Dual armature single field DC motor/generator

A dual armature single field Direct Current (DC) motor/generator, comprising:

• a rotatable shaft maintained in a rotatable, axial position relative to a housing;
• an inner rotor armature secured to said rotatable shaft, wherein said inner rotor armature includes one or more inner rotor armature electromagnets;
• one or more field poles, each of said one or more field poles having a field pole electromagnet;
• one or more interpoles, each of said one or more interpoles having an interpole electromagnet, wherein said field poles and said interpoles are each secured to said housing;
• an inner rotor commutator assembly including an inner rotor commutator and one or more inner rotor brush leads, wherein each of said inner rotor armature electromagnets is in electrical contact with an appropriate segment of said inner rotor commutator, via said inner rotor commutator assembly, such that an electrical current may be selectively provided to said electrically conductive segments of said inner rotor commutator;
• an outer rotor armature secured to said rotatable shaft, wherein said outer rotor armature includes one or more outer rotor armature electromagnets;
