Abstract

PURPOSE: To improve positioning accuracy, by carrying out metal injection molding applied with fine machining including a moving chip and teeth provided on a stator.
CONSTITUTION: Teeth 11 are formed at the tip of an upper yoke 1 while a non-circular coupling shaft 13 is formed on the underface and a linear projection is provided axially on the outer circumference and supported in a supporting hole 16 made in a lower yoke 7. An excitation coil 2 formed by winding a conductive wire spirally and provided with lead wires is inserted into the upper yoke 1. Teeth are formed in comb-shape to be slightly wider than the upper yoke 1 at a portion of a moving chip 3 made from magnetic material facing with the teeth 11 at the tip of the upper yoke. A permanent magnet 4 is placed in the center of the lower yoke 7 and constitutes a magnetic circuit in combination with the moving chip 3 through the upper yoke 1. The upper yoke 1 is manufactured through metal injection molding including the teeth 11 at the tip.
