A generator (10) for converting mechanical energy to electrical energy is described. The generator (10) includes a housing (12) which rotatably suppor ts a shaft (14). Two sets of coils, a set of primary coils (36), (38), (40), (42), (44), and (46), and a plurality of secondary coils (48), (50), (52), (54), (56), and (58), are fixedly supported by the housing wall (12). The primary and secondary coils are axially spaced apart from one another. Each of them is connected via a diode (64) to a respective one of the secondary coil s. A set of permanent magnets is fixed to the shaft (14) and positioned such th at the magnets are surrounded by the set of primary coils. A set of armature coils are also supported by the shaft (14) such that the armature coils are surrounded by the set of secondary coils. Current generated in the armature coils is collected using a brush and slip ring arrangement and is conducted out of the generator housing by wires. |
