Magnetic suspension refrigeration technology opens a new pattern of air conditioning
With the development of electronic technology, control engineering, signal processing components, electromagnetic theory, new electromagnetic materials and rotor dynamics, magnetic levitation technology has made great progress in recent years.
The magnetic suspension system consists of four parts: rotor, sensor, controller and actuator. The actuator includes electromagnet and power amplifier. Magnetic bearing is a kind of lubrication system which uses magnetic field to suspend the rotor, so that there is no mechanical contact, no mechanical friction and no need for mechanical bearings and mechanical bearings. Using magnetic bearing in refrigeration compressor, all troubles caused by lubricating oil no longer exist. The magnetic bearing technology is applied to the magnetic refrigeration compressor.
