ABSTRACT:
A variable magnetic reluctance generator is disclosed generally comprising a stator having pairs of spaced magnetic poles of opposite polarity. Like polarity poles are adjacent one another to define a gap having all poles of the same polarity on the same side, and permanent magnet means provide an essentially uniform magnetic field intensity along the length of the gap. The opposite polarity poles are connected by a magnetically permeable path that is surrounded by a stator winding. The rotor has alternating segments of high and low magnetic permeability and these segments move through the gap between the opposite polarity poles, which changes the magnetic permeability between them. This causes variations in the magnetic flux in the magnetically permeable path, which induces an electrical current in the surrounding stator winding. Output voltage may be controlled by auxiliary field coils on the stator or by other means.
