On have certain thrust, so that superconducting magnet be made to have certain acceleration.
Superconductor has zero resistance nature, i.e., when superconductor is passed through DC current, superconductor both end voltage is
Zero, i.e., no power loss, but when superconductor is passed through alternating current or when in the external magnetic field of alternation, due to superconductor
Flux pinning effect, certain power loss, commonly referred to as A.C.power loss can be generated.
The resistive magnet input current of superconducting linear motor is provided by current transformer, the error that is designed due to current transformer itself and
In view of superconducting linear motor practical engineering application, therefore not only there is fundamental wave magnetic field in the magnetic field that resistive magnet generates, also contains phase
When the harmonic field of a part, wherein fundamental wave magnetic field and superconducting magnet interaction generate the thrust needed, but harmonic field is wanted
It is to enter in superconducting magnet, not only will increase the A.C.power loss of superconducting magnet, increases the risk that superconducting magnet quenches, and also and superconduction

Coil can also suitably reduce the heat radiation of system, reduce the leakage heat of magnet system, increase the reliability of superconducting magnet.
However, having the disadvantages that (1) cold screen structure needs are placed in such a way that cold screen carries out electromagnetic protection at present
Inside superconducting magnet, but in ultrahigh speed superconducting magnet, general internal structure is very compact, cold screen not easy to place, and works as superconduction
When the field frequency shielded needed for magnet is lower, the thickness of cold screen is thicker, not only will increase the general assembly difficulty of superconducting magnet in this way,
It also will increase the weight of superconducting magnet；(2) in ultrahigh speed top load environment, the fixation of cold screen and structural strengthening are also very in distress
Degree；(3) since ultrahigh speed superconducting magnet inner space is limited, after superconducting magnet vacuumizes, outer Dewar is likely to lead to contract
Cause is contacted with cold screen, excessive so as to cause leakage heat, is easily caused and is quenched.Therefore cold screen is only placed inside superconducting magnet may
The requirement of shielding high frequency magnetic field is not achieved.In ultrahigh speed environmental applications, the weight and leakage heat of superconducting magnet are very important
Index, if superconducting magnet is overweight or leakage heat is excessive, it is likely that cause superconducting magnet speed that design requirement is not achieved even direct
Cause to quench.

The consumption of incident field energy is caused, the electromagnetic field for as a result making conductor total is substantially exponentially decayed with depth, the depth one
As be known as penetration depth.The calculation formula of penetration depth are as follows:
Wherein, δ is penetration depth, and f is the frequency of incident magnetic, and μ is the magnetic conductivity of shielding material, and σ is shielding material
Conductivity.By formula (1) it is found that frequency is higher, conductivity is bigger, magnetic conductivity is bigger, penetration depth is smaller, when shielding material thickness
When degree is greater than penetration depth, which has good electromagnetic shielding action.The constant situation of other conditions conversely speaking,
Under, if thinking, shielding incident magnetic frequency range is big, then thickness needed for shielding material will be thicker.What Fig. 3 was indicated is different screens
Material thickness relationship needed for covering material under institute's screening frequencies, as shown in Figure 3, under the magnetic field of same frequency, copper shield
Thickness it is thinner than aluminium, this is because the conductivity of copper is higher.On the other hand, when the frequency shielded is lower, needed for screen
The thickness for covering material is thicker.For example, in the application of some ultrahigh speed superconducting magnets, such as ultrahigh speed superconducting linear motor,
The fundamental wave magnetic field of general resistive magnet in 300Hz hereinafter, the magnetic field of 300Hz or more preferably both masks, can be with according to formula (1)
