Abstract
The motor rotor assembly structure includes a rotating shaft, a plurality of rotor cores formed by a plurality of rotor punches neatly laminated, and rotor pressure plates installed at front and rear ends of the rotor core. The rotor core is provided with a shaft hole for mounting the rotating shaft in the middle in an axial direction. Two rotor pressure plates press the plurality of rotor punches. The rotating shaft is a hollow shaft. The plurality of rotor punches has the same structure. Each of the rotor punches is provided with a plurality of sets of positioning holes. The plurality of rotor punches is positioned and fixed to the rotating shaft through the plurality of sets of positioning holes to realize oblique poles between rotor segments. The motor rotor assembly structure is made by laminating one type of rotor punches.
