The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the schematic diagram of the electric capacity syndeton of the vehicle-mounted Double Motor Control device of the utility model;
Fig. 2 is the another kind of schematic diagram of this syndeton.
Embodiment
As shown in Figure 1, the electric capacity syndeton of the vehicle-mounted Double Motor Control device of the utility model comprises controller box 7, electric capacity 4 and two IGBT modules 1,6, be provided with cooling water channel 8 in the described controller box 7, described two IGBT modules 1,6 are located at respectively on the cooling water channel 8 in the described controller box 7, described electric capacity 4 is located in the described controller box 7 and respectively and is connected described two IGBT modules 1,6 by copper bar installation foot 3,5, and described copper bar installation foot 3,5 adopts bolt 2 fastening.
Further, at the controller box of flush system, above-mentioned electric capacity 4 is between described two IGBT modules 1,6.
Further, as shown in Figure 2, at the controller box of up-down structure, above-mentioned two IGBT modules 1,6 are located at described cooling water channel 8 both sides respectively, and described electric capacity 4 is positioned at described two IGBT modules, 1,6 one sides.
This syndeton adopts an electric capacity to connect the control of two IGBT modules realizations to bi-motor respectively, it has overcome the defective of an IGBT module of an electric capacity connection of tradition, effectively reduced the volume of controller box, reduce the cost of manufacture of electric machine controller, made things convenient for the layout of electric machine controller in automobile; Electric capacity directly connects IGBT module by the copper bar installation foot simultaneously, need not to be connected by the switching copper bar, has simplified the installation of electric machine controller.
