Xinda DIANA 4 Gearless Elevator Traction Machine

The Xinda DIANA 4 gearless elevator traction machine is developed for modern lift projects where energy efficiency, smooth ride quality and reduced maintenance are key requirements. Its permanent-magnet synchronous motor design eliminates the conventional gearbox, helping reduce mechanical losses, vibration and operating noise. The machine is suitable for new elevator installations and modernization projects in residential buildings, hotels, offices and commercial facilities. Depending on the final project configuration, it can be used in machine-room-less or compact machine-room layouts with rope traction arrangements selected by the elevator designer. For Nazar Elevator projects, this model can be offered as part of a complete elevator package together with cabin, door, controller and safety components. Final load, speed, sheave, brake voltage and encoder selection should always be confirmed with the official Xinda data sheet and the project calculation.

What is a gearless traction machine?

The Xinda DIANA 4 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 Xinda DIANA 4 to elevator contractors and distributors worldwide.
