An elevator traction machine is the main drive unit of a traction elevator. It consists of an electric motor, traction sheave (pulley), brake system, and related components that work together to move the elevator car and counterweight.
The machine rotates the traction sheave, which grips the steel wire ropes and raises or lowers the elevator car safely and smoothly. It also controls the elevator's speed and holds the car securely in place when stopped.
