Abstract

A plurality of stator core rings are produced, each having circumferentially spaced pole teeth arranged symmetrically to a diametral plane. Certain of the rings are wound with two like sets of windings of wire of one gage, each set confined to its own side of said plane. The remaining rings are similarly wound, but with wire of a different gage. Every ring is then severed on its said diametral plane, thus forming stator elements of two kinds that can be assembled to engines singly or in pairs, as needed.

Claims

exact text as granted — not AI-modified
The invention is defined by the following claims: 
     
       1. The method of mass producing alternator stators intended to be installed on small engines for cooperation with permanent magnets carried by their flywheels, to enable certain of such engines to be equipped with a type of alternating current source suitable for powering load circuits such as headlights, others to be equipped with a type of alternating current source suitable, when rectified, for unregulated battery charging, and still others to be equipped with both types of alternating current sources, said method being characterized by: A. manufacturing a plurality of identical substantially annular stator core rings, each having an even number of circumferentially spaced pole teeth and being symmetrical to a diametral line;   B. winding on the pole teeth of each of a certain number of said rings two sets of windings of wire of one gage, said sets of windings being at opposite sides of said diametral line, each being wholly at its side of said line, and the two sets being identical to one another;   C. similarly winding on each of the remainder of said rings two identical sets of windings of wire of another gage; and   D. cutting all of said stator rings in half on said diametral line.   
     
     
       2. The method of mass producing alternator stators for small engines for cooperation with permanent magnets carried by their flywheels and each of which stators comprises an annular core having a plurality of circumferentially spaced pole teeth, a set of windings of a first type, wound around pole teeth at one side of the core and adapted to have induced in it a current suitable for energizing an a.c. load such as a light circuit, and a set of windings of a second type, wound around pole teeth at the diametrically opposite side of the core and adapted to have induced in it a current which, when rectified, is suitable for unregulated battery charging, said method being characterized by: A. winding on each of a first plurality of annular core rings two sets of windings of said first type, at diametrically opposite sides of the ring, each set of windings being confined to its own side of the ring;   B. similarly winding on each of a second plurality of annular core rings two sets of windings of said second type;   C. cutting all of said annular core rings in half, each on a diametral line lying between the sets of windings thereon, so that each half of a core ring contains a complete set of windings; and   D. assembling to each engine one wound ring half of said first plurality and one wound ring half of said second plurality. .Iadd. 3. The method of mass producing alternator stators intended to be installed on small engines for cooperation with permanent magnets carried by their flywheels, to enable certain of such engines to be equipped with a type of alternating current source suitable for powering load circuits such as headlights, others to be equipped with a type of alternating current source suitable, when rectified, for unregulated battery charging, and still others to be equipped with both types of alternating current sources, said method being characterized by:   A. producing a plurality of identical substantially annular stator core rings, each having an even number of circumferentially spaced pole teeth and being symmetrical to a diametral line so as to be separable on said line to provide a pair of identical half rings;   B. winding on the pole teeth of each of a certain number of said rings two identical sets of windings of wire of one gage, said sets of windings being at opposite sides of said diametral line and each being wholly at its side of said line so that the half rings into which each of said certain rings can be separated on said line ar identically wound;   C. similarly winding on each of the remainder of said rings two identical sets of windings of wire of another gage; and   D. after winding, separating all of said rings, each on its said diametral line, into wound half rings. .Iaddend. .Iadd. 4. The method of mass producing alternator stators for small engines for cooperation with permanent magnets carried by their flywheels and each of which stators comprises an annular core having a plurality of circumferentially spaced pole teeth, a set of windings of a first type, wound around pole teeth at one side of the core and adapted to have induced in it a current suitable for energizing an a.c. load such as a light circuit, and a set of windings of a second type, wound around pole teeth at the diametrically opposite side of the core and adapted to have induced in it a current which, when rectified, is suitable for unregulated battery charging, said method being characterized by:   A. winding on each of a first plurality of annular core rings two sets of windings of said first type, at diametrically opposite sides of the ring, each set of windings being confined to its own side of the ring so that each of said first plurality of rings is separable on a diametral line lying between the two sets of windings thereon into two identical wound half rings;   B. similarly winding on a second plurality of annular core rings two sets of windings of said second type;   C. separating all of said wound core rings, each on its said diametral line, into wound half rings, each of which comprises a complete set of windings; and   D. assembling to each engine one wound half ring of said first plurality and one wound half ring of said second plurality. .Iaddend.
