Elevator Traction Machine

This product is driven by a high-efficiency permanent magnet synchronous motor (PMSM) or induction motor, and has the characteristics of high starting torque, low noise, and compact structure. It is suitable for machine room-less elevators, passenger elevators, sightseeing elevators, freight elevators, and residential/commercial high-rise elevators. It is equipped with a reliable braking system and a high-strength traction sheave to ensure safe and stable operation.

FAQ

1. What is the load range of the traction machine?
Elevator traction machines can cover small home elevators of 320kg to large commercial freight elevators of more than 2000kg. When selecting, the power, traction ratio and braking capacity of the traction machine should be matched according to the elevator's rated load, speed, lifting height and other parameters to ensure stable performance.

2. What is the difference between the traction machine used in machine roomless elevators and traditional traction machines?
The traction machine of a machine roomless elevator is usually compact and installed on the top or one side of the shaft. It requires small size, light weight and low noise. It is often equipped with a permanent magnet synchronous motor and a built-in brake, which is more flexible to install and has higher requirements for structure and safety control.

3. What is the role of the traction machine brake?
The brake is used to lock the traction sheave after the elevator stops running to prevent the car from sliding. It is controlled by spring pressure braking and power release. It must respond quickly and reliably, especially to provide safety protection in the event of power outages, overspeed or system failure.

4. Do all elevators need a traction machine?
No. Although the traction machine is the core component of most traction elevators, hydraulic elevators and screw elevators use different drive mechanisms and do not use traction machines. However, in commercial buildings, most medium and high-speed elevators use traction structures.
