Abstract: A flying device includes a plurality of rotary vanes, a motor element serving as a driving source for each of the plurality of rotary vanes, the motor element driving and rotating a main shaft of the rotary vanes, and a drive circuit. The motor element includes a stator, a rotor, and a pair of bearings. The stator includes a stator core having an annular yoke and a plurality of teeth projecting inward from the annular yoke, and stator windings wound respectively around the plurality of teeth of the stator core. The rotor includes a permanent magnet of a cylindrical shape located inside the stator core via a gap, the permanent magnet being positioned counter to the plurality of teeth, a rotor yoke in contact with a cylindrical inner wall surface of the permanent magnet, and a shaft pivotally supported at an axis of the rotor yoke, the shaft being connected to the main shaft. The pair of bearings pivotally support the shaft to allow the shaft to rotate freely, and are located respectively on both sides of a direction of a rotating shaft of the rotor. The permanent magnet has anisotropically arranged magnetic poles, and a number of the magnetic poles is P representing an even number. The permanent magnet is configured such that the rotor yoke is smaller in weight than the permanent magnet. The drive circuit controls a stator current supplied to the stator windings.
