Linear motor

A linear motor including a plurality of linear motor structures connected together, at least one of the plurality of linear motor structures being an improved linear motor structure, said improved linear motor structure comprising:

• a first member tapered relative to a traveling direction thereof to provide a surface slanted relative to the traveling direction toward one end of said first member;
• a second member having a surface that is opposed to the slanted surface of said first member and slanted relative to the traveling direction at an angle corresponding to a slanted angle of the slanted surface of said first member;
• a field pole producing section that produces field poles on the slanted surface of one of said first member and second member;
• and
• an armature section provided another of said first member and second member and including armature windings, said armature section producing electromagnetic poles corresponding to electric currents passed through said armature windings,
• wherein the one of said first member and second member moves relative to the other of said first member and second member in response to excitation of said armature windings.
