<p>An outer rotor type fan-motor and a magnetizing method of a magnet for the outer rotor type fan-motor are provided to reduce the number of processes and to improve an inner volume of a refrigerator using the outer rotor type fan-motor by not using a rotor yoke or a back yoke in mounting the motor on a fan. An outer rotor type fan-motor includes a rotation axis(110), bearing assemblies(115,117), a stator(112), a fan(120), and a magnet(113). The bearing assemblies rotatably support the rotation axis. The stator is installed outside the bearing assemblies. The fan includes a hub(124) and a blade(122). The hub has an axial fixing unit to surround the outside of the stator apart at a predetermined interval and to fix the rotation axis. The blade is formed on the hub. The magnet is spaced apart from the outside of the stator at a predetermined interval and installed on an inner surface of the hub. The magnet is magnetized to have polar anisotropy as an isotropic magnet.</p> |
