PURPOSE: To realize a low-cost and high-reliability motor by reducing the windage loss due to the rotation of its rotor. CONSTITUTION: A motor comprises a rotating shaft 1, a rotor 3 provided rotatably at the external circumference of the rotating shaft 1, a polygon mirror 9 provided at one end side of the rotating shaft 1, stator core 6, coil and magnet 4 for rotating the rotor 3, a bearing means for rotatably supporting the rotor 3 and a housing 15 arranged at the position opposed to the rotor 3. |
