Abstract:
An air blower comprises a motor including a rotor, a stator, and an output shaft fixed to the rotor, a fan that rotates by receiving power from the motor, a casing that retains the motor and the fan, and a handle provided at the casing. The rotor has a coil disc including a plurality of substantially annular coils arranged in the circumferential direction around the output shaft as viewed from the direction of the axial line of the output shaft. The stator has a magnetic flux generating mechanism that generates magnetic fluxes passing through the coil disc in the direction of the axial line of the output shaft.
