Abstract

PURPOSE:To improve accuracy of finishing and mass-producibility by inverting and laminating a fixed number of single plates, to which upper and lower magnetic pole teeth are punched so that distances from the center line of a moving piece each differ, in the moving direction of the moving piece. CONSTITUTION:An upper stator magnetic pole 42 and a lower stator magnetic pole 43, which have an outer circumference 41 of dimensions contacting with an inner circumference of a housing 2 and a lower end surface 42' and an upper end surface 43', which are projected to the inside from the upper and lower sections of the outer circumference 41 and distances L and M thereof from the center line 40 equally dividing a plane shape into two sections up and down each differ, are punched from a magnetic sheet. The punched single plates are laminated in the moving direction of a moving piece 1, being alternately rotated in 180-degree arcs in a laminating surface every fixed number, and a magnetic pole 4 with teeth of a stator is manufactured. A motor is formed in such a manner that left and right two poles 4 with teeth of the stator are disposed through permanent magnets 5, and the moving piece 1, upper and lower both surfaces thereof have teeth, is mounted movably.
