OUTER ROTOR-TYPE FAN MOTOR AND METHOD FOR MAGNETIZING MAGNET APPLIED THERETO |
摘要 |
An outer rotor-type fan motor and a method for magnetizing a magnet applied thereto. The outer rotor-type fan motor comprises a rotation shaft; a stator disposed outside the rotation shaft; a fan having a hub and blades formed on the hub, the hub covering the stator with a predetermined gap; and a magnet disposed on an inner surface of the hub and spaced from the stator with a predetermined gap, wherein the magnet is an isotropic magnet magnetized to have a pole anisotropy. Accordingly, a cogging torque and noise are reduced without reducing a back-electromotive force, thereby obtaining a high efficiency.
