  • Publication number: 20110241630
    Abstract: An electric power generation system is provided, including a generator having a plurality of stages engaged by a prime mover; and a plurality of branches for connecting the stages to an electrical load, each of the branches having a switch for connecting or disconnecting the branch to the stages. Power from a prime mover, such as a turbine, is sent by a controller to one or more of the branches as appropriate to handle the power level generated.

  • Publication number: 20100090553
    Abstract: A polyphasic multi-coil generator includes a driveshaft, at least first and second rotors rigidly mounted on the driveshaft so as to simultaneously synchronously rotate with rotation of the driveshaft, and at least one stator sandwiched between the first and second rotors. The stator has an aperture through which the driveshaft is rotatably journalled. A stator array on the stator has an equally circumferentially spaced-apart array of electrically conductive coils mounted to the stator in a first angular orientation about the driveshaft. The rotors and the stator lie in substantially parallel planes. The first and second rotors have, respectively, first and second rotor arrays.

A stator array on the stator has an array of electrically conductive coils mounted to the stator in a first angular orientation about the drive shaft. The rotors each have an array of magnets which are circumferentially equally spaced around the rotor and located at the same radially spacing with respect to the centre of the rotor and the drive shaft at a first angular orientation relative to the drive shaft. The arrays of magnets on adjacent rotors are off-set by an angular offset relative to one another.
