The high-temperature magnetic pump changes the internal magnetic rotor in the synchronous magnetic drive pumps in the FSOM, FPIM, FAYM and other series to a squirrel-cage rotor (industrial pure iron plus copper bar) similar to the asynchronous motor, which becomes the FGWM asynchronous magnetic drive high-temperature magnetic force Pump.

FGWM series belongs to asynchronous magnetic drive high temperature magnetic pump (temperature resistance ≥450℃), the design is based on the principle of electromagnetic induction, and is inspired from the structure of asynchronous motor and permanent magnet motor, etc., the internal magnetic rotor of the existing magnetic coupling Changed to a squirrel-cage rotor similar to an asynchronous motor, the outer rotor structure is basically unchanged. During operation, the external rotor of the coupling is driven to rotate by an external motor, and a rotating magnetic field is generated on the inner side. Under the action of the rotating magnetic field, an induced current is generated in the inner rotor, which in turn generates electromagnetic torque to rotate the inner rotor. This type of magnetic coupling uses electromagnetic induction to transmit torque. During operation, there is always a speed difference between the inner and outer rotors, so it can be called an induction asynchronous magnetic coupling.

The coupling does not require permanent magnetic materials on the inner rotor, so there is no problem of demagnetization caused by high temperature. This new type of high temperature resistant magnetic coupling works reliably, and the production cost is further reduced. At the same time, the maintenance is convenient and the service life will be extended. . Successfully solved the failure problem of the current magnetic coupling due to the demagnetization of the internal magnetic steel.
