Abstract

The invention discloses a rotary motor and a rotor assembly thereof. The rotor assembly comprises a first rotor. The first rotor comprises a first central shaft, a first rotor body, a first shaft hole, a plurality of first through hole groups, a plurality of second through hole groups and a first outer edge. The plurality of first through hole groups surround the first central shaft and are arranged at intervals. The plurality of second through hole groups surround the first central shaft and are arranged at intervals. One second perforation group is arranged between two adjacent first perforation groups. A first quadrature axis is defined between the adjacent first through hole group and second through hole group. The first through hole group defines a first straight axis, and the secondthrough hole group defines a second straight axis. The first outer edge includes a plurality of first sections respectively corresponding to a first quadrature axis, a plurality of second sections respectively corresponding to a first straight axis, and a plurality of third sections respectively corresponding to a second straight axis. The plurality of first sections are arranged in a protruding manner relative to the first rotor body. Therefore, the effect of enhancing the reluctance torque is achieved.

Description

technical field [0001] The invention relates to an electrical machine, in particular to a rotating electrical machine and a rotor assembly thereof. Background technique [0002] First of all, in the prior art, under the operation of the motor at high speed and / or high torque, the operation of leading the phase current will be carried out. This operation will make the magnetic force of the rotor push to the next tooth structure on the stator to generate a magnetic resistance torque. [0003] However, in this case, the magnetic flux density is particularly high at the quadrature axis (Q axis) of the magnet because the magnetic force is squeezed and compressed to the next tooth structure on the stator. Therefore, the phenomenon of magnetic saturation is easy to occur, which limits the performance of the motor. [0004] Therefore, in view of this, how to overcome the above-mentioned defects through the improvement of structural design has become one of the important issues tha...
