グモータ。 A permanent magnet held by a stator iron core having a plurality of magnetic poles implanted radially outward on the outer periphery of an annular yoke and pole teeth provided at the tips of the magnetic poles, and a winding wound around each of the magnetic poles. In an outer rotor type stepping motor comprising a stator made of wires and a rotor having pole teeth facing the pole teeth of the stator with a gap therebetween, the permanent magnets are connected to a circle of the stator iron core. An outer rotor type stepping motor characterized in that it is formed of an annular portion corresponding to the annular yoke portion and a foot portion corresponding to the magnetic pole portion of the stator core.
