Description
Technical field
The utility model relates to electric motors, especially a kind of brush holder assembly that can bear the rareearth permanent-magnet DC motor of large electric current.
Background technology
The DC motor that has brush, must rely on brush to realize the commutation of motor, and brush must be placed on brush carrier Inner, and brush carrier need fix with the end cap of motor, forms brush handle assembly, and it is the requisite critical components of various brush DC motors.The brush handle assembly of all kinds of brush DC motors, varied, of a great variety.Generally drive the brush handle assembly of class DC motor both at home and abroad, its load current can bear is little of several peaces, greatly to tens peaces, can bear ampere load current up to a hundred and continuously-running and reliable, real genus phoenix feathers and unicorn horns.Existing low-voltage, high-power rareearth permanent-magnet DC motor, little 100A, maximum reaches 240 300A even, and must meet the requirement of operation continuously.Because its load current is large especially, can not find applicable brush handle assembly at all, need to research and develop voluntarily, tackling key problem breaks through.
Utility model content
The technical problems to be solved in the utility model is: for the brush holder assembly of a kind of low-voltage, high-power, the rareearth permanent-magnet DC motor that can bear large electric current is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of brush holder assembly that can bear the rareearth permanent-magnet DC motor of large electric current, comprise insulation brush carrier base plate, on an end face of described brush carrier base plate, be provided with some brush carriers of placing two brushes, described brush carrier is along same even circumferential setting, on brush carrier, be fixed with the electrical brush pressure spring of constant pressure, on another end face of described brush carrier base plate, evenly offer some and can place the groove that connects wire, in groove, be distributed with the enamel covered wire that can bear large electric current, brush carrier base plate sidepiece is provided with some motor binding posts, described motor binding post and enamel covered wire firmly weld.Due to some brush carriers of placing brush being set on the same circumference at an end face of brush carrier base plate, can bear especially big load current.Owing to evenly offering some on brush carrier base plate other end, can place the groove that connects wire, can be placed in groove connecting wire, thereby reduce to connect the space that wire takies, make this brush handle assembly separated time reasonable, structure is compacter.
Described brush carrier, connection wire are fixed on brush carrier base plate by securing member respectively, and fixation, is convenient to installing/dismounting.
The beneficial effects of the utility model are: the utility model can bear that the brush holder modular construction of rareearth permanent-magnet DC motor of large electric current is compact, step line is reasonable, owing to placing two brushes in brush carrier, bottom plate groove is built-in with the long-pending enamel covered wire of enough sections, thereby the especially big load current requirement of operation continuously that can bear 200-240A, its peak current in short-term that can bear can be up to 350-400A, the scope of application is wider, has popularizing value.

In figure: 1. brush carrier base plate, 12. brush carriers, 13. connect wires, 14. securing members, 15. grooves, 2. brush, 3. electrical brush pressure spring, 4. motor binding post.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As Figure 1-4, a kind of brush holder assembly that can bear the rareearth permanent-magnet DC motor of large electric current, comprise insulation brush carrier base plate 1, on an end face of described brush carrier base plate 1, be provided with some brush carriers 12 of placing brush 2, described brush carrier 12 is along same even circumferential setting, on brush carrier 12, be fixed with the electrical brush pressure spring 3 of constant pressure, on another end face of described brush carrier base plate 1, evenly offer some and can place the groove 15 that connects wire 13, in groove 15, be distributed with the enamel covered wire that can bear large electric current, brush carrier base plate 1 sidepiece is provided with some motor binding posts 4, motor binding post 4 firmly welds with enamel covered wire.Due to some brush carriers 12 of placing brush 2 being set on the same circumference at 1 one end faces of brush carrier base plate, can bear especially big load current.Owing to evenly offering some on brush carrier base plate 1 other end, can place the groove 15 that connects wire 13, can be placed in groove 15 connecting wire 13, thereby reduced to connect the space that wire 13 takies, made this brush handle assembly separated time reasonable, structure is compacter.When brush 2 is placed on brush carrier 12, each brush 2 adopts internal pressure between effective life to keep constant electrical brush pressure spring 3 to push down.
Described brush carrier base plate 1 adopts and can make by resistance to 180 degrees Celsius of above high-temperature insulation materials, solid and reliable, long service life.
The interior placement of described groove 15 can be born large electric current, its sectional area is not less than the connection wire 13 of 25 square millimeters.
In order further to improve the load current of this brush handle assembly, on each brush carrier 12, place two brushes 2 that can bear the high current density that is not less than 24 amperes every square millimeter.
Described brush carrier 12, connection wire 13 are fixed on brush carrier base plate 1 by securing member 14 respectively, and described securing member 14 is preferably bolt, and fixation, is convenient to installing/dismounting.
Compared with prior art, the utility model can bear that the brush holder modular construction of rareearth permanent-magnet DC motor of large electric current is compact, step line is reasonable, because brush carrier 12 is interior, can place two brushes 2, bottom plate groove 15 is built-in with the long-pending enamel covered wire of enough sections, thereby the especially big load current requirement of operation continuously that can bear 200-240A, its peak current in short-term that can bear can be up to 350-400A, and the scope of application is wider, has popularizing value.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
