Abstract: An actuator includes a first stator with four first poles and a second stator with four second poles aligned with the four first poles. A permanent magnet is attached to the first stator and the second stator. Four moving armatures are positioned at terminal ends of the four first poles and the four second poles. Coils are wrapped around the first stator and the second stator. A controller selectively applies current to the coils to migrate flux created by the permanent magnet through selective poles of the first stator and the second stator and thereby alter the size of air gaps associated with the four moving armatures.

Abstract: The invention discloses a high speed switching solid state relay circuit with a switching section, a current limiting section and a voltage limiting section. The switching section comprises a bridge rectifier receiving the load voltage inputs, a MOSFET with a source connected to the negative voltage of the load through the bridge rectifier, a drain connected to the load voltage output, and a gate.

The current limiting section includes a first set of resistors connecting the voltage drop across the load to the gate of the MOSFET through diodes. The voltage limiting section comprises a Zener diode connected to the gate of the MOSFET.

Abstract: An electro-mechanical device that functions as a motor or a generator and methods for constructing and using such electro-mechanical device are provided. The electro-mechanical device features permanent magnets placed in a magnetically attracting manner and inter-dispersed between control coils. The control coils are energized to create a flux opposing the flux of the permanent magnets and to create a rotational torque on the poles of a salient pole rotor before those poles align with the poles of the energized control coil stator segment. Power can be generated by placing the flux of the control coils in a steady state and mechanically rotating the salient pole rotor. The electro-mechanical device provides little or no cogging forces, high-efficiency operation, and a high power density.
