发明名称 LINEAR PULSE MOTOR
摘要 PURPOSE:To smooth the movement of a moving substance and to facilitate the restriction in the rotational direction, by forming axial grooves to stator and moving substance so as to get them to face in the diametrical direction between the stator and the moving substance. CONSTITUTION:A stator 1 of a linear pulse motor is cylindrically composed, on the inside diameter of which a pistonlike-shaped moving substance 2 is equipped and a metal 3 is equipped between the stator 1 and the moving substance 2. The stator 1 is composed so that iron cores wound over with winding 4 may axially be laminated. The moving substance 2 is composed so that permanent magnets 6 and iron cores 7 may be combined alternately. Axially long grooves 9a and 9b are respectively formed to the portion where the stator 1 faces the moving substance 2. The grooves 9a and 9b are composed so that they will turn into circular holes when they face the iron cores 5 of the stator 1 and iron cores 7 of the moving substance 2 respectively.
