Wittur WSG-LF.S Gearless Elevator Traction Machine

Wittur WSG-LF.S is a professional elevator traction machine solution for compact MR and MRL systems, new installation and modernization. Developed around Wittur’s gearless synchronous drive concept, the machine is intended for projects where compact installation, ride comfort, low vibration and energy efficiency are critical. It is suitable for new elevator installations and, depending on configuration, modernization projects where the existing machine space or suspension arrangement must be carefully managed. The machine can be combined with compatible inverter drives, encoder feedback and safety brake systems to support precise speed control and stable elevator operation. For Nazar Elevator projects, WSG-LF.S can be positioned as a premium European traction machine option for passenger elevators, hospital lifts, MRL solutions, mid-rise buildings or high-rise applications according to the selected series. Final rated load, speed, sheave diameter, roping, brake voltage and mounting arrangement should always be confirmed from the official Wittur data sheet before quotation and production.

What is a gearless traction machine?

The Wittur WSG-LF.S is a gearless elevator traction machine. A gearless machine couples a permanent-magnet motor directly to the drive sheave, with no gearbox between them — which removes the largest source of energy loss, gear oil maintenance and mechanical noise found in geared systems.

Gearless machines are the standard choice for machine roomless (MRL) elevators and for installations where quiet running and low energy consumption are specified. Nazar Elevator supplies the Wittur WSG-LF.S to elevator contractors and distributors worldwide.
