COMPACT STARTER-GENERATOR WITH COMMON CORE FOR MAIN AND EXCITER WINDING

摘要

A power system for a vehicle may comprise an electric machine attached to an engine of the vehicle. The electric machine may comprise only one stator core; a stator main winding wound on the one stator core; a stator exciter winding wound on the one stator core. The stator main winding and the stator exciter winding may be magnetically independent from one another even though magnetic-field-isolation material is not interposed between the stator main winding and the stator exciter winding.
