Description

Magnetic steel stopping structure of brush motor stator
Technical Field
The utility model relates to the technical field of electric machines, especially, relate to a brush motor stator magnet steel locking structure.
Background
There is brush motor stator magnet steel position to need arrange corresponding structure usually and fix a position it, the utility model aims at providing a there is brush motor stator magnet steel retaining structure to keep the magnetic field degree of accuracy.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a there is brush motor stator magnet steel locking structure, it can conveniently fix a position the magnet steel position, keeps the magnet steel degree of accuracy.
The utility model provides a there is brush motor stator magnet steel locking structure, it include the casing and install in magnet steel in the casing, be provided with the retainer in the casing between the adjacent magnet steel, this retainer includes the arc lateral surface part with the contact of casing inner wall, is the medial surface part of V type, two tip of retainer are provided with the locking recess that matches with the magnet steel appearance.
Further, the stop groove is a V-shaped groove.
Furthermore, a guide bulge is arranged on one side of the arc-shaped outer side surface part facing the inner wall of the machine shell.
Further, the cross section of the guide protrusion is triangular.
Compared with the prior art, the beneficial effects of the utility model are as follows: the structure can conveniently position the magnetic steel, so that the accuracy of a magnetic field can be ensured, and the performance of the motor and the consistency of products are greatly improved.

Detailed Description
The present invention will now be described in more detail with reference to the drawings, in which preferred embodiments of the invention are shown, it being understood that one skilled in the art could modify the invention herein described while still achieving the beneficial effects of the invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.
Example 1: as shown in fig. 1-3, the utility model discloses a brush motor stator magnet steel locking structure, it includes casing 1 and install in magnet steel 2 in the casing, in this embodiment, two arc magnet steel 2 have been arranged in the casing, be provided with stopper 3 in the casing between the adjacent magnet steel, this stopper adopts 65 Mn's manganese steel.
Referring to fig. 3, the stopper includes an arc-shaped outer side surface portion 3a contacting the inner wall of the casing and a V-shaped inner side surface portion 3b, and both end portions of the stopper are provided with stopper grooves 3c matching the outer shape of the magnetic steel, for example, the stopper grooves 3c are V-shaped grooves as shown in fig. 3.
And the retainer is integrally formed, and the retainer can fall into the space between the two magnetic steels just positioned in the shell when the retainer is required to be installed.
The stop piece is used as a stop spring piece, and can effectively position and fix the magnetic steel.
The utility model discloses an installation as follows: the original spring is inserted before the magnetic steel is fixed, and then stamping force is applied to the middle of the spring to deform the spring (in the state shown in figure 1), so that the magnetic steel is fixed.
Example 2: this embodiment is different from embodiment 1 in that the arc-shaped outer side surface portion 3a is provided with a guide projection 4 on the side toward the inner wall of the housing, which can mount the stopper 3 at a predetermined position. Correspondingly, a stop piece 3 sliding groove matched with the guide protrusion is required to be arranged on the inner wall of the shell, and the problem that the stop piece moves along the circumferential direction of the side wall of the shell can be avoided when the stop piece is installed in place.
As can be seen in fig. 4, the guide projection is triangular in cross-section. In the case of mounting the stoppers 3 in the casing, however, it is possible to select only one of the stoppers to be arranged with the guide projection and the other stopper to be provided with no guide projection.
The above description is only for the preferred embodiment of the present invention, and does not limit the present invention. Any technical personnel who belongs to the technical field, in the scope that does not deviate from the technical scheme of the utility model, to the technical scheme and the technical content that the utility model discloses expose do the change such as the equivalent replacement of any form or modification, all belong to the content that does not break away from the technical scheme of the utility model, still belong to within the scope of protection of the utility model.
