- FIG. 1 there is shown a power supply system according to a general embodiment of the invention. It comprises a machine 100 composed of a rotor 110 and a stator 120.
- the rotor 110 is connected to a mechanical arrangement 130 for its drive by a rotor of a propulsion engine.
- the rotor coils are connected to an electrical connection 140 for the power supply of electrical equipment.
- the stator coils are connected to an electrical connection 150 for the application of electrical energy, including an alternative electrical energy.
- the asynchronous machine 100 has, over a predetermined range of drive speed by the rotor of the rotor propulsion motor of the asynchronous machine, a power transfer efficiency of the stator 120 to the preferred rotor 110 with respect to the conversion efficiency.
- mechanical energy rotation in electrical energy This is achieved by design: the transformer effect is optimized for a rotational speed range, to the detriment of the torque taken.
- the rotor 110 is for example three-phase balanced coil. To do this, the machine has the same number of pairs of poles in the stator and the rotor, or has a winding that can adapt to the balanced three-phase current.
- a possible design of the system of Figure 1 uses 6 pairs of poles and a gap of 1 mm.
- a stator voltage of 120 V RMS (relative to the neutral) is applied at 600 Hz, for a supplied electrical power of 24.7 kW, while the rotor of the asynchronous machine is driven at 15 Hz.
- the voltage obtained at the rotor then has a frequency of 690 Hz, an amplitude of 108 V RMS (relative to the neutral) for a power supplied 24 kW. It can be seen that a mechanical power of 3.3 kW is taken from the rotor and that the machine generates only 4 kW of losses, essentially related to the transformer function.
- the predetermined range of drive speed by the rotor of the rotor propulsion motor of the asynchronous machine, on which a power transfer efficiency of the stator 120 to the rotor 110 is preferred over the conversion efficiency of mechanical energy of rotation in electrical energy is a range around the frequency of rotation of 15 Hz, for example the range 10 to 20 Hz, or the range 14 to 16 Hz.
- the effect of optimization is illustrated by the low value of losses (4 kW), combined with a levy on the power released by the propulsion engine which, although far from being optimized, since it has on the contrary been neglected to allow the optimization of the transformer effect, is only 3.3 kW.
- the power supplied to the electrical connection 140 is regulated by adjusting the power applied by the electrical connection 150.
- the power level required for the stator can be, under certain conditions, lower than the output power at the rotor, thanks to the power provided by the propulsion engine.
