The invention relates to electrical engineering, in particular to low-speed electric motors and rotary transformers. Known Autonomous power supply system (Patent RF №2152069, publ. 27.06.2000)containing n power sources, each of which is through the appropriate regulator connected to the output pins, and n control units, each of which is connected with the control input of the regulating authority of the regulator, and the entrance through the corresponding block summation connected to the sensor error, and the summation block is executed in the form of two summing amplifiers, the output of the first one is connected with the input of the second summing amplifier whose output is the output of the summation block, characterized in that the power sources used by the three species, of which m - solar cells, p - rechargeable batteries, k secondary power sources, the control unit is made in the form of pulse-width modulator, the first summing amplifier each block summation performed with l inputs, each of which is connected with the l-outputs of these sensors the error and the input of the second summing amplifier in each controller is additionally connected with the source of the corresponding reference voltage with the voltage values of solar U·mi/S rechargeable battery U·(k+1)/S, for secondary power sources - U·ki/S, where U is twice the amplitude of the sawtooth voltage, S is the gain of the second summing amplifier appropriate regulator, with m+p+k=n, and 2≤l≤n, mi=1,...,m; ki=1,..., k. The disadvantage of analog is the poor transfer of energy from solar panels on the spacecraft. Usually this question is solved by use of the brush-contact node (in case of rotation of SB relative to the SPACECRAFT) or a cable drum (in turn SAT on a limited angle). Known space solar power Glezer to provide electricity terrestrial consumers (as Gatland. Space technology. M.: Mir, 1986 s-237, Fig. on str). It consists of a large team of construction with a powerful solar power plant and a system for remote transmission of energy on Earth in the form of microwave or laser radiation. Also known spacecraft for remote energy transfer (Application for patent of the Russian Federation 94032672, IPC B64G 9/00)containing the carrier and set it to the power plant and system for remote transmission of energy, characterized in that the system for remote transmission of energy is placed at the center of mass of the spacecraft. The drawbacks is that the PD system of transmission of energy by means of microwave or laser radiation is small, the issue of electromagnetic compatibility of the transmission system with other systems KA is very complex. The most optimal method for contactless transmission of energy at small distances (less than a few millimeters) is inductive. An example of such device is a rotary transformer, where the value of the output voltage does not depend on the rotation angle. The closest in technical essence to the present technical solution (its prototype) is asynchronous dual-frequency electric machine (patent RF №2313886, IPC H02K 17/12, publ. 27.12.2007, bull. No. 36) with squirrel-cage rotor and the two combined in a common core of three-phase stator windings with numbers of pairs of poles p1and p2in which the induced EMF frequency f1and f2accordingly, having terminals for connection to external electrical circuits, including power consumers, while simultaneously winding with the number of pole pairs p2attached three-phase capacitor excitation, characterized in that it has an engine as a source of mechanical power, resulting in a rotation of the machine shaft, and an additional three-phase capacitor excitation, connected in parallel to the winding with the number of pole pairs p1. The disadvantage of the prototype is that it is machine p is OBRAZOVATEL frequency and is not intended to transmit energy through the non-magnetic gap from the stationary device for rotating. The technical task of the present invention is to enable transmission of electric power from a stationary source to a rotating receiver, for example from rotating relative to the spacecraft solar panels for space apparatus, and drive the rotating receiver. Solving the technical problem, obtain the technical result consists in the possibility of transmission from a stationary source to a rotating receiver, which is achieved due to the fact that in the known two-frequency electric car with two combined in a common core of three-phase stator windings with numbers of pairs of poles p1and p2having terminals for connection to external electrical circuits, according to the invention the rotor is placed at least one phase winding having terminals for connection to external electrical circuits, and the machine is equipped with inverter DC to AC and AC-to-DC and the inverter DC to AC attached to the terminals of the stator winding with the number of pole pairs p2and to the terminals of the rotor winding with the number of pole pairs p2attached the inverter AC voltage to DC. In addition, the rotor mo the et be the number of magnetized poles, equal to 2·p1. In addition, the rotor may have a number of unmagnetized protrusions equal to 2·p1. The proposed solution is illustrated by the drawings (figure 1, 2). Figure 1 shows the structure of two-frequency electric machine excited with permanent magnets of the magnet rotor. Figure 2 shows the design of two-frequency electric machine with salient-pole non-excited rotor. On the dual stator of an electric machine in General, the grooves are located (figure 1): winding 1 with the number of pole pairs p1and the coil 2 with the number of pole pairs p2mentioned windings have terminals 3 and 4 for connection to external electrical circuits. The rotor can be made in several versions - with excitation from permanent magnets [of the magnet 5 or neravnopolochny (not shown)] and 6 - how salient unexcited rotor. If the rotor 5 is excited field of the permanent magnets, the two-frequency electric machine operates as a synchronous magnetoelectric. If the rotor 6 is not excited, the two-frequency electric machine operates as a synchronous reactive. The number of pairs of poles of the rotor 5 or 6 is equal to p1. Also on the rotor 5 or 6 is the phase winding 7, having a terminal 8. In steady state excited rotor 5 or unexcited rotor 6 rotates synchronously with the field exchange rate is TCI 1 stator angular frequency Ω=2·π·f 1/p1. Thus, the winding 1 is required to drive the rotor 5 or 6 and rotation of the solar battery, which is connected with the rotor. The coil 2 placed in the slots of the stator, and the coil 7, is placed in the slots of the rotor act as a rotary transformer for transmitting energy through a non-magnetic gap, including from the stationary part to the rotating. The frequency f2>f1to increase the efficiency of energy transfer. To the winding with the number of pole pairs p2not created a field that can create spurious point in an electric car with an electromagnetic reduction of speed, it is necessary to fulfill the condition: k·p1≠p2where k is an integer. For contactless energy transfer requires the presence of AC voltage. The output voltage of the solar constant, energy storage on the SPACECRAFT are rechargeable batteries, which are also charged with a constant voltage. For providing contactless energy transfer constant voltage SB is converted to AC by inverter DC to AC (DC-AC Converter) with nodes "soft" switching on the AC side voltage, attached to terminals 4. Then there is the transfer of energy through the non-magnetic gap on the spacecraft group is the rotary coils 2 and 7. The energy required to charge the batteries, again converted into the energy of a constant voltage by means of an AC-to-DC (AC-DC Converter)attached to the terminals 8. For this system the energy transfer large capacity you can use a quasiresonant Converter with phase control, which over the classic Converter with pulse-width modulation has the following advantages: smaller size, higher efficiency, and lower levels of radiated noise. Thanks to the use of soft switching keys can provide the required level of reliability of the Converter. The technical result of the present invention is to increase reliability in comparison with the devices of the energy transfer from the brush-contact node, and the weight and improve performance compared to devices that transfer energy from the cable drum. 1.
