When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element.

It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, refer to an orientation or positional relationship illustrated in the drawings for convenience in describing the present application and to simplify description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present application.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

A brushless motor, specifically refer to fig. 1, includes a mounting base 11 with a through hole in the middle, a multi-pole winding stator 21 fixed on the outer surface of the lower end of the mounting base 11 and arranged around the through hole, a rotating shaft 22 with one end passing through the through hole, a housing 23 arranged at the other end of the rotating shaft and with an open upper end, and a permanent magnet rotor 24 fixedly arranged in the housing 23 and wrapping the multi-pole winding stator 21.

The brushless motor is characterized in that after a multi-pole winding stator 21 arranged at the lower end of a mounting seat 11 is electrified, generated magnetic force induces and drives an annular permanent magnet rotor 24 which surrounds the outside to rotate, the annular permanent magnet rotor 24 is fixedly arranged with a shell 23, the middle of the shell is fixed with a rotating shaft 22 which penetrates through the annular permanent magnet rotor 24, and the other end of the rotating shaft 22 penetrates through a through hole of the mounting seat 11. The structure of this application forms a drive mechanism who provides rotary motion, because this product adopts the magnetic field induction principle and does not have the essence contact, and frictional force is little, and speed is high, consequently has the advantage that the noise is low, longe-lived.
