Detailed ways

It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

In the present invention, unless otherwise stated, the use of directional words such as "upper, lower, top, bottom" is usually for the direction shown in the drawings, or for the vertical, vertical or In terms of the direction of gravity; similarly, for the convenience of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned orientation words are not used to limit the present invention.

A miniature brushless motor as shown in Figures 1-2 includes a main body 1, the main body 1 includes an upper side 2 provided with a circuit board 8 and a lower side 3 opposite to the upper side 2, the upper side 2 and the lower side 3 are on Each is provided with at least two nickel-plated strong magnets 9 .

In this embodiment, the main body 1 is a circular plate structure, and a protective plate 7 of a straight plate structure is provided on the outer side of the main body 1 .

In this embodiment, the body 1 is provided with three bayonet openings 6 along the circumferential direction.

In this embodiment, three nickel-plated ferromagnets 9 are evenly arranged on the upper side 2 , and six nickel-plated ferromagnets 9 are evenly arranged on the lower side 3 .

In this embodiment, three first grooves 4 are arranged on the upper side 2, six second grooves 5 are evenly arranged on the lower side 3, and the first grooves 4 and the second grooves 5 are both provided with nickel-plated strong Magnet 9.

In this embodiment, the body 1 and the protective plate 7 are integrally formed.

Applying the technical solution of this embodiment, by installing nickel-plated strong magnets 9 on the upper side 2 and the lower side 3 of the main body 1, the magnet can be made closer to the magnetic steel, the magnetism is stronger, and its magnetic effect can be better exerted, and ordinary The lower casing assembles the whole machine, which reduces the cost of raw materials and has a wider range of applications.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
