Abstract
This Invention relates to an efficient method of generating electrical power. The invention provides a method of limiting or reducing the cannier electromagnetic field generated between the staler and rotor of a generator or alternator. The- method includes using multiple closed magnetic loops, each closed magnetic loop created around an induction coil, thereby trapping most or all of the counter electromagnetic field generated in the induction coil (is accordance with Lenze's Law) during normal use. The invention extends to a generator with two separate stators and a common rotor. The invention also includes a method of extracting heat from an induction coil in an enclosed system. Several embodiments are disclosed. In one embodiment the system is organized to generate a DC voltage, thereby limiting or reducing losses. Embodiments organized to generate AG voltages are also disclosed.
