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.
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 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.
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.
- No mechanical contact between surfaces
- No friction
- No wearing
- No oil lubrication
- Vibration free operation
- Continuous rotor balancing monitoring
