PURPOSE:To provide an outer-rotor-type motor capable of radiating heat easily without a need to take care of dust at a magnet part. CONSTITUTION:A shaft 24 is provided at the center of a rotor cup 22, and a magnet 26 is provided on an inner face of the rotor cup 22. The rotor cup 22 is so provided that a stator 12 is covered with the rotor cup 22. The stator 12 has an inner shaft 24 capable of rotating freely, and a space between the stator 12 and the magnet 26 is filled with magnetic fluid 38. |
