Abstract

PURPOSE:To increase the thrust of a linear motor by opposing a pair of field magnets arranged alternately with N- and S-poles, arranging a plurality sets of drive coils in which the first and second conductors are connected in the gap, thereby composing the motor. CONSTITUTION:Field magnets 10, 10' arranged longitudinally with N-, S-poles so that the adjacent poles become different polarity are oppositely disposed at the same polarity at the gap, the first and second conductors 18a, 18b wound with coil unit 12 of long plate shape made of magnetic material are disposed in the gap longitudinally isolated in the opening width of the poles, and connected to dispose a plurality sets of drive coils 18. A linear motor is formed with any of field magnet side and drive coil side as a moving element. Accordingly, the connecting part between the drive coils 18 which do not contribute to the thrust is only one conductor, thereby increasing the thrust.
