1) The next spatial harmonic magnetic field (n is a positive integer) is generated, and the spatial harmonic magnetic field is characterized in that the lower harmonics are larger. Therefore, the magnetic pole pitch of the current collecting coil 12 may be set to an integral multiple of τ / 5 corresponding to the spatial harmonic magnetic field so that the speed electromotive force due to the fifth spatial harmonic magnetic field is obtained. Is a three-phase circuit, the coil pitch τ 2 of the current collecting coil 12 needs to be an integral multiple of 2τ / 15. In this example, the magnetic pole pitch of the current collecting coil 12 is 2τ / 5, The pitch τ 2 of the coil 12 is 4τ /
It is set to 15. The magnetic pole pitch of the current collecting coil at this time is
Since it is not an integral multiple of τ / 7, which is the magnetic pole pitch of the spatial harmonic magnetic field other than the fifth order, especially the seventh largest spatial harmonic magnetic field, a velocity electromotive force is generated in the current collecting coil 12 by the seventh spatial harmonic magnetic field.

A next spatial harmonic magnetic field (n is a positive integer) is generated, and the spatial harmonic magnetic field is characterized in that the lower harmonics are larger.
Therefore, the magnetic pole pitch of the current collecting coil 12 may be set to an integral multiple of τ / 2 corresponding to the spatial harmonic magnetic field so that the speed electromotive force due to the second spatial harmonic magnetic field is obtained. Is a three-phase circuit, the coil pitch τ 2 of the current collecting coil 12 needs to be an integral multiple of τ / 3. In this example, the magnetic pole pitch of the current collecting coil 12 is τ / 2
And the pitch τ 2 of the current collecting coil 12 is τ / 3. At this time, the magnetic pole pitch of the current collecting coil 12 is an integral multiple of τ / 4, which is the magnetic pole pitch of the spatial harmonic magnetic field other than the second-order spatial harmonic field, particularly the next largest fourth-order spatial harmonic magnetic field. Then, a speed electromotive force is generated by the fourth-order spatial harmonic magnetic field, and the amplitude and phase balance of the speed electromotive force of the three-phase circuit are lost, so that the collected power decreases.

う問題がある。As shown in this example, if the levitation coil 13 generates a spatial harmonic magnetic field twice as large as the spatial harmonic magnetic field desired to be used in the inductive current collector due to the configuration of the system, and its influence cannot be ignored. There is a problem that the balance between the amplitude and the phase of the speed electromotive force of the three-phase circuit of the current collecting coil 12 is broken, and the current collected is reduced.

を目的とする。According to the present invention, the above-mentioned problems are eliminated, and the current-collecting coil is shifted from the coil connected to the three-phase pole by the magnetic pole pitch of the magnetic field whose position is to be used, with respect to the coil.
In addition, by making the winding direction opposite and combining the coils connected in three-phase poles, the velocity electromotive force due to the harmonic component magnetic field twice as high as the spatial harmonic magnetic field to be used in the inductive current collector is obtained. By eliminating, the three-phase circuit eliminates the imbalance in the amplitude and phase of the speed electromotive force,

1) The next spatial harmonic magnetic field (n is a positive integer) is generated, and the spatial harmonic magnetic field is larger for lower harmonics, and the second and fourth spatial harmonic magnetic fields are larger. Therefore, the current collecting coil 103 is set so that the speed electromotive force due to the second spatial harmonic is obtained.
The magnetic pole pitch of A is given by τ /
2, and the coil pitch τ 2 of the current collecting coil 103A is set to τ / 3 in order to form the current collecting coil 103A into a three-phase circuit. The position of the current collecting coil 103B is shifted from the current collecting coil 103A by τ / 2, which is the magnetic pole pitch of the secondary spatial harmonic magnetic field, and the winding direction is reversed (-in the figure is opposite direction). And a three-phase circuit as shown in the figure. In this case, the position of the current collecting coil 103B is shifted from the current collecting coil 103A by the magnetic pole pitch of the secondary spatial harmonic magnetic field.
The secondary spatial harmonic magnetic field in the opposite direction is linked, and the winding direction is opposite, so that the velocity electromotive force finally has the same phase as that of the current collecting coil 103A. .
