Switched reluctance motor manufacture with variable wire twist rate

A method of making an assembly for an electric motor, the method comprising:

• forming an electromagnetic coil by winding at least two electrically conductive wires into multiple wire turns that are wound lateral to a coil center, wherein the coil has a first side, a second side, a coil axis orthogonal to the coil center, and multiple wire turns per length of the coil axis;
• individually twisting the wires of wire turns of the coil located closer to the first side of the coil to include at least one-half twist per wire turn in each wire and not twisting the wires of wire turns of the coil located closer to the second side of the coil, and decreasing the number of twisted wire turns per length of the coil axis from the second side to the first side;
• forming a plurality of the electromagnetic coils;
• and
• disposing each coil of the plurality of coils onto a stator pole of a stator having multiple stator poles, each stator pole having a rotor end and a base end, and each coil disposed to have the first side of the coil closer to the rotor end of the stator pole and the second side of the coil closer to the base end of the stator pole.

An electric motor of a work machine, the electric motor comprising:

• a stator including a plurality of stator poles and a plurality of stator slots, each stator pole including a base end and a rotor end opposite the base end and each stator slot positioned between two stator poles;
• a rotor positioned with in the stator and including a plurality of rotor poles extending toward the stator poles;
• and
• a plurality of electromagnetic coils, each coil arranged around a stator pole and including:
• at least two electrically conductive wires wound into multiple wire turns of a coil arranged around the stator pole that extend from the base end of the stator pole to the rotor end of the stator pole, wherein the multiple wire turns of the coil include wire turns closer to the rotor end of the stator pole with wires that are each individually twisted to include at least one half twist per wire turn of the wire, and wires of wire turns closer to the base end of the stator pole are not twisted, and wherein the coil includes multiple twisted wire turns per length of the stator and the number of twisted wire turns per length decreases along the stator length from the base end of the stator pole to the rotor end of the stator pole to taper the number of twisted wire turns at the rotor end.
