A machine has a housing (22) that includes a plurality of stator coils (30) to be positioned adjacent to a rotor (31). A switching network (28) includes a plurality of transistors (29) and diodes (131) connected to the coils (30). A current source inverter is provided by a switching network, a pair of inductors (26) positioned on power rails, and commutating capacitors (32). The current source inverter and the coils (30) are all positioned within said housing (22). Power architecture for a vehicle has a source of DC power, which communicates with machines through integrated motor drives. The motor drives include at least three coils positioned adjacent to the rotors for a motor associated with the integrated motor drive. A storage switching network is positioned downstream of the coils, with the storage switching network to be closed to allow power from the coils to drive the rotor, or to be opened to allow power to pass to a local storage component.
