  • Variable input synchronous output drivetrain for wind turbine
    Patent number: 8845471
    Abstract: A wind turbine drivetrain is disclosed. The wind turbine drivetrain includes a planetary gearbox. The planetary gearbox includes a carrier rotatably driven at a first input rotational speed, and a planet gear rotatably mounted to the carrier. The planetary gearbox further includes a sun gear rotatably coupled to the planet gear, and a ring gear rotatably coupled to the planet gear. One of the carrier, the sun gear, or the ring gear is selectively rotatably driven at a second input rotational speed. The wind turbine drivetrain further includes an output gear rotatably driven by the planetary gearbox at an output rotational speed, and a motor selectively operable to rotatably drive the one of the carrier, the sun gear, or the ring gear.
