Abstract

The utility model relates to a double-output motor structure, belonging to motor technical field. The structure has two output terminals, a control chamber arranged between a motor and a gear box, and a speed measuring magnetic ring and a Hall sensor positioned in the control chamber, wherein the Hall sensor is arranged beside the speed measuring magnetic ring. The motor structure has two output shafts and two identical gear boxes simultaneously arranged on both ends of the motor shaft to obtain completely synchronous outputs at the both ends. The motor with the above structure can be arranged at the middle of a window curtain or a retractable curtain to produce synchronous and stable moments on both ends so as to control the curtain to make stable movement, and the output travel of the motor can be controlled by the speed measuring magnetic ring and the Hall sensor connected with each other. Accordingly, the utility model has good output synchronism and effective setting of output travel, and is suitable for devices with travel range such as curtain.

Description

The dual output electric machine structure

Technical field

The utility model relates to a kind of dual output motor, and especially a kind of curtain that has the stroke self check is used for micro-machine, belongs to the technical field of electric motor structure.

Background technology

Generally adopt linear electric motors and control switch two parts at curtain with motor, adopt the elementary as master slider of linear electric motors as Chinese patent CN94106858.7, secondary conduct is slip pipe fixedly, and master slider is located at fixedly in the slip pipe, and joins with fixing slip pipe work.It utilizes the linear electric motors principle to be applied on the electric controller for curtain, and with elementary be included in secondary in, overcome and to have installed and fixed slip pipe at the two ends of curtain slide bar in the past and cause unsuitable long, the unsuitable overweight defective of cord of slip pipe, and used manual and two kinds of control modes of remote control, make the present invention more be tending towards advanced perfect, be suitable for places such as each big hotel, cinema and use.The disclosed a kind of Linear motor of Chinese patent CN98204323.6 and for example.It is a kind of motor of linear fashion motion.Can be used for spurring the occasion that curtain curtain etc. needs straight reciprocating motion.This Linear motor mainly is made up of two parts.The main body of part motor, it is made up of motor housing and one group of coil.Motor coil gives reserving around one and is used to pass the space coiling that motor slides bar, and another part is that magnetic material of a usefulness is made, and slides bar from the middle motor that passes of electric mover.When passing through electric current in the coil of Linear motor, the magnetic field that coil produced acts on mutually with the magnetic field of sliding bar and makes Linear motor just slide back and forth movement on the bar.But above-mentioned motor is arranged on an end of curtain or other devices usually, make stressed even inadequately, because the stroke of motor will be controlled strictness, above-mentioned motor is not enough in the often precision that addresses this problem, thereby causes the overload of motor to form wearing and tearing easily or burn.

Summary of the invention

The utility model purpose is to provide a kind of dual output and has the motor that detects control, has solved the problems referred to above that prior art exists.

Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs:

A kind of dual output electric machine structure is characterized in that motor has two outputs, is provided with the control room between motor and reduction box, is provided with test the speed magnet ring and Hall element in the control room, and is suddenly described and transducer is arranged on by the magnet ring that tests the speed.Motor shaft is provided with output shaft simultaneously at two ends, two ends are provided with reduction box simultaneously, the reduction box at two ends is identical, synchronous fully by the output of two ends deceleration at last, this motor is arranged on the middle part of curtain or flexible curtain, two ends produce the moment of synchronism stability simultaneously, this makes that the motion of curtain is very steady, by being set in the control room, the magnet ring that tests the speed links to each other with Hall element, Hall element is measured and with the delivery stroke record of motor shaft and measure, when the output of motor shaft reaches set point, pass through the output of external signal control terminal motor, thereby avoided the overload of motor.

As preferably, rotating disk, bearing are housed on the motor shaft of described motor, are embedded with one or uniform embedding polylith permanent magnet around the rotating disk and constitute the magnet ring that tests the speed, be provided with terminal block in the outside of the magnet ring that tests the speed, be provided with Hall element on terminal block, bearing fixing is on connecting plate.Rotating disk is set on the motor shaft, some permanent magnets are set on rotating disk, described permanent magnet is arranged on the outer rim of rotating disk, rotating disk is along with the rotation of motor shaft, and when permanent magnet near Hall element the time, Hall element produces pulse current, pass through rolling counters forward, the output of power machine in when reaching set point so just can have been set the delivery stroke of motor, thereby avoids motor in expansion such as curtain or the overload of shrinking motor when finishing.

As preferably, described reduction box adopts planetary reduction box, and described Hall element adopts the switching regulator Hall element.Adopt the synchronism of planetary reduction box in export at two ends of the present utility model better, the switching regulator Hall element makes Hall element and control device better link, and makes to control the output of motor and stop timely more and effective.

Therefore, it is good to the utlity model has two ends output synchronism, can simply effectively be provided with motor delivery stroke, be fit to the apparatus features that curtain etc. has stroke range.

Description of drawings

Accompanying drawing 1 is a kind of structural representation of the present utility model.

Embodiment

Below by embodiment, and in conjunction with the accompanying drawings 1, the technical solution of the utility model is described in further detail.
