high quality VVVF passenger elevator

Passenger elevator incorporates state-of-the-art permanent magnet synchronous technology that

contributes to a compact structure of traction machine; additionally, VVVF serial control technology

provides elevators with an ergonomic operating curve as well as smooth and low-noise operation.

The control system is incorporates highly reliable microcomputer serial communication technology for rapid signal response and excellent immunity.When compared with traditional elevators with machine room, small machine room elevator employs more rational civil layout that contributes to less space occupation and lower construction cost.

Elevators are furnished with international leading permanent magnet sychronous gearless traction

machine that features low noise, less conspicious vibration, high system, efficiency and low energy consumption, thereby avoiding environmental pollution that may arise from the use of gear oil in traditional traction machine.

The introduction of cutting-edge VVVF control technology ,precision reducer and all- digital pulse 

width modulation control device and the load-dependent automatic adjustment of elevator startup 

torque guarantee the more smooth acceleration and deceleration of elevator.
