PURPOSE:To eliminate the need for a magnetic substance substrate, and to manufacture a low-cost motor having excellent efficiency by housing a terminal section for an electronic part for a printed board into a small hole for reducing the eddy currents of a stator yoke. CONSTITUTION:An armature 22' is constituted in such a manner that a printed board 35 is arranged onto a strut 13a, a stator yoke 36 is fixed onto the board 35 and coreless armature coils 17, 18 are disposed onto the stator yoke 36. A plurality of small holes for reducing eddy currents are formed to the stator yoke 36. Terminal sections for low-cost discrete electronic parts 16' organizing a driver circuit are soldered to a wiring pattern on a top face through the holes in the printed board 35. Soldering sections 44 projecting from the top face of the terminal sections intrude into the small holes in said stator yoke 36, thus fast sticking the stator yoke 36 and the printed board 35. |
