Abstract
In a linear motor, the drive coils (5a,5b) on the armature are formed by a number of sub-coils (6a.sub.1,6a.sub.2,6a.sub.3,6b.sub.1,6b.sub.2,6b.sub.3) oriented laterally of the motor axis subject to lateral magnetic fields generated by pairs of magnets (3a,3b) on the stator. The sub-coils are so arranged that the fields produced by the adjacent winding portions (8 and 9, 10 and 11) of an adjacent pair of sub-coils are of the same polarity.
