Title: The Innovations of John Gjertsen, Sr. in Wind Power Technology
Introduction
John Gjertsen, Sr., a notable inventor located in Bedford, Massachusetts, has made significant contributions to the field of renewable energy with his innovative windpower system. With one registered patent, Gjertsen focuses on enhancing the efficiency and reliability of wind power generation.
Latest Patents
John Gjertsen, Sr. holds a patent for a groundbreaking windpower system. This invention involves a support structure and a turbine with a shaft rotatively mounted to the support. The turbine features variable pitch blades, which are controlled by the differential motion of a rotary control shaft that is coaxial with the turbine shaft. This design allows for blade pitch adjustment using a stationary motor, thus eliminating the need for slip rings or any wear-prone couplings. In instances of power failure, the rotary motion of the control shaft is prevented, enabling the turbine blades to feather solely due to the force of the rotating turbine. Moreover, when the turbine generates electrical power, an induction generator is coupled to the turbine shaft, which monitors the generator’s speed to optimize the turbine blade pitch. This ensures maximum generator output power at low wind speeds and maintains rated output power as wind speeds increase beyond the machine's rated threshold.
