Elevator traction machines can be divided into geared elevator traction machines and gearless elevator traction machines according to the different speed change systems.
Geared elevator traction machine
The geared elevator traction machine is the power of the driving device and is transmitted to the elevator traction machine on the traction sheave through the intermediate reducer. The motors used in the lead-in machine are either AC or DC and are generally used in 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 geared traction machine, which is generally used for low and medium-speed elevators below 2.5m/s.
Gearless elevator traction machine
The gearless elevator traction machine is the power of the driving device, and it does not need an intermediate reducer but is directly transmitted to the traction machine on the traction sheave. In the past, most of these traction machines were powered by DC motors. XIZI FORVORDA has developed permanent magnet synchronous gearless traction machines with independent intellectual property rights. Traction ratios are usually 2:1 and 1:1. The load is 320kg～2000kg, and the ladder speed is 0.3m/s～4.00m/s. If the power of the motor is directly transmitted to the traction sheave without passing through the reduction box, it is called a gearless traction machine, which is generally used for high-speed elevators and ultra-high-speed elevators above 2.5m/s.
