On a plane that crosses the A canceling coil having an annular or arc shape is provided surrounding the magnetic flux and adjacent to the generating coil, and the canceling coil and the generating coil are connected in series with each other in the iV-plane and in opposite directions with respect to the rotation axis.

。FIG. 2 shows the inside of an axial gap to explain the principle of frequency power generation in a flat electric motor to which the present invention is applied. In other words, a normal flat electric motor consists of a stator section consisting of a bearing 2 and a yoke 3 perpendicular to the bearing 2, a multipolar magnet 4 magnetized in the axial direction along the circumference, a shaft 6, and these fixedly attached. The drive coil 1 is formed into a flat shape and is fixed to the stator part side in the axial gap between the yoke 3 and the multipolar magnet 4. In the 0-piece configuration, the rotor portion is rotatably supported by a bearing 2, and is also supported by a multipolar magnet 4.
The magnetic flux on the side of the axial air gap of i!
It's digging along the road. Therefore, when a drive current is applied to the drive coil 1, the rotor section including the multipolar magnet 4 rotates.

Ｎが８くなろ。As shown in the figure, radial line elements a8 parallel to the magnetized boundary of the multipolar magnet are arranged in an annular shape within the axial gap, and the end of each line element 8 is connected to the outer circular arc line element 11 and Generating coils 9 are provided which are alternately connected in series on the same plane using inner circular arc wire elements 12. As shown in Figure 3, each line element 8
Since the arc wire elements are connected alternately at each magnetization boundary of the multipolar magnet 4, an induced electromotive force is generated that alternates as the rotor rotates. At this time, the magnetic fluxes generated by the drive coil 1 and the multipolar magnet 4 are both substantially parallel to the rotation axis 6 because they share the yoke 3 that is perpendicular to the rotation axis 6. For this reason, the power generation coil 9 and the drive coil 1 only need to be located in the axially co-protruding Fi 15, and either of them may be placed on the yoke side. However, the arc wire elements 11 and 12 do not contribute to the generation of the induced electromotive force that alternates with the rotation of the rotor, and as a whole, they almost eliminate the magnetic flux generated by the drive coil around the rotation axis of one turn. When the drive coil is energized to form a surrounding coil, an associated induced electromotive force is generated. Therefore, the sum of the alternating induced electromotive force and the induced electromotive force caused by energization to the drive coil is output to the output terminal 13.14 of the generating coil 9, which is formed by connecting the line element 8 and each arcuate line element 1L12 in series. As a frequency generator accompanying rotation, S/
N becomes 8.

果を得ることができる。FIG. 1 shows an axial development view of an embodiment of a motor with a frequency generator according to the present invention. This embodiment is almost the same as that shown in FIG. 2, but the canceling coil IO is arranged in a circular shape along the arc wire ll, and the magnetic flux generated by the drive coil and the multipolar magnet are connected to each other. The generator coil 9 and the canceling coil 10 are connected in series, and the winding directions thereof are opposite to each other. There is. For this reason, the circular arc wire element 11. , the induced electromotive force at the canceling coil section and the induced electromotive force at the canceling coil section are in opposite phases and at almost the same level, so they cancel each other out, and a frequency signal with a good S/N is inputted to the output terminals 13 and 14. Ru. In Figure 1, arc line element ]l
An example is shown in which the canceling coil 10 is provided along the arc wire element 12, but if the arc wire elements 11 and 12 are electrically in series and both surround the magnetic flux generated by the driving chi h coil, the arc wire element 12 A similar effect can be obtained by providing a cancellation coil IO along the line.

By setting the location at the same pitch as the placement gap, the &! Since a portion having the same radius as the element 8 can be regarded as a power generation line element, the position of any line element 8 can be used as an output terminal.
