The Doppelmayr Sector Drive (DSD) is a permanent magnet synchronous motor developed by Doppelmayr. It has a long and successful track record and uses cutting-edge frequency converter technology. The drive comprises four or eight independent sectors, depending on output. It is mounted on a two-stage planetary gear unit. Thanks to the independent sectors, limited operation is possible at the press of a button in the event of motor or converter failure. The DSD is comparatively lightweight, achieves a very high level of efficiency and is also ideally suited to steep ropeways and to all installation types.

The DSD motor is water-cooled, which makes it suitable for ecofriendly heat recovery.

Benefits:

• Very high efficiency
• Suitable for every ropeway geometry (even very steep installations)
• Limited operation possible without additional measures in the event of motor/converter failure
