Abstract: A linear motor that displaces a tubular body and a rod relative to each other in an axial direction includes teeth arranged in the axial direction so as to project from an inner peripheral surface of the tubular body, slots formed between adjacent teeth, coils disposed in the slots, and permanent magnets provided in the rod and arranged in the axial direction. The coils are constituted by one or more first phase coils, one or more second phase coils, and one or more third phase coils. The first, second, and third phase coils are provided in the axial direction such that the first phase coil and the second phase coil are disposed at respective ends the tubular body. A total number of coil windings of the third phase coils is set to be smaller than a total number of coil windings of the first phase coils and a total number of coil windings of the second phase coils.
