Permanent Magnet Synchronous Gearless Traction Machine For Elevator

Elevator Permanent Magnet Synchronous Gearless Traction Machine for elevator parts

Introduction

The Permanent Magnet Synchronous Gearless Traction Machine (PMSGTM) is a highly efficient motor system used in modern elevators, replacing traditional geared traction systems. It offers superior energy efficiency, smoother operation, and reduced maintenance, making it the preferred choice for high-rise buildings and smart elevators.

Working Principle

The PMSGTM operates using a permanent magnet rotor and a stator with windings, eliminating the need for gears. When an electric current passes through the stator, it generates a rotating magnetic field that interacts with the permanent magnets, producing torque to move the elevator car.

Key Advantages

1. High Efficiency (Up to 90-95%) – No gear losses, reducing energy consumption by 30-50% compared to geared systems.

2. Compact & Lightweight Design – Eliminates bulky gearboxes, saving space in machine rooms.

3. Smooth & Quiet Operation – Reduced mechanical friction and vibration enhance passenger comfort.

4. Low Maintenance – Fewer moving parts decrease wear and tear, lowering long-term costs.

5. Regenerative Braking – Converts braking energy into electricity, feeding it back into the building’s power grid.

Applications

• High-speed elevators in skyscrapers

• Mid-to-high-rise residential and commercial buildings

• Smart and IoT-enabled elevators

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.
