Problems solved by technology

Axial flux motors have gained more and more attention due to their compact structure, high efficiency, and high power density. However, one of the most critical methods of fixing the rotor and magnetic poles is to use screws or glue. The strength of the rotor is not enough, the screws are easy to loosen, damage the stator, etc., making it difficult to popularize this kind of high-efficiency energy-saving motor

Embodiment Construction

[0010] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, the permanent magnet poles of the motor of the present invention are composed of a pole body (2) with a shape (1). The shape of the shape (1) is designed according to the specific requirements of the motor and the use environment of the motor. The pole body ( 2) is a permanent magnet magnetic material, the top surface of the pole body (2) is the air gap surface (3), the bottom surface of the pole body (2) is the bonding surface (4), and the bonding surface (4) is the pole body (2) A surface that can be bonded together with another magnetic pole of the opposite sex by utilizing the strong suction force of the magnetic pole of the opposite sex. There is a digging position (5) on the outer edge of the bonding surface (4). The digging position (5) is mainly convenient for the magnetic pole to Fixing and avoiding on the rotor bracket, the rotor bracket uses the strong suction force of the upper and lo...

Abstract

The invention discloses a permanent magnet pole of a motor. The permanent magnet pole of the motor is simple in structure, is matched with a rotor bracket in use, can enable the rotor strength of an axial magnetic flux motor to be improved significantly and the like, simplifies, modularizes and standardizes the production and manufacturing, significantly improves the production efficiency, satisfies large-scale industrial production requirements, greatly reduces the cost, and can enable the high-efficiency energy-saving motor to be quickly applied and popularized.

Description

technical field [0001] The invention relates to the field of motors and the fields of power generation such as wind power generation and hydropower generation. Background technique [0002] As energy saving and emission reduction are getting more and more attention around the world, one of the most important motor links is indispensable. Axial flux motors have gained more and more attention due to their compact structure, high efficiency, and high power density. However, one of the most critical methods of fixing the rotor and magnetic poles is to use screws or glue. The strength of the rotor is not enough, the screws are easy to loosen, damage the stator, etc., so that it is difficult to popularize the application of this kind of high-efficiency energy-saving motor. Contents of the invention [0003] In order to solve the above problems, the present invention provides a permanent magnet pole of the motor, which has a simple structure and can be used in conjunction with t...
