Magnetic Levitation Centrifugal Compressor

The magnetic suspension centrifugal compressor adopts 5-degree-of-freedom magnetic suspension bearing and high-speed permanent magnet synchronous motor technology, eliminating the complex speed-increasing gearbox and lubricating oil system required by traditional compressors, and is 100% oil-free. During operation, the rotor is completely suspended, with no mechanical friction, no transmission loss, low noise, small vibration, long service life, no performance degradation, and 20% energy saving compared to traditional air compressors. The dedicated magnetic suspension controller can monitor the rotor operation status in real time, accurately control the axis position, and ensure the stability of machine operation.
