Embodiment Construction

[0010] As shown in the figure, a new high temperature resistant solid rotor asynchronous magnetic coupling design method of the present invention includes the proposal of a common solid rotor magnetic coupling, magnetic circuit design and magnetic circuit calculation.

[0011] The proposal of the ordinary solid rotor magnetic coupling works by arranging permanent magnets on the inner and outer rotors respectively, and using the principle that the magnets of the same sex repel each other and the opposite sexes attract each other. The permanent magnets are arranged on the inner and outer rotors of the magnetic coupling shaft. At present, the third-generation rare earth permanent magnet NdFeB magnets are generally used. The residual magnetic induction and coercive force of this rare earth permanent magnet material NdFeB are much higher than other magnetic materials.

[0012] The magnetic circuit design includes the selection of magnetic pole arrangement, the determination of the t...

Abstract

The invention discloses a design method of a novel high-temperature-resistant solid rotor asynchronous magnetic coupling. The method is a new type of non-contact electromagnetic induction power transmission device developed in recent years. Rare earth permanent magnets are arranged on the inner side of the outer rotor of the coupling. . The internal rotation adopts a solid rotor and does not require permanent magnet materials. The high-temperature-resistant asynchronous solid-rotor magnetic coupling designed by sample selection effectively solves the problem that the previous magnetic-drive pumps cannot transport high-temperature media, and has high economic value and good application prospects. The design and analysis of the magnetic circuit of the magnetic coupling is an important basis for solving the electromagnetic torque of the magnetic coupling. It is necessary to optimize the design of the magnetic circuit, so the present invention selects the magnets to be closely arranged for magnetic concentration, and derives the magnetic permeability and magnetic flux leakage system, which has good practicability and has very important reference value for the research of green machinery.

Description

technical field [0001] The invention belongs to the field of magnetic transmission, and in particular relates to the design of a novel high-temperature-resistant solid rotor asynchronous magnetic coupling. Background technique [0002] Environmental problems are one of the three major problems facing human society in the 21st century, which seriously threaten the survival and development of human society. The main factors causing environmental pollution are related to the leakage generated during the operation of mechanical equipment. In order to control the further deterioration of the environment, scholars "Green technology" has been put forward one after another. Develop green environmental protection machinery products to reduce environmental pollution. Non-leakage pumps widely used in petroleum, chemical, pharmaceutical and other industries are well adapted to this development trend. The main feature of non-leakage pumps - magnetic pumps is the successful use of high-t...
