<p>A pole arrangement of a motor (1) includes a plurality of permanent-magnet main poles (2) disposed annularly at equal intervals on the inner periphery of a yoke (3), a plurality of auxiliary poles (4) disposed between adjacent two of the main poles (2), and a plurality of magnet holders (6) disposed between adjacent two of the main poles (2). Each the magnet holder (6) is comprised of resilient stopper means (62) for pressing the main poles (2) in the circumferential direction, and each the auxiliary pole (4) is held between the pair of resilient stoppers (62). <IMAGE> <IMAGE></p> |
