A linear motor has an armature; a moving member movable relatively to the armature; first and second magnetic pole tooth trains each having magnetic pole teeth magnetically coupled to one of two magnetic poles of the moving element, the first and second magnetic pole tooth trains being separated from each other in a direction substantially perpendicular to a moving direction of the moving member; and third and fourth magnetic pole tooth trains each having magnetic pole teeth magnetically coupled to the other of the two magnetic poles of the moving element, the third and fourth magnetic pole tooth trains being separated from each other in a direction substantially perpendicular to a moving direction of the moving member and the moving member being arranged between the first and second magnetic pole tooth trains and the third and fourth magnetic pole tooth trains.
