Abstract
An electromagnetic coupler comprises an electric generator consisting of a housing, an end cap, a rotor, and a stator constituted by an induced unit, and a transformer consisting of an induction primary winding and a secondary winding of the induced unit. A winding (2) of the induced unit is induced by transformed magnetic lines of force to produce an electric current. Induction magnetic lines of force produced by the electric current are enclosed in the induced unit, forming a closed loop of magnetic lines of force. An induction magnetic field departs from a magnetic source, passes through a magnetic permeability neck (12), and returns into the induction magnetic field, forming the closed loop of the magnetic lines of force of the induction magnetic field. Implemented in the electric generator and the transformer is that the induction magnetic lines of force and induced magnetic lines of force follow respective magnetic circuits of selves. The electromagnetic coupler converts electric energy at great efficiency.
