Design of Stator Core Shape of 'Magnetic Anisotropic Motor'

'Magnetic anisotropic motor', which is designed so as to draw the magnetic anisotropy characteristic of electrical steel to the maximum, is considered. GO steel is divided into some pieces and arranged in the stator core so as that main magnetic flux flows to follow the easy magnetization direction of GO steel. Through the parameter study to design the geometry of divided stator core by two-dimensional electromagnetic field analysis, iron loss reduction of 43% maximum is designed in comparison with the one of the conventional NO motor. In order to connect the teeth part and the yoke part mechanically, lapping connection is selected for realistic design for manufacturing even though the iron loss a little increases.
