PROBLEM TO BE SOLVED: To facilitate arrangement of magnets for flux increase in a gap, concentration of flux in a gap, the determination of the shape and structure of a core for improvement of productivity and controllability at the start and reduction in the change-over loss at polarity change in a high revolution state by noting that the improvement of flux density in a gap between the rotor and stator of a motor or a generator is directly related to improvement in performance. SOLUTION: In order to increase magnetic flux in a gap, radial slots into which magnets are inserted are formed in respective pole cores, so as to facilitate the adjustment of lengths of the magnets in the radial directions. For the increase in the intensity of flux in particular, a magnet which fills up the full length of the slot is used. Next, by employing a detachable construction, the performance of a motor or a generator can be changed or adjusted easily. Since a single magnet structure has limitation from a viewpoint of improvement of the construction and magnetic force, a plurality of magnets are combined effectively for the respective poles in order to increase the magnetic force in the gap. |
