たり、あるいは上記導体部５ａ。The curved width of the portions 5a and 5a' is formed by winding to have a width tltilj2n-1 (n is a positive ritual above one seed) times the magnetic pole width of the field magnet 7, which will be described later. now,
In this embodiment, the armature coil 5 has a bending width of n21, that is, the bending width of the conductor portions 5a and 5a' contributing to the thrust is approximately equal to the magnetic pole width of the field magnet 7. ing. In the dark, the magnetic poles of the field magnet 7 are skewed N 58 , or the conductor portion 5a.

向するプリント基板１３面に配設している。When the armature coil 5 is formed by skewing the armature coil 5a', the above condition j2n-1j is slightly different, but such a case also falls within the spirit of the present invention. Conductor portions 5b and 5b' perpendicular to the conductor portions 5a and 5a' are conductor portions that do not contribute to the thrust force V. A printed circuit board 13 is fixedly mounted on the armature surface, which is composed of a group of 5 armature coils and faces the field magnet 7. Figure 11 ¥1 to Figure 3, Figure 5
