    摘要： There is provided an electrical machine 25 comprising: a rotor 37 at least partially disposed within a rotor chamber 31, 48; a stator core 29, 50 coaxially arranged with the rotor chamber 31, 48; and a stator sleeve 27, 40, 80. The stator sleeve 27, 40, 80 is annular and is positioned between the stator core 29, 50 and the rotor chamber 31, 48. The stator sleeve 27, 40, 80 comprises a magnetic material having a relative permeability of at least 10 and an intrinsic coercivity no greater than 1 kAm-1.

    摘要： 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.
