The principle of magnetic levitation

The magnetic bearing is controlled by the internal magnetic bearing, and the magnetic field is generated by the electric current, and the suction force is generated by the magnetic field at the same time, so as to realize the suspension of the rotating shaftThe magnetic levitation blower adopts non-contact, non-mechanical friction magnetic levitation bearing and high-speed and high-power permanent magnet synchronous motor to directly drive the high-efficiency fluid impeller, which overcomes the shortcomings of traditional blowers and air-suspended blowers, and has the advantages of high efficiency, low noise, less fault, and no lubrication system
