Concentric motor power generation and drive system

An apparatus, comprising:

• a hub, including opposing faces, a first sidewall fixed to the opposing faces to define a first interior and a second sidewall fixed to one of the opposing faces to define a second interior within the first interior;
• a first assembly, disposed within the second interior, to generate current from input mechanical energy;
• a second assembly, electrically coupled to the first assembly and disposed within the first interior, to generate mechanical energy to be transmitted to external mechanical elements from current associated with the current generated by the first assembly;
• first and second couplings, the first coupling being disposed to mechanically couple the first and second assemblies and the second coupling being disposed to mechanically couple the second assembly and the external mechanical elements;
• and
• an energy capture circuit electrically interposed between the first and second assemblies to capture electrical energy from the generated current,
• wherein at least one or both of the first and second assemblies are configured to supply energy to the energy capture circuit with the second coupling disposed in an open condition.

An apparatus, comprising:

• a hub, including first and second opposing faces, a first sidewall fixed at opposite ends thereof to the first and second opposing faces to define a first interior between the first and second opposing faces and a second sidewall fixed to one of the first and second opposing faces to define a second interior within the first interior;
• a first assembly, disposed within the second interior, to generate current from input mechanical energy;
• a second assembly, electrically coupled to the first assembly and disposed within the first interior, to generate mechanical energy to be transmitted to external mechanical elements from current associated with the current generated by the first assembly;
• and
• first and second couplings, the first coupling being disposed to mechanically couple the first and second assemblies and the second coupling being disposed to mechanically couple the second assembly and the external mechanical elements such that the input mechanical energy is respectively transferable from the first assembly to the second assembly and from the second assembly to the external mechanical elements.
