Claim 0:
1. A linear motion motor on which a three-phase current is supplied, comprising:
a first mover that aligns and holds a plurality of permanent magnets in a longitudinal direction;
a first stator including 6n (n is an arbitrary natural number) teeth aligned in the longitudinal direction to face the first mover and 6n windings wound around the respective teeth;
a second mover that aligns and holds a plurality of permanent magnets in the longitudinal direction;
a second stator including 6n (n is an arbitrary natural number) teeth aligned in the longitudinal direction to face the second mover and 6n windings wound around the respective teeth; and
a bonding member for bonding the first mover and the second mover arranged in parallel, in which
the opposite permanent magnets of the first mover and the second mover are arranged with a phase difference of π/2 in an advancing direction of the both movers, and
currents with the phase difference of (1+6m) π/3 or (2+6m) π/3 (m is an arbitrary integer) are supplied to the opposite windings of the first stator and the second stator.
