Abstract

It relates to a method for increasing the electric power output by weakening the electromagnetic braking force to be exerted on a rotor of an electric generator. If secondary air gap besides the primary one is formed by "Gap core" or "Virtual air gap" in an armature magnetic circuit of the electric generator, the frequency of the electric generator is increased and the energy is conserved by weakening the electromagnetic braking force to be exerted on the rotor of the electric generator. A core between primary and secondary air gap is named "Gap core"."Virtual air gap" is the short and narrow part of a ferromagnetic core which is formed by grooving certain part of armature core or field pole. If "Virtual air gap" is saturated, it is characteristic of air gap and operates as secondary air gap. It is directed to produce electric power by consuming less energy.
