Problems solved by technology

The structure of the above scheme is too bloated and relatively complicated, which indirectly increases the cost
[0006] The existing variable speed permanent magnet coupling needs to manually disassemble the bolts and gaskets to change the air gap, thereby changing the transmission torque and output speed, and the adjustment workload is large and time-consuming
These problems lead to low user acceptance, which is not conducive to the promotion and application of products

Abstract

The invention discloses a permanent magnet coupler with a variable magnet position and a variable speed, and relates to the technical field of permanent magnet eddy current transmission. The permanentmagnet coupler comprises a permanent magnet rotor assembly installed at the load end of a permanent magnet coupler. The permanent magnet rotor assembly is located between a first conductor disc and asecond conductor disc. The permanent magnet rotor assembly comprises a first rotor disc and a second rotor disc which are oppositely and coaxially matched; a coaxial gear ring and a plurality of gearassemblies meshed with the gear ring are installed in the first rotor disc and the second rotor disc. By changing the radial position of the magnet, the action radius of a magnetic field is equivalently changed, so that the transmission torque and the output rotating speed are changed, the adjustment is convenient and fast, the application adaptability is high, and the popularization and application of the variable-speed permanent magnet coupler are facilitated.

Description

technical field [0001] The invention belongs to the technical field of permanent magnet eddy current transmission, in particular to a permanent magnet coupler with variable magnet position and variable speed. Background technique [0002] The permanent magnet magnetic coupling is a new type of transmission device that uses the force of the magnetic field to realize the non-contact transmission of force or torque. The device has the advantages of stable performance, no high-order harmonic pollution, and no electromagnetic interference. [0003] It can be installed between the motor and the load to realize the soft start of the motor, and will not burn the motor coil due to overload. In terms of materials, NdFeB permanent magnet materials with better performance are used as the magnetic source, which greatly improves the transmission power. However, the price of permanent magnet materials with high magnetic energy product is relatively high, resulting in a relatively high co...
