Description
Technical field
This utility model relates to electromagnetic shielding film, particularly to a kind of electromagnetic shielding film for motor and controller and the new-energy automobile comprising it.
Background technology
In short supply in fossil energy and advocate on the premise of green energy resource, new-energy automobile, the development trend such as electric automobile increases the most increasingly, it is well known that the dynamical system of electric automobile is the core of automobile, is the automobile key of saving the energy.Nucleus equipment in power system of electric automobile is the overall performance that the performance of electric motor and controller system, motor and controller directly affects new-energy automobile.
But, dynamical system electromagnetic interference can badly influence the performance of new-energy automobile, new-energy automobile electricity system is caused and has a strong impact on, so on the one hand strengthening the emc testing of new energy motor motor and controller will assist in the quality ensureing new-energy automobile, promote the performance of new-energy automobile；But then, also to take measures to reduce the electromagnetic interference impact on automotive performance.
In prior art, for the source of two main aspect of electromagnetic interference of new-energy automobile motor and control system thereof: one is derived from the circuit of automobile itself, electromagnetic interference in this respect is prevented by measures such as filtering and overall design；Two electromagnetic interference being derived from the external world, and to coming from the electromagnetic interference in the external world, the electromagnetic wave (including broadcast, TV and various automatic controlling devices etc.) as being widely present in space does not but have been resolved.
Utility model content
The technical problems to be solved in the utility model is to overcome the prior art the most insurmountable defect of electromagnetic interference to coming from the external world, it is provided that a kind of electromagnetic shielding film for motor and controller and comprise its new-energy automobile.
This utility model is to solve above-mentioned technical problem by following technical proposals:
A kind of electromagnetic shielding film for motor and controller, its feature is, described electromagnetic shielding film includes:
Outer electro-magnetic screen layer, described outer electro-magnetic screen layer is bonded permanent ferrite；
Interior electro-magnetic screen layer, described interior electro-magnetic screen layer is ferrite；
The thickness of described outer electro-magnetic screen layer is 1～3mm, and the thickness of described interior electro-magnetic screen layer is 1～3mm；
The thickness of described outer electro-magnetic screen layer and described interior electro-magnetic screen layer is than for 1:1；
Offering some apertures on described electromagnetic shielding film, hole diameter is 1～20mm.
A kind of new-energy automobile, its feature is, it comprises the described electromagnetic shielding film for motor and controller.
Preferably, described electromagnetic shielding film is arranged at the Vehicle Electronic Control case of described new-energy automobile.
In this utility model, above-mentioned optimum condition on the basis of meeting common sense in the field can combination in any, obtain each preferred embodiment of this utility model.
Positive progressive effect of the present utility model is:
New-energy automobile motor and controller electromagnetic shielding film of the present utility model, uses double-decker, is possible not only to the electromagnetic interference of shielding automotive circuit itself, it is also possible to the electromagnetic interference that effectively shielding is extraneous.
