Magnetic levitation blower
Product Introduction
Working Principle
The magnetic levitation compressor is a new type of high-efficiency, energy-saving, and environmentally friendly product that integrates active magnetic levitation bearing technology and high-speed permanent magnet synchronous motor technology.
The active magnetic levitation bearing system is the core system of the magnetic levitation compressor. The motor rotor is fixed between two radial magnetic bearings and two axial magnetic bearings. The rotor's position is detected by a position sensor, which sends the position signal to the magnetic bearing controller in real time. When the rotor deviates, the controller adjusts the magnetic force of each degree of freedom of the magnetic bearings according to the amount of rotor deviation, allowing the rotor to return to the correct position.
