  • Publication number: 20060066110
    Abstract: The machine includes a rotor with an inner rotor core and an outer rotor core and a double-sided stator with an inner stator side and an outer stator side. The double-sided stator is concentrically disposed between the inner rotor core and the outer rotor core of the wind turbine generator. The double-sided stator is configured to enable at least a portion of magnetic flux to be shared between the inner stator side and the outer stator side. Examples of particularly useful embodiments for the machine include wind turbine generators and ship propulsion motors.

  • Publication number: 20050116689
    Abstract: A method to start a combined unit gas turbine and electrical unit having a static start drive including the steps of: applying a variable frequency voltage from the static start drive to a winding of the generator to accelerate the combined unit to a turbine self-sustaining speed; accelerating the combined unit beyond the self-sustaining speed by applying torque generated by the turbine, and as the combined unit accelerates to a synchronous speed, applying a braking torque from the static start drive to steady the combined unit at the synchronous speed.

  • Patent number: 6015227
    Abstract: A foam extrusion assembly having a melt region wherein a plurality of material pellets are melted and mixed by a mixing assembly with a blowing agent introduced via an agent addition assembly. The foam extrusion assembly further includes a heat extraction region structured to extract excess heat from the mixture of melted material pellets and blowing agent such that the mixture achieves an extrudable temperature. The heat extraction region includes an elongate barrel having at least one inlet and at least one outlet, the inlet being structured to receive the extrusion mixture therethrough for passage into the barrel wherein a heat extraction structure cooperatively disposed with the barrel draws heat therefrom. An extrusion screw is disposed in the barrel and includes at least one screw flight structured to rotate within the barrel and urge the extrusion mixture towards the outlet of the barrel where a die is disposed in order to form the finished product.
