ABSTRACT:
A moving-magnet type linear d.c. brushless motor having plural moving elements on a traveling track, and including a stator armature on the traveling track; n moving elements, each including a thrust-generating field magnet having P contiguous magnetic poles of alternating N and S polarity, where n is an integer greater than 1 and P is an integer of at least 1, the moving elements having one side facing the stator armature and traveling separately and independently along the traveling track; a plurality of position-detecting magnets, each corresponding to a different one of the moving elements and having P magnetic poles of N and S polarity at in-phase positions of substantially the same pitch relative to the poles of the thrust-generating magnets; and position detecting means including a group of position sensors corresponding to each position-detecting magnet for generating an electric current in the stator armature to move the moving elements in predetermined directions separately and independently, each position sensor detecting the magnet poles of only the corresponding position-detecting magnet.
