Geared Traction Machine-AF-200A

Short Description:

The power of the traction device is transmitted to the traction machine on the traction sheave through the intermediate reducer, and the reduction box is usually driven by a worm gear (also a helical gear drive). There are also DC ones, which are generally used on low-speed elevators. The draw ratio is typically 35:2. If the motor power of the traction machine is transmitted to the traction sheave through the reduction box, it is called a gearless traction machine, which is generally used for low and medium speed elevators below 2.5m/s.
