SYNCHRO-SYM is a patented, fully integrated electric machine circuit and control architecture comprising a multiphase wound-rotor doubly-fed electric machine circuit topology and a brushless, bi-directional, sensor-less, and automatic controller, called brushless real time emulation controller (BRTEC), that uniquely guarantees brushless, contiguous and symmetrically stable, "synchronous" operation during motoring and generating from sub-synchronous to super-synchronous speeds, including at absolute or about synchronous speed.


No different from any other electric motor system, SYNCHRO-SYM comprises an electric machine entity (i.e., the actual motor/generator or electric machine) and an electronic power controller (i.e., the motor drive) for practical variable speed, high efficiency operation but that is where it ends. Unlike the century old componentized circuit and control architecture of all other electric machine systems, including state of art permanent magnet electric machine systems, the simple operating physics of SYNCHRO-SYM's patented integrated electric machine circuit and control architecture eliminates the extraneous loss, cost, size, and complexity of “passive” rotor assembly components, such as permanent magnets, reluctance saliencies, field windings, and induction squirrel cage windings, by brushlessly retrofitting within the same physical footprint, the additional active power of another “active” winding set on the rotor assembly as already provided by the stator “active” winding set. As a result, SYNCHRO-SYM is the only electric machine system with the magnifying electromagnetics of a symmetrical (i.e., dual ported) transformer circuit topology that allows 1) the rotor to actively contribute to electromechanical power production and conversion (in addition with the elemental stator assembly) and 2) up to four times more peak torque and power density at up to halve the cost and twice overall efficiency as all other electric machine systems, including rare earth permanent magnet electric machines. Note: High peak torque (as only provided by SYNCHRO-SYM) offers a fully integrated magnetic gear (or direct drive) electric vehicle propulsion systems.


As the only practical electric machine with the rotor assembly "actively" contributing to the electromechanical energy conversion process, the fully electromagnetic (or without permanent magnets) SYNCHRO-SYM effectively doubles the performance of the best materials, packaging techniques, winding techniques, and manufacturing techniques that all other electric machine manufacturers optimally design into the same century old electric machine componentized circuit and control architecture to enable their so-called electric machine invention or performance.


As the only practical brushless and symmetrically stable multiphase wound-rotor “synchronous” doubly-fed electric machines, which electric machine experts theoretically considered to be the ideal electric machine system, SYNCHRO-SYM has ample in-house study and prototyping (e.g., synchronous doubly fed) and legacy third-party study and manufacture (e.g., wound rotor induction doubly fed). In consideration, SYNCHRO-SYM is straight-forward ready with only routine engineering and manufacturing efforts for power scaling to any customer needs. A Simple or Detailed Concept of Operation (CONOPS) is available. 


Compared to all other electric motor or generator systems, including highly optimized systems, SYNCHRO-SYM is a patented electric machine integrated circuit and control architecture that provides...(READ MORE)
