Abstract

The invention relates to a device for controlling the open and close of lifter door, especially a lifter door switch controller with non-gear speed reducer, wherein the controller via the rotor position signal output by the increment coder or other position sensor uses the spatial voltage vector impulse modulation (SVPWM) frequency-variable speed adjustment, to control the magnetic-permanent synchronous motor, to generate stable electromagnetic torque, to flexibly and smoothly adjust the size and direction of motor speed in large range; and said controller uses the position signal to find the position and speed of lifter door, to switch the lifter door, via preset smooth speed curvature. The inventive driver has high efficiency, low cost, and non-gear speed reducer.

Description

technical field [0001] The invention relates to a device for controlling the opening and closing of elevator doors, in particular to an elevator door switch control device with high efficiency, maintenance-free, low cost, low noise and no gear reduction mechanism. Background technique [0002] The elevator door system is composed of door machine system, car door, hall doors of each floor, links and safety protection devices. The door operator system is installed on the car to control the opening and closing of the car door. When the elevator car arrives at a stop on any floor, the door knife and other mechanisms can ensure the linkage between the car door and the hall door of the current floor. The structure schematic diagram of the common elevator door driving device is as follows: figure 1 shown. As shown in the figure, a common elevator door driving device includes: 1. a power supply for providing the required power; a controller 2 in the driving device 4 controls the m...
