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

[0011] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 As shown, the opposite-sex magnetic poles of the axial flux motor of the present invention are double-sidedly bonded to the rotor bracket. The air gap body (1) and the power transmission body (2) are connected through the coupling body (3), and the air gap body (1) has Evenly distributed hollowing positions (4) according to the shape of magnetic poles, the number of hollowing positions (4) = number of motor pole pairs * 2, angle a = 360 degrees / (number of motor pole pairs * 2), in the hollowing position (4) There are convex shoulders (5) connected inside, and the processed magnetic poles are put into the hollowed out position (4) from the upper and lower sides in the way of bonding the opposite sides of the magnetic poles, and the convex shoulders (5) respectively clamp and position the upper and lower magnetic poles, so that The strong suction force of the upper and lower magnetic poles ...

Abstract

A magnetic pole of an axial flux motor is double-sided attache to a rotor bracket, A magnetic pole-opposite double-side laminate rotor bracket of that axial flux motor can greatly increase the rotor strength of the axial flux motor, simplify the production and manufacture, modularize and standardize the production, greatly improve the production efficiency, meet the requirement of large-scale industrial production and greatly reduce the cost, so that the high-efficiency energy-saving motor can be rapidly applied and popularized. The rotor bracket of the axial flux motor with the magnetic pole-opposite double-side laminate rotor bracket of the axial flux motor can greatly increase the rotor strength, simplify the production and manufacture, modularize and standardize the production.

Description

technical field [0001] The invention relates to the field of high-efficiency and energy-saving motors and the fields of high-efficiency 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 method that can greatly increase the strength of the...
