Vertical Axis Wind Turbine

摘要

A turbine assembly is provided. The turbine assembly includes a plurality of sails and a generator assembly configured to convert rotation thereabout to power. A brake assembly may be provided. The brake assembly may include a magnet assembly that rotates with rotation of the plurality of sails, a conducting plate initially spaced-apart from the magnet assembly, and an actuator for translating the conducting plate relative to the magnet assembly during rotation thereof to thereby induce eddy currents that create a magnetic field acting on the conducting plate to impart a retarding force to control the rotational speed thereof. A control module is configured to control the actuator to adjust the spacing between the magnet assembly and the conducting plate in order to maintain the turbine assembly at a predetermined speed.

1. A turbine assembly comprising:
a plurality of sails; a generator assembly configured to convert rotation thereabout to power; and a brake assembly including a magnet assembly and spaced-apart conducting plate, wherein a spacing between the magnet assembly and the conducting plate is adjustable and one of the magnet assembly and spaced-apart conducting plate rotates with the plurality of sails, the other remaining fixedly secured relative to the plurality of sails; and a control module configured to adjust the spacing between the magnet assembly and the conducting plate in order to maintain the turbine assembly at a predetermined speed by inducing a retarding force to rotation of the plurality of sails.
