Claims

[Scope of utility model registration request]

(1) Place flat permanent magnet pieces magnetized in the thickness direction on the inner surfaces of opposing yokes so that the opposite polarities are different and the adjacent polarities are different so that the width of the magnet pieces is the same as the width of the magnet pieces. A stator arranged in the longitudinal direction with an interval of A moving coil assembly is provided in which a plurality of moving coils are assembled by being shifted by the width of the magnet piece in the longitudinal direction, and a bending portion is provided at the top and bottom of the moving coil assembly. A top plate portion is provided with a groove for attaching a current collecting brush connected to the terminal of the moving coil and for holding an overhead wire that contacts the current collecting brush and has a required power distribution pattern, and the magnet piece is provided. A moving coil type linear motor comprising a housing integrally extruded with a side plate portion provided with a groove for holding the yoke and a side plate portion provided with a rail piece covering the upper and lower sides of the magnet piece.

(2) The housing is made of an extruded aluminum or resin material, and the overhead wire is made of a flexible printed circuit board, and the overhead wire has a bent portion at one end, and this bent portion is formed between one end surface of the housing and an end surface of the housing. The other end of the overhead wire is inserted and held in the groove provided in the top plate part, and the yoke is inserted and held in the groove provided in the both side plate parts, and the other end of the overhead wire is held in the groove provided in the top plate part. A moving coil type linear motor according to claim 1, wherein the moving coil type linear motor is fixed in the housing by the end cover and another end cover fitted to the other end face of the housing. .
