Elevator Lift Motor Drive Elevator Traction Machine Permanent Magnet Motor For Elevator

Elevator Traction Machine: The Powerhouse of Vertical Transportation

The elevator traction machine serves as the core driving system in modern elevators, converting electrical energy into mechanical motion to enable safe and efficient vertical transportation. Typically installed in machine rooms or hoistways, these precision-engineered systems utilize either geared or gearless configurations to move elevator cars through friction between steel ropes and a motor-driven sheave.

Key Components & Technologies:

• High-efficiency permanent magnet synchronous motors (PMSM) for gearless models (up to 92% energy efficiency)

• Electromagnetic brakes with fail-safe spring activation (EN 81-20/50 certified)

• Variable Frequency Drives (VFDs) for smooth acceleration/deceleration (0.2 m/s² precision)

• Polyurethane-coated traction sheaves to extend rope lifespan by 30-40%

Performance Advantages:

• Noise levels as low as 45 dB(A) for residential applications

• Compact designs with machine-room-less (MRL) options saving 30% space

• Regenerative drives feeding 15-25% energy back into building grids

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.
