Passenger Conveyor-12 With the VVVF frequency conversion technology, peration curve of the door operator could be adjusted at will. The door system is important for improving overall performance of elevator and comfort of passengers. The AC permanent magnet synchronous door system does not have a reduction device and enjoys flat structure, adopts a design of double closed-loop vector control in speed and current, which is characterized by large output torque at low speed, stable operation, low noise, efficiency and energy saving. Because of flat structure and no reduction device, appearance of the complete machine is compact and structure is simple.
