The present invention includes a stator core, a bobbin made of an insulating material which surrounds the outer surface of the stator core, and a coil which winds the outer surface of the bobbin. The stator core comprises an integration-type core part which is integrated by metal powder and around which the coil is wound, and a stack-type core part which is formed by stacking a plurality of steel pieces, connects the stator cores to interconnect the stator cores, and is combined with the integration-type core part. So, manufacturing costs can be reduced and the performance of a motor can be improved. |
