  • the present invention relates to a machine comprising a frame containing at least one functional element and a control unit, and equipped with an air compressor, and more particularly a high speed air compressor.
  • the fluid compressors fitted to such machines are generally called turbochargers or centrifugal compressors. They are fitted with a stator and a rotor forming a permanent magnet synchronous motor (brushless motor). Compressors of this type can reach very high speeds, for example 100,000 to 500,000 revolutions / minute. The engine drives the turbine at high speed, the turbine compressing the fluid.
