An electrical generator (10) having particular utility as a vehicle alternating generator includes a planetary gear set (32) for providing counter rotation of a pair of fields (80,82) with respect to a coil (60) so as to provide high power output even at relatively low speeds of driving without providing excessive rotational speed at high speeds of driving. In one embodiment, the planetary gear set (32) includes a ring gear (36), a sun gear (44), and a planet carrier (50) whose planet gears (52) rotate about associated axes parallel to the rotational axis A about which the planetary gear set operates. In another embodiment, the planetary gear set has a bevel gear construction including first and second bevel gears (36',44') rotatable about the rotational axis of the planetary gear set and meshed with bevel type planet gears (52') of the planet carrier (50') so that the two field (80',82') have counter rotation with respect to each other at the same rotational speed. Both embodiments of the generator (10,10') have a stationary planet carrier (50,50') so that the other gears meshed with the planet gears (52,52') thereof rotate about the rotational axis A to provide the counter rotation of the fields (80,80' and 82,82') with respect to the coil (60,60').
