PURPOSE:To prevent the sway of coil leads by fixing driving coils which oppose a permanent-magnet rotor on a disc-shaped resin plate on the outer portion of which extruded portion is provided and collecting the coil-lead wires the extruded portion on the resin plates and fixing them. CONSTITUTION:A motor 1 for directly driving the cylinder of a VTR is provided with a rotor 7 wherein a permanent magnet 9 is fixed on the upper surface of a rotor yoke 8 which is coupled to a shaft 3, and a stator wherein a driving coil 11 is provided on the bottom side of a stator yoke 10, and a Hall element 12 and printed board 13 are provided. The driving coil 11 is fixed to a plastic resin sheet 19 on the outer surface of which an extruded portion 20 is provided. The lead wires 29 of coils 21-28 are collected to said extruded portion 20, and fixed by heat or adhesive agent. Since the coil leads are fixed and perfectly protected, they are not cut out by vibration and the like, and the efficiency of fabrication work can be enhanced. |
