Abstract

See full text

An electric power generation system may be constructed of multiple similar generator modules arranged between a rotor and a stator. The rotor may be coupled to and/or integrated with a turbine that is configured to rotate in the presence of a fluid stream such as wind or water. Each generator module may have a rotor portion configured to generate a magnetic field having at least one characteristic that changes with respect to the rotational speed of the rotor. Each generator module may further have a stator portion configured to generate an alternating electric current responsive to the magnetic field. The generated electric current may be controlled by the stator portion of the generator module in order to magnetically control the rotational speed of the rotor and the turbine. Separation between the rotor and stator portions of the generator module may be magnetically maintained.
