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 key fixing methods between the rotor and the magnetic poles is to use screws or glue to fasten the rotor, resulting in The strength 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

Abstract

The invention discloses a double-side attaching Ding's rotor by using opposite poles. The double-side attaching Ding's rotor by using opposite poles are locked mutually by using powerful suction of the opposite poles on the upper and lower surfaces, and fastening is realized without using bolts or glue; the rotor strength and quality of the motor are greatly improved, so that the production and manufacturing are simplified, modularization and standardization are realized, the production efficiency is improved greatly, large-scale industrial production requirement is met, and the cost is reduced greatly.

Description

technical field [0001] The invention relates to the field of motors and the field of power 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 key fixing methods between the rotor and the magnetic poles is to use screws or glue to fasten the rotor, resulting in The strength is not enough, the screws are easy to loosen, damage the stator, etc., so that this kind of high-efficiency energy-saving motor is difficult to be applied and popularized. Contents of the invention [0003] In order to solve the above problems, the present invention provides a Ding rotor with double-sided bonding of opposite-sex magnetic poles, which uses the strong suction force of the upper and lower magnetic poles to ...
