Abstract
An apparatus including a stationary field coil wound with alternating insulated copper wire and insulated steel wire; a rotatable armature comprising a plurality of lengthwise rows of magnets, each row being of a single polarity which is opposite from the polarity of the next adjacent rows; a rotatable sleeve positioned between the field coil and the armature and spaced apart from each, the sleeve comprising a plurality of lengthwise strips of material that attract magnetic flux, spaced apart from each other by a strip of magnetic material that is transparent to magnetic flux, and means to rotate the armature or the sleeve while the other remains stationary.
Claims21
An electric generator including a stationary field coil, an armature rotatable within the field coil, and a warp sleeve rotatable between said coil and said armature;
- said coil comprising side-by-side alternating insulated lengths of wire, one insulated length consisting of copper wire and the other insulated length consisting of steel wire;
- said armature comprising a cylindrical core structure containing on its outside surface a plurality of spaced parallel lengthwise strips of magnetic material having one polarity alternating with a plurality of spaced parallel lengthwise strips of opposite polarity;
- said warp sleeve comprising a hollow cylinder positioned in close proximity to and spaced apart from the inner surface of said coil and the outer surface of said armature, said sleeve having over its entire length alternating lengthwise strips of material transparent to magnetic flux and material attractive to magnetic flux;
- and means to rotate one of said armature and said warp sleeve while maintaining the other stationary.
An electric generator comprising:
- (a) a stationary field coil having a central lengthwise cylindrical passageway and including at least three coils of wire electrically connected to each other through switches to provide selective parallel or series connections, each coil including windings of substantially equal lengths of insulated copper wire and insulated steel wire positioned such that contiguous lengthwise to substantially every portion of the copper wire winding is an equal portion of the steel wire winding;
- (b) a cylindrical rotatable armature located concentrically inside and spaced apart from said field coil, the outside surface of the armature being substantially covered with parallel lengthwise strips of magnets of substantially the same surface area and magnetic strength, each strip having one identical polarity over its entire outside surface and being positioned lengthwise between adjacent strips having the opposite polarity over their entire outside surfaces;
- (c) a warp sleeve comprising a selectively rotatable tubular structure mounted concentrically in the space between the field coil and the armature and spaced apart from each, the sleeve consisting essentially of alternating lengthwise strips of material transparent to magnetic flux positioned between alternating strips of material attractive to magnetic flux;
- and
- (d) means to rotate one of said armature and said sleeve about the lengthwise axis common to each while keeping the other stationary.
