Abstract:
1. A method for manufacturing a micro gas turbine for generating electrical power, the method comprising the steps of: (a) acquiring an existing compressor-turbine unit; (b) disassembling the existing compressor-turbine unit into a compressor having a compressor shaft, and a turbine having a turbine shaft; (c) extending either, or both, of the compressor shaft and the turbine shaft; (d) joining the compressor shaft and the turbine shaft together to form a common shaft; (e) providing two bearing units; (f) connecting one of the bearing units to the compressor and the other of the bearing units to the turbine; (g) manufacturing a generator housing with interfaces for connection with the two bearing units or other stationary parts; (h) acquiring an existing generator; (i) disassembling the existing generator to remove a stator and a rotor; (j) mounting the stator of the existing generator in the generator housing; (k) mounting the rotor of the existing generator on the common shaft, such that the combination of the compressor, the turbine, the common shaft, the stator, and the rotor, are suitable for generating power in the typical power range of 1 kW to 5 kW; and (1) connecting the generator housing with the two bearing units or other stationary parts.
