What is the principle of holding a magnetic lifting device

Oct 21, 2017

A simple, labor-saving, easy to manufacture "permanent magnet lifting device with rotary control."

It is composed of two different materials between the long roll in permanent magnet poles of spin finish of the suction or discharge, half of roller is the permeability, the other half is not permeability, in the motor driven by rotation in the arc wall between permanent magnet poles.

Semicircle form magnetic short circuit of permanent magnet poles, for unloading heavy, namely the semicircle permeability material of permanent magnet magnetic open formation, is the holding, this device has simple structure, convenient operation, low fault rate and easy system to save power, technology and knowledge, easy to implement
