Doppelmayr Direct Drive - DDD

The Doppelmayr Direct Drive (DDD) is a gearless drive concept, which makes it particularly low-vibration and low-noise as well as energy-efficient and maintenance-friendly. The low weight of the individual components used in the modular ring construction make the drive suitable for helicopter installation. It can also be transported using a standard truck.

The DDD uses a hermetically sealed permanent magnet synchronous motor, which is water-cooled. This enables ecofriendly heat recovery. The incorporation of water cooling also dispenses with loud fan noise, which has a very positive impact on the environment. In direct comparison, the DDD has the lowest noise emissions – it is whisper-quiet. The continuous stator windings are encapsulated in special epoxy resin to provide perfect protection against external influences.

As this drive concept does not require a gear unit, no gearbox oil is required and the associated maintenance costs no longer apply.

Benefits:

  • Exceptionally low noise emissions
  • Exceptionally low maintenance requirement as there is no gear unit
  • Very high efficiency
