High speed oil free motocompressor (HOFIM)

A 20000 rpm, 2 MW compressor, directly driven by an induction motor, has been developed and successfully tested. The induction motor is fed by a variable frequency connecter at a frequency of 333 Hz. The shaft line is supported by 5 (4 radial, 1 thrust) magnetic bearings with digital control, making the system completely oil free. The benefits of the technology are low maintenance cost, reduced installation time and high overall efficiency.
