includes the following operations. An electronic equipment acquires a counter electromotive force (CEMF) parameter, information of an electromagnetic structure of a permanent magnet motor to be adjusted and a minimum impedance value of any short-circuited coil of the permanent magnet motor to be adjusted, to determine an operational time of the short-circuited coil. The electronic equipment further judges, according to the operational time of the short-circuited coil, whether an adjustment instruction is required to be transmitted to a production equipment. When the operational time is inconsistent with a preset time, the electronic equipment transmits the adjustment instruction to the production equipment. The production equipment adjusts, according to the adjustment instruction, the electromagnetic structure of the permanent magnet motor to be adjusted.

  • Patent number: 11854802
    Abstract: The present invention discloses a super-flexible transparent semiconductor film and a preparation method thereof, the method includes: providing an epitaxial substrate; growing a sacrificial layer on the epitaxial substrate; stacking and growing at least one layer of Al1-nGanN epitaxial layer on the sacrificial layer, wherein 0<n?1; growing a nanopillar array containing GaN materials on the Al1-nGanN epitaxial layer; etching the sacrificial layer so as to peel off an epitaxial structure on the sacrificial layer as a whole; and transferring the epitaxial structure after peeling onto a surface of the flexible transparent substrate. Compared to traditional planar films, the present invention can not only improve the crystal quality by releasing stress, but also improve flexibility and transparency through characteristics of the nanopillar materials.
