An electrical alternator is disclosed having a high output bobbin. The rotor assembly of the alternator includes a bobbin assembly having an expandable split or seam through a section of the bobbin assembly, a field coil that is wrapped around the bobbin assembly, and a pole assembly having an integrated hub for receiving the field coil wrapped bobbin assembly. The bobbin assembly can consist of either a single component or multiple components. The method for constructing the rotor assembly is also disclosed.

High output alternator bobbin

An alternator comprising an inner housing, an outer housing mounted over the inner housing and a plurality of o-rings positioned between the inner housing and the outer housing thereby creating a sealed flow chamber having a first plenum, an axial jacket, a second plenum, a first passageway interconnecting the first plenum and the axial jacket, a second passageway interconnecting the axial jacket and the second plenum, an inlet extending from the first plenum, and an outlet extending from the second plenum. The first and second plenums are disk shaped cavities extending diametrically across the alternator, and the axial jacket is an annular jacket extending around the alternator. The first passageway is located diametrically across from the inlet and the second passageway is located diametrically across from the first passageway. The outlet is located diametrically across from the second passageway.
