In order to further satisfy the construction’s requirements, “LGEER Elevator Co.,Ltd.” elevator adopts the advanced permanent magnet synchronous motor drive none gear traction machine to save the speed reduction device with large bulk. It greatly reduces the space and improves the layout mode of inside the elevator well. Therefore it needs no machine room any more. The weight to allocate the machine equipments in the well can be transmitted by the steelwork components such as guide-rail etc. in the lower pit of the well. It is not allowed to add the extra structual intensity of the construction, nor does it need a machine room. In this way, it saves the construction space and greatly lowers down the construction cost.
The low noise and low vibration characteristics of permanent magnet synchronous non-gear traction machine combines with the continuously improved micro-computer network control variable frequency speed control mode. It brings about the smooth elevator running and the more quiet and comfortable riding experience.
It combines with the high efficiency drive to enhance the effectiveness and reduces the energy loss. It also avoids the pollution problem which will be caused by the possible permeation from the traditional traction machine gear lubricant. It appears to be more economical to the elevator running at the same time of beautifying the environments.
