Claims

[Scope of utility model registration request]

A motor magnet magnetized to a single pole in the axial direction is fixed to a rotating shaft to form a rotor, and a stator consisting of a coil wound around a core of magnetic material is placed in a position facing the magnetic pole surface of the rotor magnet. However, in a single-pole motor in which the magnetic circuit between the rotor magnet and the stator is configured so that the magnetic flux generated from the rotor magnet intersects only with the coil portion on the rotor side on the opposing surface of the stator core, A single-pole motor characterized in that a plurality of wound coils are arranged on the stator circumference to form a stator section.
