The first and the second magnet rows are arranged at both sides of the first coil row so as to sandwich it. Each coil of the first coil row substantially has not a core made of a magnetic body, and the motor substantially has not a yoke made of a magnetic body for forming a magnetic circuit. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
