Abstract
An electromagnetic field shielding system of an electric automobile driving motor is disclosed. After a motor (10) is electrified, an induction coil induces a strong electromagnetic field. Simultaneously, the electromagnetic field begins to attack a first layer of shield (5). A first power supply surge protector (19) which is connected with the first layer of shield (5) begins to unload a current. Because pipelines form multiple 90 degrees, the electromagnetic fields at exits of the pipelines can not break through and pass through each pipeline. A second power supply surge protector (29) and a fourth power supply surge protector (35) which are connected with in and out power supply lines reach an unloading effect and an effect of blocking the electromagnetic field to induce the current on the power supply lines. The leakage electromagnetic field passes through the first layer of shield (5). The current is induced on a second layer of shield (1) and a third power supply surge protector (33) unloads the current so that external electromagnetic field intensity of the electric automobile driving motor is reduced. A medical requirement that the magnetic field intensity of the electric automobile driving motor in a range of 0.6 meters is less than 0.4 miu T is reached.

Four, the kind of electromagnetic shielding
4.1 frequency electromagnetic waves shieldings, main employing absorbs and principle of reflection, and frequency electromagnetic waves, when running into metallic shield body, produces strong eddy current effect and electromagnetic wave is absorbed, and simultaneously because its wave impedance is very high, frequency electromagnetic waves produces reflection loss.
4.2 shielding in of magnetostatic fields, during the high magnetic conduction shield of magnetic field by a closure, because the permeability of shield is very high, magnetic resistance is very low, and magnetic field can be derived by magnetic screen path, and significantly reduce in the magnetic field of the shield that makes to bleed.
4.3 ultralow frequency electromagnetic shieldings, mainly take magnetic shielding principle as main, will consider electromagnetic compatibility simultaneously, have the shielding action that part eddy current effect produces.
Five, the principle of electromagnetic shielding and shield manufactured materials chooses
5.1 low frequency electromagnetic Bob frequency electromagnetic waves have higher magnetic-field component, and for low-down interfering frequency, the permeability of shielding material is even more important during more than high frequency.The basic principle of shielding low frequency (as power frequency) electromagnetic interference is magnetic path parallel connection by-pass shunt.Magnetic flux density by using permeability magnetic material (as mild steel, silicon steel etc.) to provide magnetic bypass to reduce shield inside increases eddy current loss simultaneously as far as possible, makes part energy be converted into thermal energy consumption and falls.The thicker magnetic resistance of shielding material is less, eddy current loss is larger, and shield effectiveness is better.Conductance is high and material (as copper, aluminium etc.) that permeability is low does not almost have shielding action to electromagnetic magnetic-field component.
5.2 magnetic permeabilitys are also relevant with externally-applied magnetic field intensity.When externally-applied magnetic field intensity is lower, magnetic permeability raises with the increase of externally-applied magnetic field, and when externally-applied magnetic field intensity surpasses certain value, magnetic permeability sharply declines, and at this time material has occurred saturatedly, once that material occurs is saturated, has just lost magnetic screening action.The magnetic permeability of material is higher, more saturated.Therefore,, in very strong magnetic field, the material that magnetic permeability is very high does not have good screening effectiveness.The magnetic permeability of mild steel is in 4000 left and right, and saturation intensity is in 22000 left and right, low carbon steel plate good mechanical property, good, the easy processing of solderability, is difficult for saturatedly, is the first-selection of low frequency electromagnetic shielding material.

6.2 in three (shielding, ground connection, filtering) major measure of tempest, and often simple employing shields, but complete Spark gap can not be provided, because the cable in equipment or system is the most effective electromagnetic pulse, receive and transmitting antenna.Especially concerning having the equipment of external antenna and system that multiple devices are connected to form by cable, simple shielding cannot reach corresponding requirement of shelter.Effective measures add a filter exactly, cut off electromagnetic pulse along the path of holding wire or power line propagation, with the perfect Spark gap of the common formation of shielding.Filtering is in order to prevent that undesirable electromagnetic viscosimeter from propagating into equipment along any aerial lug being connected with equipment, generally completed by filter.Adopting filter to suppress is one of necessary means of Spark gap, particularly to suppressing, through wire, is coupled to the energy in circuit, and it is a kind of extensive adopted method.
6.3 existing single or multiple lift electromagnetic screens are between outer shield surface, multilayer screen inside and outside layer, in internal layer shield; power source surge protector (SPD) and holding wire, control circuit protector (SPD) are not installed, power source surge protector (SPD) is not installed in earth lead.Highfield and high-intensity magnetic field that electromagnetic pulse produces; can be on power line cable, signal line cable and earth lead; induce several kilovolts of voltages to several ten thousand volts and a few kiloampere to the electric current of several Wan An training; electric current enters in shield along power line cable, signal line cable and earth lead, protected computer in the shielding of destroy or disable internal layer.
