ROTOR ASSEMBLY AND MOTOR HAVING SAME

WIPO Patent Application WO/2021/022959

A1

A rotor assembly (100), comprising a rotor (101) and a rotor winding (102). The rotor (101) is provided with a plurality of teeth; tooth slots are provided between adjacent teeth; the rotor (101) can be connected to a rotor shaft to output power; the rotor winding (102) is composed of coils wound on the rotor (101); the rotor winding (102) comprises a portion extending in an axial direction parallel to the rotor assembly (100) and a portion extending in a plane perpendicular to the axial direction; the portion extending in the plane perpendicular to the axial direction comprises a plurality of sections; in the axial direction, the plurality of sections are in one-to-one correspondence to corresponding sides of two or more polygons, respectively. The winding method can solve the problems such as length difference of copper wires between windings due to sequential superposition of the coils in traditional windings, thus achieving the technical effects of improving the balance of the armature and minimizing the difference in resistance of windings.
