Abstract: An axial field generator for use with the Sikes Windcrank™ vertical axis wind turbine is disclosed. One embodiment of the axial generator employs: 16 pairs of puck or disk shaped permanent magnets are provided radial and angular location by an index plate. and mounted on two opposing soft steel rotor plates by virtue of magnetic force. the magnets mounted with opposing fields that alternate in pole orientation: and a stator with 12 electronically commutated circular coils loaded with ferrite cores. The stator is a dielectric plate structure interposed between the opposing rotor plates. The stator coils may be switched to provide 4 poles in a three-phase AC configuration, up to 12 phase with single poles for each phase; or electronically rectified and commutated to provide DC voltage, that may be inverted into any useful wave form.

Abstract: Multiple, timed three-lobed rotor that are more efficient yet uncomplicated and easy to produce. A rotor lobe with additional reaction surfaces near the tip to increase the angle of rotation that produces power. A “flow through” rotor having end plates that facilitate mounting more than one rotor on a common axis with rotationally varied timing and sequence, such that power delivery is smooth. A flow shielding and directing device that increases the efficiency of reaction surface rotors. Possibilities include replacement or augmentation of: existing electrical energy prime mover dynamos, air compressing, pumping, milling, and other power needs. The dynamo can be built using low-tech, low-cost materials and methods, and is inherently resistant to over speed and damage from periodically high velocity fluid flow.

Abstract: Several synergistic improvements to a prime mover Dynamo including: A three-lobed rotor that is more efficient yet uncomplicated and easy to produce. A rotor lobe with additional reaction surfaces near the tip to increase the angle of rotation that produces power. A “flow through” rotor having end plates that facilitate mounting more than one rotor on a common axis with rotationally varied timing and sequence, such that power delivery is smooth. A flow shielding and directing device that increases the efficiency of reaction surface rotors mounted on a common axis by blocking flow to the back side of reaction surfaces, and extracting stagnant fluid through vanes that are energized by redirected free stream fluid flow, whereby increased torque and smother operation are evident verses typical prime mover dynamos.
