Patent ID: 8922077

Claim:
An outer rotor-type motor, comprising: a stator being constituted by a plurality of stator units, which are concentrically stacked around a bearing section and in each of which an air-core coil formed by winding a magnet wire is sandwiched between stator yokes having comb-shaped magnetic pole teeth; an output shaft being pierced through the bearing section; a rotor having a rotor yoke, which includes a permanent magnet having magnetic poles facing the magnetic pole teeth and which is capable of rotating together with the output shaft; lead terminals of a driving circuit for energizing the coils to drive the motor; a plurality of stator guide plates, which are formed into a ring shape and insulation-coated, are fitted on an outer circumference of a bearing housing, which is formed into a cylindrical shape and capable of rotatably holding the output shaft, to form a plurality of bobbins in the axial direction, the coils, which are formed by winding the magnet wires, are respectively attached to the bobbins, and the coil leads are extended toward outside of the adjacent coils via a wiring space formed from the inner side of each of the stator guide plates to the outer side thereof; and coil leads, which are extended outward from the inner side of each of the coils via a gap between the outer circumference of the coil and the magnetic pole teeth, are electrically connected to the lead terminals, wherein each of the stator yokes is formed into a ring shape and constituted by a plurality of yoke parts, the stator yokes, which are formed by combining the yoke parts, surround outer circumferences of the coils, each of the stator guide plates includes: a slit having erecting walls, which are continuously formed from the inner side to the outer side; a guide section being located on the radially opposite side to the slit, the guide section being projected in the same direction as the erecting walls are projected; and a notch being formed at the outer end of the guide section, and the coil leads are extended outward via a groove, which is formed by overlapping the guide section and the erecting walls of the adjacent stator guide plate, and the coil leads are wired along the outer circumference of the adjacent coil via the notch and the erecting walls.
