Abstract

The invention provides a sleeve magnetism-gathering magnetic circuit structure used for a permanent magnetism eddy transmission apparatus, and belongs to the field of permanent magnetism transmission technologies. Compared with a sleeve permanent magnetism eddy transmission apparatus adopting a discrete magnetic circuit structure, a torque or the transmission power generated by permanent magnetism material per unit mass are bigger according to a sleeve permanent magnetism eddy transmission apparatus adopting the magnetic circuit structure provided by the invention. The magnetic circuit structure includes a permanent magnet rotor used as a first outer rotor and a vortex ring rotor used as a first inner rotor, each first permanent magnet set is composed of 2 to 5 magnets which tightly contact together, directions of the magnetizing magnetic polarities of magnets in the same first permanent magnet set are same, and directions of the magnetizing magnetic polarities of magnets of adjacent first permanent magnet sets are different. The magnetic circuit structure includes a vortex ring rotor used as a second outer rotor and a permanent magnet rotor used as a second inner rotor, each second permanent magnet set is composed of 2 to 5 magnets which tightly contact together, directions of magnetizing magnetic polarities of adjacent magnets in the same second permanent magnet set are same, and directions of the magnetizing magnetic polarities of adjacent second permanent magnet sets are different.

Description

technical field [0001] The invention belongs to the technical field of permanent magnet transmission, and in particular relates to a sleeve-type magnetism-concentrating magnetic circuit structure for a permanent magnet eddy current transmission device. Background technique [0002] Permanent magnet eddy current transmission technology originated from the improvement and development of permanent magnet synchronous transmission technology. When the early permanent magnet synchronous seal drive technology was applied to equipment such as magnetic pumps and magnetic drive agitators, it often encountered unfavorable conditions such as frequent decoupling due to high temperature, corrosion or overload, which may lead to The permanent magnet on the rotor is destroyed, demagnetized and other problems. In order to solve this kind of problem, the eddy current ring technology came into being. Its basic structure is to remove the permanent magnet on the driven rotor and replace it with...
