Title:
PERMANENT MAGNET ROTOR ALTERNATOR
Document Type and Number:
WIPO Patent Application WO1997008432
Kind Code:
A3
Abstract:
A permanent magnet rotor alternator is disclosed having a one-piece, rotor hub+544 flywheel+544 starting gear. Three high remanence ceramic permanent magnets provide a rotor having a contiguous ring of twelve alternating poles which allows for higher alternator efficiency. The magnets are ceramic and are adhesively bound to the rotor hub, which is driven by an extended crankshaft. The rotor rotates within a wound stator assembly of which the laminated stator core is a part of the alternator's frame assembly, and thus, serves as a shield should a rotor magnet come loose.
