Elevator Gearless Traction Machine Load 630kg Lift parts Speed 1~1.75m/s
The gearless traction machine represents a revolutionary advancement in elevator technology, offering superior efficiency, reliability, and energy savings compared to traditional geared systems. By eliminating the need for a gearbox, this machine reduces mechanical complexity, minimizes maintenance requirements, and enhances performance in modern high-rise buildings.
How It Works
A gearless traction machine operates using a permanent magnet synchronous motor (PMSM) directly connected to the sheave (drive wheel). The motor’s rotor is mounted on the sheave, allowing for smooth, direct power transmission to the elevator ropes. This design eliminates energy losses associated with gear friction, resulting in higher efficiency (up to 85-90%) and quieter operation.
Key Advantages
-
Energy Efficiency – Consumes 20-30% less power than geared machines due to reduced mechanical losses.
-
Space-Saving – Compact design allows for smaller machine rooms or even machine-room-less (MRL) installations.
-
Low Maintenance – Fewer moving parts (no gears or oil changes) reduce long-term servicing costs.
-
Smooth & Quiet Ride – Direct drive ensures vibration-free operation, improving passenger comfort.
-
Longer Lifespan – High-quality permanent magnets and minimal wear extend operational life.
Applications
Gearless traction machines are ideal for:
-
High-speed elevators (≥2.5 m/s) in skyscrapers.
-
Green buildings seeking LEED certification due to energy savings.
-
Modern office & residential towers requiring silent, reliable vertical transport.

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.
