Abstract

The utility model provides an elevator door motor, which comprises a door motor bottom plate, a driving device, a driven wheel and a controller, wherein the driving device, the driven wheel and the controller are all installed on the door motor bottom plate, and the driving device is an outer rotor permanent-magnet synchronous motor with a synchronous wheel. Besides, the outer rotor permanent-magnet synchronous motor is vertically installed on the door motor bottom plate; the synchronous wheel is connected with the driven wheel through a synchronous belt; the outer rotor permanent-magnet synchronous motor adopting low rotating speed and large torque is capable of substantially reducing noise, saving energy and protecting environment; the synchronous wheel needing no use of a speed reducer can not only lower noise, but also avoid the problem that the door motor is unstable in running because of mechanical breakdown of the speed reducer; and the outer rotor permanent-magnet synchronous motor vertically installed on the door motor bottom plate has compact and matching overall structure. The special controller of the elevator door motor enables the elevator door motor to be reliable and stable in running, thereby more greatly improving working efficiency, energy-saving property, safety and the like.

Description

Elevator door-motor

Technical field:

The utility model relates to a kind of elevator door-motor.

Background technology:

The actuating device that existing elevator door-motor adopts mostly is threephase asynchronous machine and drives or the DC driven by servomotor, this type of drive all need be used the comparatively complicated transmission system of structure, reduced the driving efficiency of actuating device, this has just increased energy consumption, and the installation of transmission system is also inconvenient, noise during work is bigger, and mechanical breakdown easily takes place, thereby has reduced the service life of elevator door-motor.

The utility model content:

For solving above-mentioned technical matters, the utility model provide a kind of easy for installation, noise is little, the elevator door-motor of energy-conserving and environment-protective.

The technical solution of the utility model is, a kind of elevator door-motor with following structure is provided, comprise a machine bottom board, actuating device, flower wheel and controller, described actuating device, flower wheel and controller all are installed on the machine bottom board, described actuating device is the outer rotor permanent magnet motor that has synchronizing wheel, described outer rotor permanent magnet motor vertically is installed on the machine bottom board, described synchronizing wheel is with through synchronously and is connected with flower wheel, cooperate the utility model elevator door-motor nonshared control unit, make elevator door-motor reliable, stable, thereby at work efficiency, each side such as energy saving and safety get a greater increase.

After adopting said structure, the utlity model has following advantage:

Use the outer rotor permanent magnet motor of slow speed of revolution, high pulling torque can significantly reduce power consumption, energy-conserving and environment-protective, synchronizing wheel is with through synchronously and is connected with flower wheel, do not need to use speed reduction gearing, so not only can reduce noise, also avoided causing problems such as a machine operation shakiness because of the mechanical breakdown of speed reduction gearing, outer rotor permanent magnet motor vertically is installed on the machine bottom board, compact overall structure.

The specific embodiment:

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

As 1 figure, Fig. 2, Fig. 3, shown in Figure 4, same as the prior art, the utility model elevator door-motor comprises a machine bottom board 1, actuating device, flower wheel 14, guide rail 2, left side link plate 3, right link plate 4, left-hand door plate 5, right door-plate 6, door cutter 7, guide wheel assemblies 8 and controller 9, described actuating device, flower wheel 14 and controller 9 all are installed on the machine bottom board 1, described controller 9 is the NICE900 door machine integrated controller, between described actuating device and the flower wheel 14 by being with 10 to be connected synchronously, described left-hand door plate 5 is connected with left link plate 3, right door-plate 6 is connected with right link plate 4, described left link plate 3 and right link plate 4 place on the guide rail 2 by roller 11, described door cutter 7 is synchronous door knife or asynchronous door cutter, it is installed on left link plate 3 or the left-hand door plate 5, the swing arm of described door cutter 7 be with 10 to captive joint synchronously, be provided with guiding steel wire 12 between the described guide wheel assemblies 8, described left link plate 3 is connected with the epimere of guiding steel wire 12, and right link plate 4 is connected with the hypomere of guiding steel wire 12.

Be with the difference of prior art, described actuating device is the outer rotor permanent magnet motor 13 that has synchronizing wheel 13.1, described outer rotor permanent magnet motor 13 vertically is installed on the machine bottom board 1, be that outer rotor permanent magnet motor 13 is vertical with horizontal surface, described synchronizing wheel 13.1 is by being with 10 to be connected with flower wheel 14 synchronously, and the tightening device that is used to regulate synchronously with 10 tensioning degrees is installed in flower wheel 14.

During work, receive instruction by controller 9, following outer rotor permanent magnet motor 13 forward or reverse by synchronizing wheel 13.1 drives and to be with 10 and flower wheel 14 crank motions synchronously, door cutter 7 is with being with 10 horizontal reciprocating movements synchronously, left side link plate 3 and left-hand door plate 5 are followed a cutter 7 along guide rail 2 crank motions, because left link plate 3 is connected with the epimere of guiding steel wire 12, right link plate 4 is connected with the hypomere of guiding steel wire 12, so the motion of left link plate 3 will drive right link plate 4 and right door-plate 6 is synchronized with the movement round about along guide rail 2, thus the function of realization system for elevator door.
