Abstract
The invention relates to an electric machine, in particular relates to a automatic alarm carbon brush holder capable of self-indicating carbon brush over-short and prompting to replace, which is composed of a brush carrier, a spring and a carbon brush within the brush carrier, and a conductor and a connection terminal, and is characterized in that the brush carrier is provided with carbon brush translational control switch which is connected to a power supply by the conductor, And the conductor is connected with a current limiting resistor, a rectifier diode and a LED. When the carbon brush is abraded to an operating limit, the carbon brush translational control switch will close, so that a V-shaped end of an elastic slice fall into a slot of the brush carrier completely, and a mobile electric shock block of the elastic slice and a still electric shock block on the brush carrier contact with each other to switch on the power supply, here the LED gives an alarm by lighting and prompts user to replace the carbon brush, and the electric machine rotor is protected from being damaged. The electric machine has simple structure, stabilizing operation and low cost and the like.
Description
Technical field:
Invention 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 invention 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.
Invention 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.
Inventing described carbon brush mobile switching control 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 invention 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.
