PURPOSE:To mass produce motors for producing rotary speed signals with high accuracy by integrally securing a plurality of drive coils through resin molding and forming a flat face at the outer circumference of a magnet then arranging a FG multi-pole magnetizing section at the outer circumference of the surface facing with a coil and securing a generating substrate onto the flat face. CONSTITUTION:A plurality of drive coils 9 are integrally secured with a stator yoke 7 and a printed board 8 through insert resin molding and a flat face facing with a magnet 4 is formed by the resin mold section 20 and the coil 9. A generating substrate 10 is secured onto the flat face while facing with a FG multi-pole magnetizing section 4a. By such arrangement, motors for producing rotary speed signals with high accuracy can be mass produced. |
