Claim 0:
1. A micro turbine assembly comprising:
a micro turbine engine subassembly, including:
a preassembled engine shaft assembly comprising:
elements of the preassembled engine shaft assembly onto an engine shaft, the elements being arranged from a first airflow discharge end of the engine shaft to a second, opposite end of the engine shaft in the following order: a turbine, a gap between the turbine and a compressor, a magnetic rotor and a thrust bearing,
a pair of semi-circularly shaped turbine spacers assembled to one another circumscribing and extending radially into the gap between the turbine and the compressor,
a compressor shroud in radial alignment with and circumscribing the compressor,
a stator portion of an electric generator positioned in radial alignment with and circumscribing the magnetic rotor,
a combustor, and
a heat sink;

a micro turbine air sourcing housing subassembly, including:
an engine housing and at least one of a turbine air intake scroll, and a compressor exhaust scroll, the engine housing having an interior surface defining an interior having an interior diameter; and

an air supply and electronics subassembly, including:
an air supply housing,
an air inlet at an upstream location of the air supply housing,
a digital signal processor assembled to the air supply housing,
a planar transformer assembled to the air supply housing, and
a multilevel inverter assembled to the air supply housing;

wherein the micro turbine engine subassembly is designed as a compact subassembly having a diameter and shape that is smaller than the interior diameter defined by the interior surface of the engine housing,
wherein the micro turbine engine subassembly is slideably inserted into the interior of the engine housing,
wherein the heat sink is located radially between the engine housing and the stator portion of the electric generator,
wherein the air supply and electronics subassembly is assembled to the engine housing forming the micro turbine assembly,
wherein a compressor air supply passes through the air inlet, the heat sink for cooling the electronics and the electric generator, and flowing into an intake of the compressor in that sequential order.
