Embodiment Construction

[0016] Refer to attached figure 1 to attach Figure 8 , the present invention is a kind of motor housing structure, comprises housing main body 1, and housing main body 1 is thin-walled design, and the design thickness of housing main body 1 is only determined by the mechanical performance (strength and rigidity) of housing, rather than as The design of the yoke in the magnetic circuit is determined. The main body of the casing 1 is provided with a yoke insert 2. The thickness constitutes the design thickness of the yoke in the magnetic circuit, and the yoke insert 2 is provided with a positioning boss 3 and a magnetic tile clamping edge 4 for fixing the magnetic tile. As a specific embodiment of the present invention, the yoke insert 2 is provided with two opposite positioning bosses 3, and the yoke insert 2 on the side corresponding to each positioning boss 3 is close to the half-ring position Four magnetic tile clamping edges 4 are respectively provided, and two groups ar...

Abstract

The invention discloses a motor casing structure with material saving, which comprises a casing main body (1). The casing main body (1) is provided with a thin wall, and is provided with a yoke embedding sleeve (2) which is tightly matched with the casing main body (2). The yoke embedding sleeve (2) is provided with a positioning boss (3) and magnetic shoe clamping edges (4) for fixing a magneticshoe.

Description

technical field [0001] The invention relates to a motor casing structure. Background technique [0002] The role or function of the general permanent magnet DC motor casing: one is as a magnetic tile and armature shaft bearing fixture, and the other is as a yoke in the magnetic circuit, that is, as a part of the magnetic field line path of the motor magnetic circuit, so the permanent magnet DC motor The casings are made of soft magnetic materials, because they are easy to magnetize and demagnetize, and have high magnetic permeability, which can play a good role in gathering the magnetic force lines, so they are widely used as the passage of the magnetic force lines, that is, as magnetic The yoke of the road. Generally, the thickness of the casing is determined by the casing as the yoke in the magnetic circuit. When the motor is working, the casing acts as a part of the magnetic circuit and plays a good role in gathering the magnetic force lines. Through the magnetic flux, t...
