Abstract
A stator for a hybrid electric vehicle combines the best features of complete stators and segmented stators. The bobbins of a complete stator are modified to effectively widen the teeth and thereby reduce torque ripple. Each resin bobbin includes cavities on either side of the tooth. The cavities are filled with a magnetically conductive insert. In some embodiments, a single wedge shaped insert is installed on each side of each tooth. In other embodiments, multiple inserts of varying cross sectional area are installed on each side of each tooth.
