Description
Technical field
The present invention relates to motor controller structure, more particularly to a kind of Novel motor controller capacitor installation structure.
Background technology
Current motor controller structure is that motor controller casing, bus bar copper row, junction block, electric capacity etc. are relatively independent
Individual configurations, geometric superposition, screw fix by way of install, not only between space-consuming but also electric capacity and metal substrate
Thermal resistance is larger, so electric capacity temperature rise, influence capacitance, influence controller complete machine power density.
Electric capacity is arranged on controller substrate, and thermal contact resistance is larger, influence electric capacity radiating, the capacitor's capacity under same volume
Reduction, and then have influence on controller complete machine power density；Bus bar copper row and electric capacity copper bar is inputted by screw to link together,
Bus bar copper row lap-joint contact resistance is big, causes whole bus bar copper row temperature rise higher, and need extra part to bus just
Copper bar does insulation processing, distance between wasting space, and increase both positive and negative polarity bus between negative pole, and then increases whole system electricity
Sense, reduces the stability of system.
The content of the invention
The present invention seeks to：It is that, to avoid the technical problem present in above-mentioned prior art, the present invention provides a kind of new
Electric machine controller capacitor installation structure, by being molded capacitance core, bus bar copper row, being molded on controller housing, and direct current
Bus terminal block synchronization injection molding, so solve electric capacity problem of temperature rise, save bus between extra insulating part, reduce it is female
Distance between line copper bar, reduces whole system inductance, and installing space is saved again, cost is reduced.
The technical scheme is that：
A kind of Novel motor controller capacitor installation structure, including motor controller casing, capacitance core and bus bar copper row；The electricity
The cavity needed for receiving capacitance core and bus bar copper row is precast with machine controller housing, the capacitance core and bus bar copper row are positioned over
In the precasting cavity of motor controller casing, the remaining space mould filling thing in precasting cavity, capacitance core and bus bar copper row
It is fixed.
It is preferred that, radiation water channel is carried in the controller shell body, for the cooling electronic component being disposed thereon.
It is preferred that, the filler of the remaining space injection in the precasting cavity is epoxy resin.
It is preferred that, the bus bar copper row includes the external connection part of bus that copper bar body and its top edge extend, institute
The top edge for stating the precasting cavity of motor controller casing is precast with the groove being adapted to the external connection part of bus.
It is preferred that, the motor controller casing is Al-alloy casing.
It is an advantage of the invention that：
1. the electric machine controller of the present invention, replaces thin-film capacitor plastic casing itself, i.e., inside electric capacity using Al-alloy casing
Capacitance core, bus bar copper row, bus terminal block etc. are fixed on controller casing by epoxy resin encapsulated；Effectively reduce electric capacity temperature
Rise, lift capacitor's capacity, improve the power density of whole controller；
2nd, by the structure of the present invention, insulating part between bus terminal block, bus is saved, system cost is reduced；
3rd, by distance between the structure reduction bus both positive and negative polarity of the present invention, system capacitance is reduced, the stability of a system is improved；
4th, by the structure of the present invention, fixed, raising system reliability is installed without screw and controller volume is reduced.
Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment the invention will be further described：
Fig. 1 is the structural representation of motor controller casing of the present invention；
Fig. 2 is the structural representation of capacitance core of the present invention；

Embodiment
As Figure 1-4, disclosed Novel motor controller capacitor installation structure, including electric machine controller shell
Body 1, capacitance core 2 and bus bar copper row 3.Controller housing 1 carries radiation water channel, to be placed in cooling electronic component thereon,
The pre- cavity size cast out required for capacitance core 2 and bus bar copper row 3 on controller housing 1, by technology and pattern assembly electric capacity
Core 2, bus bar copper row 3 are fixed in the precasting cavity of controller housing 1, and epoxy resin is molded into controller housing by injection machine
In 1 cavity, capacitance core 2, bus bar copper row 3 are fixed.Because epoxy resin is filled in capacitance core 2, bus bar copper row 3, controller shell
Gap between body 1, that is, protect and solve the electric clearance of conductive component and climb electric problem, the reliability of electric capacity in itself is improved again.
It is fixed on because bus bar copper row 3 is overall by epoxy resin on controller housing 1, solid and reliable, outside input high-voltage wiring harness
It is directly connected on bus bar copper row, bus input wires holder structure necessary to saving controller.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Present disclosure can be understood and implemented according to this, it is not intended to limit the scope of the present invention.It is all main according to the present invention
The modification for wanting the Spirit Essence of technical scheme to be done, should all be included within the scope of the present invention.
