Abstract: A powdered magnetic material stator core with embedded stator windings and a method for its manufacture. Embedding the windings within a radially compacted powdered magnetic material stator core enables equivalent or better electromagnetic performance in a significantly reduced size. Radial compaction of the powdered magnetic material minimizes the distortion of the stator windings during compaction.

Abstract: A starter motor assembly is provided. A motor housing encloses an electric motor having a rotatable armature shaft. A planetary gear assembly is provided in a pinion housing, including planetary gears, a planet carrier, and a drive shaft. A pinion is engageable with the drive shaft for turning a flywheel of an engine. A non-load-bearing overrunning clutch assembly is provided, including an outer clutch piece removably fixed with respect to the pinion housing to be non-rotatable, and a rotatable inner clutch piece engaged with the planetary gears. Structure provided between the outer and inner clutch pieces allows rotation of the inner clutch piece in one direction and locks up the inner clutch piece in the other direction. When the starter motor assembly is energized, rotation of the armature shaft and planetary gears at a first rotational velocity rotates the inner clutch piece in the lockup direction.
