The traction machine is composed of an electric motor, a brake, a coupling, a reduction gear box, a traction sheave, a frame and a guide wheel, and an auxiliary wheel hand wheel.
If the motor power of the traction machine is transmitted to the traction sheave through the reduction gearbox, it is called a geared traction machine, and the traction ratio is usually 35:2. It is generally used for low and medium speed elevators below 2.5m/s.
If the power of the motor is not directly transmitted to the traction sheave through the reduction gearbox, it is called a gearless traction machine, and the traction ratio is usually 2:1 and 1:1. The load is 320kg to 2000kg, and the ladder speed is 0.3m/s to 4.00m/s. It is generally used for high-speed elevators and ultra-high-speed elevators above 2.5m/s.
