Abstract:
An outer-rotor motor includes a stationary portion, a rotating portion, and a bearing mechanism arranged to support the rotating portion such that the rotating portion is rotatable about a central axis extending in a vertical direction with respect to the stationary portion. The stationary portion includes a stator, a mounting plate, and a circuit board. The rotating portion includes a shaft, a rotor holder, and a rotor magnet. The mounting plate includes a projecting portion arranged to project radially. The outer-rotor-motor further includes a guide structure connected with the projecting portion. The guide structure is arranged to extend axially, radially outside the rotor holder. A leadwire is electrically connected to the circuit board, and is guided along the guide structure. Provision of the guide structure, which is arranged to guide the leadwire radially outwardly of the rotor holder, contributes to preventing a contact between the leadwire and the rotor holder.
