Problems solved by technology

[0003] In the existing design, the tooth poles on the stator are all square, which cannot effectively deal with the torque harmonics generated in the intervening gap where the coil winding is installed, so that the motor using it will have a sense of frustration during operation. And it produces noise. For the stator of the existing design, the stator with inclined tooth poles is generally made by CNC machine tools. However, after a long time, the daily production quantity is very small, and the purpose of mass production cannot be achieved.

Embodiment 1

[0018] As described below, as Figure 1 to Figure 2 As shown, the main components used in this embodiment are described as follows:

[0019] A ring-shaped stator with inclined tooth poles 2. The stator includes a plurality of punches 1 with a plurality of teeth 21 arranged radially, and on the outer wall of the teeth 21 are provided to connect the teeth 21 in sequence Each yoke 211 has a notch 212 separating the yoke 211; a plurality of the punches 1 are stacked and arranged closely to form the annular stator, and each punch 1 from bottom to top is pressed one by one Rotating in a fixed direction makes the corresponding teeth 21 of each punching piece 1 misaligned. Each vertically correspondingly arranged tooth 21 on the stator is stacked to form a tooth seat 25, and both sides of the tooth seat 25 form a slope. 22. At the same time, a plurality of yokes 211 are superimposed to form a wide portion 23, the slots 212 between the yokes 211 constitute a skew slot 24, and the tooth ba...

Embodiment 2

[0027] Such as Figure 3 to Figure 4 As shown, the second embodiment has the same reference numerals as the first embodiment.

[0028] In the second embodiment:

[0029] A ring-shaped stator with inclined tooth poles 2. The stator includes a plurality of punches 1, each of which has a reference ring 4, and the teeth 21 are arranged radially outward from the reference ring 4. The outer wall of 21 has a magnetic yoke 211 that connects the teeth 21 in sequence, and there is a slot 212 between each magnetic yoke 211 that separates the yoke 211; a plurality of the punching sheets 1 are stacked and arranged closely to form the stator, The upper punching pieces 1 rotate in a fixed direction, so that the corresponding teeth 21 of each punching piece 1 are misaligned. Each vertically correspondingly arranged tooth 21 on the stator is stacked to form a tooth seat 25, and A slope 22 is formed on both sides of the tooth seat 25, and a plurality of yokes 211 are superimposed to form a wide po...

Abstract

The invention discloses an annular stator having a slanted tooth pole. The stator comprises a plurality of punching pieces. Each punching piece has a plurality of radially arranged teeth. Magnet yokesare arranged on the outer walls of the teeth and successively connect the teeth. Notches for separating the magnet yokes are arranged between the magnet yokes. The plurality of punching pieces are stacked in close contact with each other to form the stator. The punching pieces are rotated in a fixed direction from top to bottom such that the corresponding teeth on the respective punching pieces are misaligned. The vertically correspondingly arranged teeth on the stator are stacked to constitute a tooth holder. Both sides of the tooth holder form slope surfaces. The plurality of magnet yokes are superposed to form a wide portion. The notches between the magnetic yokes constitute a slanted slot. The tooth holder and the magnetic yokes constitute a single tooth pole in the stator. The objectof the invention is to provide an annular stator having a slanted tooth pole. The punching pieces are used as a basic structure and are stacked on each other and fixed at an angle. The annular statoris simple in structure and contributes to manual operation.

Description

Technical field [0001] The invention relates to the technical field of motors, and in particular to an annular stator with inclined tooth poles. Background technique [0002] The stator is a fixed part of the motor, which is installed with coil windings, through which a rotating magnetic field is generated to drive the rotor to rotate. [0003] In the existing design, the tooth poles on the stator are all quadrangular, and the torque harmonics generated in the intervening gap of the coil winding cannot be effectively processed, so that the motor using it will have a sense of frustration during operation. It also generates noise. For stators of existing designs, stators with inclined tooth poles are generally manufactured by CNC machine tools. However, after time has passed, the daily production quantity is very small, and mass production cannot be achieved. Summary of the invention [0004] The purpose of the present invention is to provide a ring-shaped stator with inclined tooth ...
