Abstract

The present invention provides a three-phase linear motor effective in the reduction of heating from coils. The three-phase linear motor is so constituted that a plurality of pairs of permanent magnets in which different magnetic poles are opposed to each other are arranged with a coil installation space in which three-phase coils are placed, positioned in-between; and the permanent magnets adjoining in the direction of movement are different from each other in magnetic pole. Coils 60U, 60W, and 60V in respective phases comprise two saddle coils 60A and 60B in which the short sides of a substantially rectangular coil are constituted as folded portions that form an angle of approximately 90 DEG to the straight portions of the long sides. The saddle coils are so combined that the two folded portions in each saddle coil face in opposite directions. At the same time, they are so combined that the two straight portions between the two folded portions of either saddle coil are brought as tight-contact straight portions into tight contact with the two straight portions between the two folded portions of the saddle coil in the other direction. The coils in the individual phases are so arranged that they are lined in series in the direction of movement, and the tight-contact straight portions of the coils in adjacent phases are brought into tight contact with each other.
