Description

technical field [0001] The invention belongs to the technical field of transmission in mechanical engineering, in particular to a magnetism-gathering magnetic coupler. Background technique [0002] Magnetic couplings are also called magnetic couplings and permanent magnet transmissions. Permanent magnet eddy current transmissions are mainly composed of copper rotors, permanent magnet rotors and controllers. Generally, the copper rotors are connected to the motor shaft, and the permanent magnet rotors are connected to the working There is an air gap between the copper rotor and the permanent magnet rotor, and there is no mechanical connection for torque transmission. [0003] According to CN107276368A, an adjustable-speed magnetic-gathering double-tube asynchronous magnetic coupler, in the present invention, the torque is transmitted through the driving rotor and the driven rotor without contact, avoiding friction, wear and vibration during transmission of the mechanical coup...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the existing technology, although the power transmission is realized through magnetic coupling, it solves the problem that the rotating shaft has no inertial rotation and the load is large during the starting process of the motor. Problem, but the existing magnetic coupler, after the motor starts, the working machine responds slowly, and the working machine needs to rotate for a period of time before the working machine can run normally. At the same time, the transmission ratio between the motor and the working machine cannot be accurately controlled during the rotation process. , during the working process, the rotation speed of the working machine is easily affected by the load and the environment. For the equipment that requires a high speed and uniform speed during normal operation, it cannot be used.
