摘要: A plurality of permanent magnets are embedded at predetermined pitches &tgr;p in a longitudinal direction in a field yoke composed of a magnetic substance so that adjacent magnet poles have opposite polarity, and a plurality of electromagnets, which have magnetic pole pitches &tgr;e≈(2n+1)&tgr;p of preset intervals provided that n is 0, 1, 2, . . . , which are disposed at predetermined pitches &tgr;g=(2s+1/m)&tgr;e in the longitudinal direction of the field yoke provided that m is a number of exciting phase and s is 1, 2, 3, . . . , and which are separated from the field yoke by a predetermined gap while opposing to the field yoke, are provided. The field yoke is driven by successively exciting the electromagnets.
