INTRODUCTION
Compressor is a device used for creating high pressure.
Conventional type of compressor works with roller bearing and hydrodynamic bearing
Therefore they require lubrication
The frictionless compressor technology is compressor with the application of magnetic bearings and permanent magnet synchronous motor
Permanent magnet brushless synchronous motor has permanent magnet instead of copper windings.
HOW ARE THEY DIFFERENT?
They Are Different because:-
* Magnetic bearings.
* Oil-free design.
* VFD control.
* Smaller and lighter than conventional compressors
MAGNETIC BEARINGS
No friction. This can improve energy efficiency by 2-4%.
Run at high speeds (up to 48,000 RPM) and give good speed control.
Magnetic-bearing compressors offer economic, energy and environmental benefits.
