Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A stator for a high efficiency motor, the stator comprising: a stator core partitioned into a center hole and inner spaces, the stator core including a yoke portion and a plurality of teeth; coils coiled around the plurality of teeth, respectively; filling parts filling the inner spaces, respectively; and a pair of core covers coupled to upper and lower surfaces of the stator core, respectively, wherein the filling parts are configured to prevent magnetic flux leakage from occurring between the coils coiled around the plurality of teeth, and wherein the filling parts and the core covers are made of filling powder provided by coating a surface of soft magnetic powder with an insulating layer made of alumina. 2. The stator of claim 1 , wherein the stator core is configured such that a plurality of split cores having respective back yokes and teeth is radially disposed to form the center hole and the inner spaces. 3. The stator of claim 2 , wherein each back yoke comprises a coupling protrusion formed on a first side thereof and a coupling groove formed on a second side thereof.
