Types of Elevator Traction Machine


How are large building elevators able to travel up and down buildings smoothly, allowing passengers to get from one floor to another with ease? It’s all due to the complexity of elevator traction systems.

Elevator traction machines use electromechanical power to get your elevator car moving, vertically transporting you safely and smoothly.

Elevator traction manufacturers such as Dazen, are a significant name when it comes to elevator traction technology. Dazen’s elevators are tailored to fit people’s needs, whether it’s residential, commercial, or hospital buildings.

Let’s describe the capabilities of elevator traction machines and how Dazen’s cutting-edge solutions can elevate your vertical transportation experience!

What is an Elevator Traction Machine?

An elevator traction machine, also termed a traction motor, is a crucial component of traction elevator systems, the most common means of elevators used worldwide. Traction systems move the elevator car up and down between floors in the shaft by means of a system of ropes or cables, usually made of steel.

By controlling the rotation of the traction motor, the elevator’s speed and direction are controllable. The traction machine is the electric motor that drives a sheave or pulley system that moves the elevator cables .

The cables are connected to the elevator car and counterweight by the traction machine. Therefore, it is proper to say the elevator car is connected by the traction machine. The traction machine’s rotation is regulated to run the car in the correct direction and at the proper speed.

Among the key advantages of traction elevators and related traction machines is efficiency and dependability. They can easily get passengers or assets to or from floors in edifices with superbly minimum energy ingestion.

Furthermore, the traction machine powers press the exactness of elevator movement in both move and move, ensuring passengers encounter a comfortable and smooth run .

Traction machines have different setup arrangements, depending on the design of the elevator and how much it weighs capacity. The machines are usually installed on the opening or boxes of the elevator tubing to meet the building’s exact needs.


Elevator Traction Machine Types

Different types of elevator traction machines are available, based on several factors including deceleration method, the type of drive motor, and the structure.
The various types help manufacturers, designers, and building owners to choose the right model depending on factors like height of the building or space available, energy efficiency, and performance needed.

The following are the main types:

By Deceleration Method

Elevator Geared Traction Machine

The elevator geared traction machine employs a gearbox to bring down the motor’s rotational speed prior to transmitting it to the sheave or pulley system. This type of traction machine is suitable for the mid-rise building and is pocket-friendly.

Elevator Gearless Traction Machine

The elevator gearless traction machine, on the other hand, does not require a gearbox. Moreover, this machine links the motor directly to the drive systems sheave or pulley. For instance, due to its smaller size, this traction machine is installed in high buildings with a small or limited space. Moreover, most people prefer it due to its efficiency and energy saving.

By Structure

Horizontal Elevator Traction Machine

The horizontal traction machines are usually placed in machines installed horizontally and, which are placed outside the elevator shaft in a storeroom. Buildings with sufficient space to accommodate a separate machine room usually have this type of machine.

Vertical Elevator Traction Machine

The vertical traction machines are usually located in the elevator shaft, only the cage and sheave are put inside the net. The vertical traction machine is mounted in the shaft and does not require a separate machine room. These machines are suitable for buildings where there is limited space or where machine-room- also possible.

By Drive Motor

DC Elevator Traction Motor
DC elevator traction motors are motors powered by direct current. They were traditionally used as elevator motors but are less common today due to the development of better AC motor technologies.

AC Elevator Traction Motor
AC traction motors are modern elevator motors, replacing the outdated DC models. They feature a more energy-efficient design that provides continual and reliable operation. AC motors are made in several different configurations to suit various load capacities and speeds.

Permanent Magnet Synchronous Traction Machine
The permanent magnet synchronous traction machine is the most common type of AC motor used in elevators. Due to the permanent magnets on the rotor, the PMSM engine offers high performance and energy-saving possibilities.
In addition to their durability and reliability, these engines provide accurate command, quiet operation, and rapid acceleration.
The PMSM engine uses a lightweight architecture and may be incorporated into many different elevator designs, including those without a machinery room. This is why it is the best-selling AC traction machine available on the elevator industry market.

How An Elevator Traction Machine Works?

An elevator traction machine is the critical component of traction elevator systems in spatially moving elevator cars up and down a shaft.

The traction machine operates based on the principle of electromechanical traction, utilizing an electric motor to provide force to a sheave or pulley system. The rotational motion generated by the motor is handed down to the sheave or pulley.

The sheave is usually linked to a series of steel ropes or cables, which, in turn, are attached to the elevator car. Based on the intended direction of travel, it winds or unwinds the cables as it turns.

If the motor is reeling in the cables on the sheave, then the elevator car is being raised and vice versa. When the motor is unreeling the cables, the automobile is lowering. It is worth mentioning that the elevator car’s movement is well-regulated through the traction machine’s motor rotation.

The traction machine is rich in safety features such as overspeed governors and braking systems to ensure that the elevator does not move fast or come down ungoverned.


The traction machine underpins the elevator and is accountable for the vertical motion of the car inside the shaft. Selecting an appropriate elevator traction machine manufacturer is essential to guarantee the elevator’s reliability, safety, and performance. So, get in touch with Dazen today!
