Abstract
The invention provides a motor driver. A support plate of the motor driver is fixed on a fixed bottom case of a power element. The power element is fixed on the fixed bottom case of the power element on one side of the support plate. A driver board is fixed on the upper part of the power element. A direct current connecting copper bar is fixed on the lower part of the other side of the support plate. One end of a direct input copper bar is connected with the direct current connecting copper bar, and the other end of the direct current input copper bar is positioned on the upper part of the support plate. An insulator is fixed between the direct current input copper bar and the support plate. One end of an output alternating current copper bar is connected with the power element, and the other end of the output alternating current copper bar is positioned on the upper part of the support plate. An insulator is fixed between the output alternating current copper bar and the support plate. Compared with the prior art, the motor driver reduces electromagnetic interference in printed circuit boards such as the driver boards, control boards and the like because the output alternating current copper bar does not pass above the driver board. The motor driver is convenient to mount and maintain, and the electromagnetic compatibility of the motor driver is improved.
Description
Technical field
The present invention relates to a kind of motor driver, belong to Drive technology field.
Background technology
In electric automobile industry, motor driver is one of critical component of electric automobile.Motor driver is except meeting the feature such as volume is little, structure optimization, and first the electric property of motor driver more should merit attention.The PCB such as existing motor driver internal control plate, drive plate, due to design, its Electro Magnetic Compatibility is poor, and installation and maintenance are comparatively inconvenient.
Summary of the invention
The object of the invention is in order to solve existing motor driver Electro Magnetic Compatibility poor, the problem that installation and maintenance are comparatively inconvenient, and then a kind of motor driver is provided.
The present invention includes the fixedly drain pan of power component, drive plate, power component, output AC copper bar, supporting plate, insulator, direct current input copper bar is connected copper bar with direct current, described supporting plate is fixed on the fixedly drain pan of power component, described power component is fixed on the fixedly drain pan of power component of supporting plate one side, described drive plate is fixed on the top of power component, described direct current connects the bottom that copper bar is fixed on supporting plate opposite side, one end of described direct current input copper bar is connected copper bar with direct current and is connected, the other end of direct current input copper bar is arranged on the top of supporting plate, between direct current input copper bar and supporting plate, be fixed with insulator, one end of described output AC copper bar is connected with power component, the other end of output AC copper bar is arranged on the top of supporting plate, between output AC copper bar and supporting plate, be fixed with insulator.Described output AC copper bar is zigzag.
Beneficial effect of the present invention: compared with prior art, output AC copper bar does not pass through from drive plate top, has reduced like this to drive plate the electromagnetic interference of the PCB such as control board in the present invention.The Electro Magnetic Compatibility that the present invention is convenient for installation and maintenance, improved motor driver.

In Fig. 1 and Fig. 2, Reference numeral 11 is drain pans, the 12nd, and drive plate, the 13rd, control board, the 14th, power component.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail: the present embodiment is implemented take technical solution of the present invention under prerequisite, provided detailed execution mode and specific operation process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 3 and Figure 4, a kind of motor driver, the fixedly drain pan 1 that comprises power component, drive plate 2, power component 3, output AC copper bar 4, supporting plate 5, insulator 6, direct current input copper bar 7 is connected copper bar 8 with direct current, described supporting plate 5 is fixed on the fixedly drain pan 1 of power component, described power component 3 is fixed on the fixedly drain pan 1 of power component of supporting plate 5 one sides, described drive plate 2 is fixed on the top of power component 3, described direct current connects the bottom that copper bar 8 is fixed on supporting plate 5 opposite sides, one end of described direct current input copper bar 7 is connected copper bar 8 and is connected with direct current, the other end of direct current input copper bar 7 is arranged on the top of supporting plate 5, between direct current input copper bar 7 and supporting plate 5, be fixed with insulator 6, one end of described output AC copper bar 4 is connected with power component 3, the other end of output AC copper bar 4 is arranged on the top of supporting plate 5, between output AC copper bar 4 and supporting plate 5, be fixed with insulator 6.
Described output AC copper bar 4 is zigzag.
Described output AC copper bar 4, direct current input copper bar 7 is connected copper bar 8 to be made by copper plate with direct current, have cost low, process the advantages such as simple, be suitable for producing in batches.
DC master row connects DC cable input dc power, three-phase alternating current busbar is by power component output output three-phase alternating current, because the electric current by " Z " font output AC copper bar is larger, output AC copper bar does not pass through from drive plate top, has reduced the electromagnetic interference to drive plate, control board.
