                Traction machine

                Suzhou Diao Elevator Co.,Ltd | Updated: Jun 29, 2016

                Elevator traction power equipment is an elevator, also known as elevator hosts. Function is to transport and deliver power to make elevator operation. It consists of the motor, brakes, couplings, gearboxes, traction wheels, a frame and guide pulley and attached motor handle and so on. Guide wheel mounted on the frame or on a rack under the load-bearing beams. Manual wheel fixed to the motor shaft, there are usually hung on the wall near, when used on the motor shaft.

                I. classification by speed

                1. geared machine: driving device of power, passes through intermediate reducer onto the sheave of the tractor, worm drive gear box is usually used (also useful for helical gear), this exchange of traction motors, DC, commonly used for low-speed elevator. Traction is usually 35:2. If the traction motor on the power through the gearbox to the sheave, called a geared machine, commonly used for 2. 5M/s the following low-speed lift.

                2. MRL: actuator dynamics, without intermediate reducer but pass directly onto the sheave of the tractor. Previously most of this tractor is a DC motor as a driving force, has been developed in China now have independent intellectual property rights of AC permanent magnet synchronous gearless traction machine. Traction is usually 2:1 and 1:1. 320kg~2000kg truck, ladder speed 0.3M/s~4.00m/s. Motor powered direct drive without gearbox onto the sheave is called MRL, 2. More than 5M/s high speed elevators and ultra high speed elevator.
