The beneficial effects of the utility model are: between the first insulating surfaces is arranged at the bottom of brush and the end cap, will separate at the bottom of brush and the end cap, avoid at the bottom of brush and the end cap between discharge breakdown; The second insulating surfaces is arranged between brush and the end cap sidewall, and brush and end cap sidewall are separated, and avoids discharge breakdown between brush and the end cap sidewall.
Description of drawings
Fig. 1 is the utility model motor brush fixed structure chart;
Fig. 2 is prior art electric machine structure figure;
Be labeled as among the figure: at the bottom of insulating support 1, electric motor end cap 2, brush card 3, brush slot 4, the second metallic channel 5, the first metallic channel 6, wire 7, brush 8, the first insulating surfaces 9, the second insulating surfaces 10, the end cap 11, end cap sidewall 12.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
In order to provide a kind of insulation effect good motor brush fixed structure, as shown in Figure 1, the motor brush fixed structure comprises electric motor end cap 2 and brush 8, electric motor end cap 2 comprises at the bottom of end cap sidewall 12 and the end cap 11, brush 8 is arranged in the electric motor end cap 2 and with electric motor end cap 2 and insulate, the motor brush fixed structure also comprises insulating support 1, insulating support 1 is fixed on the electric motor end cap 2, brush 8 is fixed on the insulating support 1, insulating support 1 comprises the first insulating surfaces 9 and the second insulating surfaces 10, the first insulating surfaces 9 is arranged at the bottom of brush 8 and the end cap between 11, and the second insulating surfaces 10 is arranged between brush 8 and the end cap sidewall 12.The first insulating surfaces 9 is arranged at the bottom of brush 8 and the end cap between 11, with brush 8 with 11 separate at the bottom of the end cap, avoid at the bottom of brush 8 and the end cap discharge breakdown between 11; The second insulating surfaces 10 is arranged between brush 8 and the end cap sidewall 12, and brush 8 and end cap sidewall 12 are separated, and avoids discharge breakdown between brush 8 and the end cap sidewall 12.Insulating support 1 and electric motor end cap 2 connected modes can be insulating supports 1 and 11 be threaded at the bottom of the end cap, also can be that insulating support 1 is threaded with end cap sidewall 12.
Brush 8 is fixed in mode on the insulating support 1 can be had multiplely, and this uses novel optimal way to be: the brush fixed structure comprises brush card 3, brush card 3 interior formation brush slots 4, and brush 8 is arranged in the brush slot 4, and brush card 3 is connected with insulating support 1.Brush slot 4 shapes and brush 8 shapes are adaptive, and brush 8 can only be endwisely slipped along brush slot 4; Brush slot 4 is along the radially setting of electric motor end cap 2; Between brush 8 and the second insulating surfaces 10, spring is set, gives brush 8 certain thrust to electric motor end cap 2 centers.
For the ease of fixing cord 7, make cabling regular, be provided with the first metallic channel 6 on the insulating support 1.The first metallic channel 6 can be made one with insulating support 1, and the first metallic channel 6 particular locations arrange according to the cabling needs.
In order further to be convenient to make cabling regular for the ease of fixing cord 7, be provided with the second metallic channel 5 on the brush card 3.The second metallic channel 5 is at wire 7 and fixing cord 7 before brush 8 is connected.
