Good Quality Elevator Traction Machine For Lift Motor Traction
Machine
The Elevator Traction Machine is the core driving component of a traction elevator system,
responsible for lifting and lowering the elevator car via steel
ropes or belts. It operates on the principle of friction between
the sheave (drive pulley) and the suspension ropes, ensuring smooth
and efficient vertical transportation.
Modern traction machines are typically powered by permanent magnet synchronous motors (PMSM) or gearless AC/DC motors, offering high energy efficiency, reduced noise, and minimal
maintenance compared to traditional geared systems. The machine
consists of a motor, brake, drive sheave, and encoder, all housed
in a compact and robust structure.
Key advantages include:
Energy Efficiency: Regenerative drives recover energy during descent, reducing power
consumption.
Precision Control: Variable frequency drives (VFDs) ensure smooth acceleration and
deceleration, enhancing passenger comfort.
Space-Saving Design: Gearless traction machines eliminate the need for large gearboxes,
making them ideal for high-rise buildings with limited machine room
space.
Durability: High-quality materials and advanced manufacturing techniques
ensure long service life.
Traction machines are classified into geared (for mid-rise applications) and gearless (for high-speed elevators). They comply with international safety
standards such as EN 81-20/50 and ASME A17.1, ensuring reliable and safe operation.
With advancements in smart technology, modern traction machines
integrate IoT-enabled monitoring for predictive maintenance,
further improving efficiency and uptime. Their superior performance
makes them the preferred choice for commercial, residential, and
high-speed elevator systems worldwide.

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.
