Abstract
A stator for a high efficiency motor, and a manufacturing method of such a stator, the stator including a stator core partitioned into a center hole and inner spaces. The stator core includes a yoke portion and a plurality of teeth. The stator includes coils coiled around the plurality of teeth, respectively, and filling parts filling the inner spaces, respectively. The filling parts are configured to prevent magnetic flux leakage from occurring between the coils coiled around the plurality of teeth.
