Electromagnetic rotating machine

An electromagnetic rotating machine comprising:

• a rotating body and a fixed body, and driving the rotating body by using electromagnetic force which is produced by a mutual induction effect between an armature coil and an excitation coil,
• wherein the armature coil is disposed on an outer circumference of the rotating body, and the excitation coil is disposed on an inner peripheral surface of the fixed body which the armature coil faces, and
• wherein the excitation coil is configured from n (≧2) numbers of split excitation coils, and the armature coil is configured from one or more split armature coils, the split armature coil intersecting in the vicinity of a central portion thereof and being closed coil that forms symmetry with respect to centerline including the intersection thereof, and the vicinity of a central portion of one of the split armature coils overlaps with the vicinity of a central portion of one of the split excitation coils so that the electromagnetic force is produced, and at that time the split armature coil overlaps with other split excitation coils at both sides of the split armature coil.
