PURPOSE:To enable to smoothly rotate by arranging many armature coils without superposition. CONSTITUTION:Armature coils 14A, 14B group which are wound in (2n-1) times of the poles of a field magnet at the central angle of conductor units 14Ab, 14Bb which contributes the torque produced are fixed axially in two stages on the inner surface of a cup which is opposed to a field magnet. Armature coils 14A group, 14B group are cylindrically arranged at an equal interval so as not to be superposed peripherally. Position detectors 15A-1, 15A-2, 15A-3 for the coils 14A-1, 14A-2, 14A-3 are arranged between the conductor units 14Bb which contribute to the torque generated from the one armature coils 14B-1, 14B-2, 14B-3, and the one side position detectors 15B-1, 15B-2, 15B-3 are similarly disposed between the conductor units 14Ab which contribute the torque generated from the coils 14A-1, 14A-2, 14A-3. |
