  • 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: 11615130
    Abstract: A core data-based storage method for radial multidimensional documents according to an embodiment includes classifying first documents with same document type information into a preset folder to obtain a classified folder; acquiring the total number of levels of document level information of all non-core documents; and displaying preset target images at core display positions and/or non-core display positions, and setting a corresponding storage link path for each of the displayed preset target images. The documents may be stored by classification and displayed visually.

  • Patent number: 11091926
    Abstract: A building earthquake resistance structure includes an integrally connected roof support frame, used for supporting a roof of a building independently from walls of the building; a plurality of support columns, fixedly connected to the roof support frame; an annular trench, arranged in the ground around the building; an annular damping frame, arranged within the annular trench, lower ends of the support columns being fixedly connected to the annular damping frame; a plurality of dampers, arranged between a bottom portion of the annular trench and the annular damping frame. An earthquake resistance method for the building earthquake resistance structure prevents damage caused by the roof collapsing during an earthquake by supporting the roof of the existing building in the ground via the support columns. The building earthquake resistance structure is easy to construct and suitable for transforming traditional old buildings.
