Elevator Lift Parts Gearless Traction Machine With 400mm Sheave

The gearless traction machine represents the most advanced drive technology in modern elevator systems, offering superior efficiency, reliability, and compactness compared to traditional geared machines. By eliminating the need for a gearbox, it directly couples the motor to the drive sheave, reducing energy losses, mechanical wear, and maintenance requirements.

This system typically uses a permanent magnet synchronous motor (PMSM) with a high-precision variable frequency drive (VFD), ensuring ultra-smooth acceleration, precise floor-leveling, and optimal energy consumption. The absence of gears allows for near-silent operation, making it ideal for high-end residential, commercial, and high-rise buildings.

Key features include:

• Higher Efficiency: Energy savings of up to 30-50% compared to geared systems, with regenerative drives feeding excess power back into the building grid.

• Compact & Lightweight: Reduced footprint enables installation in small machine rooms or even within the hoistway (machine-room-less configurations).

• Low Maintenance: Fewer moving parts decrease wear and extend service life.

• Superior Performance: Capable of high speeds (up to 20 m/s) with exceptional ride comfort.

Gearless traction machines comply with global safety standards (EN 81-20/50, ASME A17.1) and are increasingly integrated with IoT-based predictive maintenance systems for real-time monitoring. Their advanced design makes them the preferred solution for modern, sustainable, and high-performance elevator applications.

FAQ
1. Are the elevator wire ropes durable?
The elevator wire rope has special provisions and requirements. Configuration is not only for wire rope and rated load, but also considered the size of the traction, as a result, the tensile strength of wire rope is greater than the weight of the lift. The safety factor is equipped with more than four wire rope. So it won’t break at the same time.
2. Is it dangerous for power failure suddenly during the elevator running?
If it occurs, the elevator will automatically stop due to the electrical and mechanical safety device. In case of power failure,elevator brakes will automatically taken. In addition, the power supply departments such as planned outage, prior notice are also operating.
3. Will us be hurt when it closed suddenly?
In the closing process, if people touch the hall door, the door of elevator will automatically restart without any danger. With anti clamping switch, once the gate touched, this switching action make the elevator unable to be closed and even reopened. In addition, closing force is also available here.
4. How the elevator running?
Elevators are operated with a counterweight wire rope through the (tractor) traction drive, making ups and downs on the guide rail.
5. Is the escalator installation complicated?
We believe the functions of an escalator are not necessarily proportional to the operation complexity. Therefore, escalators designed by us apply an integrated structure, so that the equipment is more precise and more efficient and allows easier and more convenient commissioning.
6. Do you have any cerifications?
Yes, we do with ISO9001 / CCC / CE Certificates for u.
