ABSTRACT:
A 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. Consequently, the effect of the present invention is able to be obtained by reducing the range of variation in the number of armature coil conductors that actually produce thrust.
