High speed electric motor

Air cooled variable speed high frequency electric motor. The impeller and the motor cooling fan are mounted directly to the motor shaft. Vertically mounted motor with magnetic bearings and variable rotation speed.
Frequency converter In-built frequency converter for variable motor speed control and optimal efficiency at all operation points. Start-up with soft start function. Including Rfi-filter that filters the radio frequency interference emitted by the frequency converter.

Impeller

Impeller shaped from a solid forged piece of DURAL Aluminium alloy on a numerical machining center in CAM technology. Impeller design with 3 dimensional shaped blades, individually optimized to the design range of the compressor.

Magnetic bearings

Two radial bearings with 8 pole magnets each and two axial magnetic bearing with 2 pole magnets each and continuous rotor position measurement controlled by active magnetic bearing controller. Including Rfi-filter.
