Title: MOTOR AND ROTARY BLADE APPARATUS
Abstract:
[Problem] Provided is a motor having a structure in which blades are easy to attach, and the rotation center of the blades is easy to conform to the rotation center of a rotor. [Solution] A motor according to one embodiment of the present invention is a motor to which blades are attached, wherein the motor is provided with: a base member; a stationary shaft fastened to the base member, the stationary shaft having as a center a center axis extending in the vertical direction; a rotor having a magnet positioned farther outward in the radial direction than the stationary shaft; a stator attached to the base member, the stator facing the magnet with a gap interposed therebetween; and a bearing for supporting the rotor so that the rotor can rotate in relation to the stationary shaft. The rotor has a blade attachment part to which the blades are attached, and at least a portion of the blade attachment part is positioned above the stationary shaft.
