BRUSHED PERMANENT MAGNET MICROMOTOR AND ASSEMBLY METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/214558
Kind Code:
A1
Abstract:
Disclosed are a brushed permanent magnet micromotor and an assembly method therefor. An upper stator support and a lower stator support of the brushed permanent magnet micromotor are in design whereby same are fitted together, wherein recessed parts of the upper stator support and the lower stator support are fitted together to form an integrated installation cavity for installing a motor shaft, an iron core winding, bearings, and a commutator. During installation, the iron core winding, the bearings and the commutator are first installed on the motor shaft to form a rotor assembly, the rotor assembly is then installed in the recessed part of the lower stator support, and finally, the upper and lower stator supports are fitted together and fixed, with brushes being placed at brush installation positions. Such a structure makes the assembly of the motor simple, and can achieve quick assembly. Moreover, the two bearings are fixed to or compressed on the same part, thereby guaranteeing the concentricity and coaxiality of the two bearings, avoiding compression from a central deflecting force during assembly, avoiding the problem of same being embedded into a case, and making assembly simple.
