| description | A magnet and a method of fabricating the same are provided, including a first fine milling step and a second fine milling step, in which a rotational speed of a classifying wheel in the second fine milling step is higher than a rotational speed of a classifying wheel in the first fine milling step, and a milling pressure in the second fine milling step is lower than a milling pressure in the first fine milling step. The powder distribution and the powder morphology of the magnet are improved by adding the second fine milling step after the first fine milling step, thereby improving the magnetic properties of the magnet. Moreover, a required density of green compact which is pressed and formed is further limited, so the magnet is not broken during the production process and can be easily formed. |
