Title:
ROTOR, MOTOR, AND MANUFACTURING METHOD FOR ROTOR
Document Type and Number:
WIPO Patent Application WO/2023/142239
Kind Code:
A1
Abstract:
The present application provides a rotor, a motor and a manufacturing method for a rotor, and relates to the technical field of motors. The manufacturing method comprises: assembling a plurality of plate materials, and permanent magnet elements/rotor coils together to form a rotor preform, each plate material being formed by plate-shaped fiber fabric pre-impregnated with resin, and the shape of the plurality of plate materials satisfying that: the plurality of plate materials, after being aligned and stacked together, can be matched to form a rotor body having a mounting chamber, the mounting chamber being suitable for mounting the permanent magnet elements/rotor coils; and forming a rotor after a sizing step and a curing step. A technical problem of the mass density of a rotor formed by stacking silicon steel plates is solved, and technical effects are achieved that the rotor has a low mass density, and exhibits high tensile strength when rotating at a high speed.
