Abstract

PURPOSE:To improve the position detecting accuracy of a linear pulse motor by providing a detecting light passage passing from the front surface to the back surface of the groove of a stator, and mounting a light emitting element and a photodetector at a movable element so that one of the light emitting element and the photodetector is mounted at the front side of the stator and the other is disposed at the back side thereof. CONSTITUTION:Teeth 3 and grooves 4 are alternately formed on the stator 2 thereby forming a tooth-shaped member 5, a through hole is opened to pass from the back surface to the front surface at the groove 4, a photoconductor member 10 is inserted and fixed at the hole, thereby forming the detecting light passage 11. On the other hand, the light emitting element 12 and the photodetector 13 are so mounted at the movable element 1 that the element 1 is disposed at the upside of the passage 11 and the photodetector 13 is disposed at the downside of the passage 11. The position of the movable element 1 can be detected by counting the pulses outputted from the photodetector 13. Thus, the position can be precisely detected.
