Turbo-alternator

 Revolutionary twin micro- turbine hermetic turbo-alternator and high efficiency regenerative IGBT drive

 

  • Turbo-alternator only 300mm diameter/600mm long
  • 200kWe PM alternator on common shaft to the turbines-no coupling losses
  • Two 45,000 rpm high speed radial turbines on a single shaft
  • Gas "foil" bearing technology- none contact for long life
  • Eliminates ancillary equipment associated with lubricated or magnetic bearing systems
  • Much wider temperature range than other bearing systems
  • Alternator is non-sychronously coupled to the grid allowing for wide turn-down necessary for varying waste heat sources 
  • Easily cascaded to increase the overall generation capacity
  • Working fluid cooled stator-no ancillary stator cooling equipment
  • High speed IGBT regenerative drive provides for complete control of the turbo-alternator 

                                                                                   

 

 

The turbo-alternator is closely managed by the electronic drive. The drive "learning" the characteristics of the alternator.
