Description

A kind of Novel motor controller

Technical field

It the utility model is related to electric machine controller, more particularly to a kind of Novel motor controller.

Background technology

With the fast development of electric automobile industry, the miniaturization to electric machine controller product, assembling is simple, and cost is low etc. It is required that it is higher and higher, so as to be also required to new structure to meet this requirement.Electric machine controller capacitor core of the prior art Place into plastic casing after being fixed with copper bar by way of spot welding crimping, then fixed toward encapsulated epoxy resin in plastic casing Capacitor core and copper bar, are finally fixed on whole capacitance on electric machine controller by mounting leg.Above outlet method exists The problem of be：

1）Since the thermal conductivity factor of plastic shell is very low, the weak heat-dissipating of whole capacitance.

2）Capacitance need to be screwed in above electric machine controller, assembling trouble.

3）Small product size is bigger, shares product cost costly.

Utility model content

For defect existing in the prior art or deficiency, technical problem to be solved in the utility model is：There is provided one Kind can solve in the prior art the motor for the technical problems such as electric machine controller heat dissipation performance is low, with high costs and volume is bigger Controller.

To achieve these goals, the technical solution that the utility model is taken fills to provide a kind of Novel motor controller Put, including electric machine controller cabinet and capacitance, the capacitance include partition plate, are respectively arranged at the capacitor core of the partition plate both sides And copper bar, the capacitor core are fixed by spot welding and the copper bar, the partition plate, capacitor core and copper bar pass through epoxy resin It is fixed in the electric machine controller cabinet.

As further improvement of the utility model, filled in advance between the electric machine controller cabinet and the capacitor core There is epoxy resin.

As further improvement of the utility model, the electric machine controller cabinet is equipped with card slot, the card slot：For The fixed partition plate.

As further improvement of the utility model, the partition plate is plastic septum.

The beneficial effects of the utility model are：The utility model by capacitor core and copper bar by being put into electric machine controller machine Then case pours into epoxy resin and fixes, the capacitance structure mode being fixed in controller, without assembling, encapsulating straight forming, Eliminate component plastic casing so that the heat dissipation performance of capacitance greatly increases, and reduces the spoilage of capacitance；Further through plastic partition Plate prevents epoxy resin from overflowing；Some epoxy resin of inoculated ensure between capacitor core and cabinet on electric machine controller cabinet again Safety；And it is left in electric machine controller cabinet that capacitor core after some limited posts can effectively prevent embedding has been done on cabinet Move right the back-and-forth motion with capacitor core；The epoxy resin of embedding at the same time is closely linked with electric machine controller cabinet, It can be good at the vibrations requirement for meeting auto parts and components.

Embodiment

Explanation and embodiment further illustrate the utility model below in conjunction with the accompanying drawings.

As shown in Figure 1, electric machine controller capacitor core 01 of the prior art and copper bar 02 are consolidated by way of spot welding crimping Placed into after setting in plastic casing 05, then toward encapsulated epoxy resin fixed capacity fuse 01 and copper bar 02 in plastic casing 05, Finally whole capacitance is fixed on electric machine controller by mounting leg 06.

As Figure 2-3, the utility model provides a kind of Novel motor controller, including electric machine controller cabinet 04 and electricity Hold, the capacitance includes partition plate 03, is respectively arranged at the capacitor core 01 and copper bar of 03 both sides of partition plate, the capacitor core 01 is fixed by spot welding and the copper bar 02, and the partition plate 03, capacitor core 01 and copper bar 02 are fixed on institute by epoxy resin State in electric machine controller cabinet 04.

Further, it is prefilled with epoxy resin between the electric machine controller cabinet 04 and the capacitor core 01.Institute State electric machine controller cabinet 04 and be equipped with card slot, the card slot：For accommodating the partition plate 03 specifically, the partition plate 03 is modeling Expect partition plate.

In the prior art, it is necessary to which plastic casing 05 is initially used for carrying the capacitor core 01 and copper bar 02, because plastics Heat conductivility it is bad, cause the heat dissipation performance of capacitance poor, the capacitive faults because caused by overheating capacitance, and plastics easily occur Housing 04 make it that the volume of whole capacitance is larger, is unsatisfactory for the small form factor requirements of electric machine controller；And mounting leg 06 is needed again Capacitance is fixed on electric machine controller with screw, mounting means is cumbersome, and mounting leg 06 adds the body of electric machine controller again Product so that the cost increase of production.

The beneficial effects of the utility model are：The utility model eliminates plastic casing 05 and mounting leg 06, Ke Yizhi Connect and the capacitor core 01, copper bar 2 and partition plate 03 are placed directly within the electric machine controller cabinet 04, then pass through asphalt mixtures modified by epoxy resin Fat fixes encapsulation, it is not necessary to device is separately set outside electric machine controller so that the volume of electric machine controller further reduces；And because Mounting leg 06 and fixed screw are eliminated again so that assembly method is compiled simple to operation；The effect of wherein plastic septum is Prevent that epoxy resin overflows during encapsulated epoxy resin.

Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded To belong to the scope of protection of the utility model.
