Zusammenfassung:	The linear direct current motor is described that is able to maintain stable thrust at all times regardless of changes in the relative positions of the primary and secondary sides. The endmost magnetic poles of a field magnet are used as non-detected magnetic poles with respect to magnetic pole discrimination elements, while these non-detected magnetic poles are used only as driving magnets for generation of thrust, thereby reducing the range of variation in the number of conductors of armature coils that actually generate thrust. In addition, since the drive current supplied to the armature coils is in the form of a constant current, changes in thrust can be further reduced.
