Using energy-saving environmental protection, stable running, low noise, small area of permanent magnet synchronous traction machine:
1, simple structure, without gearboxes, process easier and reduces the volume and weight, improve the effective utilization of space.
2, small vibration, low noise, particularly in the low speed region, more obvious advantages, stability, speed and high accuracy. Most of the traditional gear traction elevator noise from gear box produced by mechanical vibrations and vibration and noise of high speed rotation of the motor itself. Gearless traction machine without gearbox, motor rated speed is very low, thus the vibration and noise of the motor itself is very small, thus noise throughout the lift system is greatly reduced.
