<p>A stator comprises a housing made of a magnetic conductive material; a plurality of magnets fixed on the housing; and a magnet holder which is attached to one end of the housing in order to fix the magnet on the stator housing. The magnet holder includes a main body which axially touches the end of the housing, and a plurality of locking structures which extend from the main body to be inserted into the stator housing. Each of the magnets is locked between two adjacent locking structures. A plurality of cutouts are formed in the stator housing, and a plurality of bumps are formed on an outer circumferential surface of the main body of the magnet holder to be engaged with corresponding cutouts. Each of the locking structures includes a wedge-shaped inner end which is inwardly engaged with each of the magnets such that the magnet is prevented from moving inward.</p> |
