Geared machines can reach speeds up to 500 ft./min. These models will have a middle-of-the-road cost in terms of initial investment, maintenance costs and energy consumption. Gearless Elevators. In gearless traction elevators, the sheave is attached directly to the end of the motor. These models can reach speeds up to 2,000 ft./min. These
In addition to gearless elevator machines, ZIEHL-ABEGG also offers various drive systems with gearboxes, which are especially suited for the use of traction sheaves with large diameters. The drive systems are designed for payloads of 400 to 3.000 kg and traveling speeds of up to 2.5 m/s, with a maximum traction sheave diameter of 800 mm.
Higher, faster, smoother. Traction elevators move using a system of steel ropes or belts. This configuration enables them to move faster than hydraulic elevators. They can also travel longer vertical distances, making them ideal for mid-rise, high-rise, and even ultra-high rise buildings. TK Elevator offers a wide variety of traction elevators
The main goal of energy-efficient buildings is to keep energy consumption as low as possible. However, little attention has been paid to energy-efficient elevator systems, which can lead to significant energy savings in buildings [6]. Elevators typically account for 2% to 10% of a building''s energy consumption [7], but, in high-rise buildings
Energy Reports. Volume 9, Supplement 8, Initially, elevators were not technologically mature, with few safety protections, and as a transportation device that people are in close contact with, any single elevator failure could be fatal. The overall model of the elevator traction machine permanent magnet synchronous motor speed
G stands for the weight of the elevator car. Elevator counterweight ≈ elevator car weight + elevator rated load ×0.5. For example, if the elevator car weight is 3,000 lbs, and its maximum load weight is 4,000 lbs, and you choose a ratio of 0.5, the calculation would be: Elevator Counterweight = 3,000 lbs + 4,000 lbs * 0.5 = 5,000 lbs.

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.
Compared with traditional elevator traction machines, permanent magnet elevator traction machines do not require a gearbox device and have higher power and lower energy consumption. In addition, the permanent magnet elevator traction machine also adopts advanced bearingless technology, which can achieve smoother and more
A typical traction machine consists of the following components: Motor: This electric motor provides the rotational force to drive the system. Sheave: A grooved pulley wrapped with the traction cable. Brake: This device ensures safe stopping of the elevator. Inverter/Drive: This controls the motor''s speed and direction.
