Abstract
A polyphase rotary induction machine for use as a motor or generator utilizing a single rotor assembly having two series connected sets of rotor windings, a first stator winding disposed around the first rotor winding and means for controlling the current induced in one set of the rotor windings compared to the current induced in the other set of the rotor windings. The rotor windings may be wound rotor windings or squirrel cage windings.
Claims7
A rotary induction machine electric power generating system comprising a single rotor assembly, a first set of rotor windings fixed to said rotor assembly, a second set of rotor windings fixed to said rotor assembly at a location spaced from said first rotor windings, means for connecting each winding of said first rotor windings in series with a winding of said second rotor windings, a first stator winding disposed around said first rotor windings, a second stator winding disposed around said second rotor windings, means associated with one of said stator windings for controlling the current induced in one set of said rotor windings with respect to the current induced in the other set of rotor windings, means for connecting an alternating current source to said first and second statur windings, and wind turbine means for rotatably driving said rotor assembly, said single rotor assembly together with said rotor and stator windings providing unitary means for initiating rotation of said wind turbine means and for generating electrical power with a frequency equal to that of said alternating current source irrespective of the speed of rotation of said single rotor assembly.
