Abstract
The utility model relates to a motor, in particular to an auto alarm carbon brush shelf which can automatically indicate that the carbon brush is too short and remind people to replace, which consists of a brush holder, a spring and a carbon brush that are in the brush holder, a conductor and a wiring terminal. The utility model is characterized in that the brush holder is provided with a control switch for carbon brush movement and the control switch is connected with the conductor and the power; the conductor is respectively connected with a current-limiting resistance, a rectifier diode and a light emitting diode. When the carbon brush is worn to the working limit, the control switch for carbon brush movement is switched on, which means the V-shaped end of an elastic tablet totally falls into a slotted hole of the brush holder, and a movable electric shock block on the elastic tablet and a static electric shock block on the brush holder are mutually contacted to be connected with a power supply, at the time, the light emitting diode lights to give an alarm to remind users to replace the carbon brush, thus preventing a motor rotor from being damaged. The utility model has the advantages of simple structure, stable working and low cost, etc.
Description
Technical field:
The utility model relates to motor, the specifically a kind of automatic alarming carbon brush holder that can indicate the too short and prompting changing of carbon brush automatically.
Background technology:
As everyone knows, the carbon brush holder that motor is used is by brush holder, spring and carbon brush in the brush holder, lead and binding post are formed, during use, carbon brush holder is fixed on rotor changes the nuchinal organ both sides, carbon brush contacts with commutator under the effect of spring all the time, so that power supply makes its rotation to rotor, but, along with the rotation of motor, the ablation of the electric spark that friction between carbon brush and commutator and friction produce, carbon brush can shorten gradually, when shortening to when certain interval being arranged with commutator, the spark of ablating is very big, will soon burn out commutator, thereby whole rotor is scrapped.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and can indicate the too short and prompting replacing in time of carbon brush automatically, effectively protects the automatic alarming carbon brush holder of rotor.
The utility model can reach by following measure:
A kind of automatic alarming carbon brush holder, be made up of the spring in brush holder, the brush holder and carbon brush, lead and binding post, it is characterized in that brush holder is provided with the carbon brush mobile switching control, control switch is connected with power supply by lead, be connected with current-limiting resistance, rectifier diode and light-emitting diode on the lead respectively.
Carbon brush mobile switching control described in the utility model is to be provided with support in the brush holder rearward end, the brush holder leading section is provided with slotted eye, flexure strip one end is connected with support, the other end is V-shaped and fall in the slotted eye on the brush holder, flexure strip is provided with movable contact electricity piece, and flexure strip and movable contact electricity interblock are provided with insulation cushion, is provided with the static electric shock piece with movable contact electricity piece opposite position on the brush holder, movable contact electricity piece is connected with power supply through lead with the static electric shock piece
When the utility model may wear to operating limit at carbon brush, the carbon brush mobile switching control is connected, be that the V-arrangement end of flexure strip falls in the slotted eye on the brush holder fully, movable contact on the flexure strip electricity piece energized that contacts with static electric shock piece on the brush holder, at this moment, light-emitting diode carries out luminous warning, in time points out the user to change carbon brush, in order to avoid the damage rotor, advantage such as have at the bottom of simple in structure, working stability, the cost.
