As a result thereof, the position of the moving body is calculated based on a detection result of the magnetic field detected by the magnetic detector. A linear scale or the like as in an optical method is not required separately to constitute the position detecting means compactly and inexpensively, since the position detecting means can be constituted by using the existing fixed magnet for a linear motor.  <P>COPYRIGHT: (C)2003,JPO
