Abstract: Energy supplying system in which effective use of waste heat from a solar power generator and an engine power generator. Electric power generated by an SLCS (sunlight cogeneration system) 1 and an EGCS (engine cogeneration system) 2 is supplied to a power consuming apparatus while its relevant waste or exhausted heat is transferred to a heat consuming apparatus 3. The power generated by the SLCS 1 varies depending on the local climate and is monitored with a power meter 6 or a power monitor apparatus 7. When the power from the SLCS 1 is declined, it is compensated by increasing the power output of the EGCS 2. Since the total power generated by the SLCS 1 and the EGCS 2 is maintained constant and the total waste heat released from the SLCS1 and the EGCS 2 is relatively stable, the heat consuming apparatus 3 as well as an power consuming apparatus 5 are steadily energized.

Abstract: Proximity switches and circumferentially movable stator windings allow a motor-generator to simultaneously sense and switch from a synchronous motor position to a synchronous generator position. This mechanism replaces the conventional separate sensing and switching of motor-generator functions. Automatic rotational repositioning of the stator maintains constant voltage and prevents the generation of transient voltages or harmonics. The stator flux leads the rotor magnetic flux slightly in an import power or motor position, creating a torque on the rotor and a counter torque on the stator reacted by the fixed casing of the apparatus. As the stator field weakens due to a failure of the normal power supply, the counter torque also weakens and the stator windings are biased to begin to turn with the rotor until the rotor and stator fields are in step, i.e., when virtually no current is generated or consumed or until a full export power or generator position is reached.
