ABSTRACT:
In one embodiment of the present invention, a rotor of a "claw pole" alternator includes first and second pole pieces with intermeshing fingers. Magnetic inserts are provided made preferably of permanent magnet material. Each insert extends under the end of a pole finger of the rotor and has two surfaces which face radially outward from the rotor. The resulting design provides improved power output and reduced acoustic noise when compared with conventional alternators, in a design which is durable and amenable to mass production.
