The spatial displacement of the coil groups of 60° and the phase shift of the currents in them excitation at 60° promotes the formation of six-phase two-pole stator winding of the brushless Autonomous asynchronous generator.

According to figure 3 option scheme include capacitors excitation scheme is six-phase star. Conclusions 8, 10, 12 connected first three-phase rectifier bridge 13 with the release of 15 DC "plus" and "minus"to conclusions 7, 9, 11 connected second three-phase rectifier bridge 14 out 15 DC "plus" and "minus"to conclusions 7, 8, 9, 10, 11, 12 connected capacitors excitation 16, 17, 18, 19, 20, 21 for valve Autonomous induction generator as an auxiliary power plant.

The geometric sum of the three phase Toko is presented in the form of the resulting vectors in the figure 4 and the vector diagram of EMF. Currents displaced in phase by 60°.

When working valve Autonomous asynchronous generator in the Autonomous power plant, for example, with capacitors connected in the circuit in figure 3, between pins 7, 9, 11 the magnitude of the EMF is the same as between pins 8, 10, 12. If we assume that between these findings EMF is, for example, 400 V, then for each given three conclusions can be connected three-phase load such as an induction motor of a certain power.

To each pair conclusions 7-8, 8-9, 9-10, 10-11, 11-12, 12-7 with a value of EMF 400/1,73 can be connected In single-phase load. Certain single-phase load can be connected to each pair of conclusions 7-10, 8-11, 9-12, between which the EMF is 466 Century

For example, in wind power plants during operation of a valve Autonomous induction generator for charging the battery 15 conclusions virtually eliminated the manifestation of the ripple of the rectified current. Conclusions 7, 8, 9, 10, 11, 12 allow you to connect and six-phase rectifier bridge.

Thus, when working valve Autonomous asynchronous generator in the Autonomous power it allows you to connect the load to different AC voltage, and together with the six-phase rectifier bridge or two three-phase rectifier bridges to supply the load with a constant current.

Ve is a stylish Autonomous induction generator with capacitor excitation and the stator winding of the six coil groups, having outputs, wherein the first output winding is taken from the joint end of the sixth and beginning of the first coil group, the second output is taken from the joint end of the first and beginning of the second reel group, the third output is taken from the joint end of the second and beginning of the third coil groups, the fourth output is taken from the joint end of the third and the fourth coil group, the fifth output is taken from the joint end of the fourth and beginning of the fifth coil groups, the sixth output is taken from the joint end of the fifth and early sixth coil groups to these conclusions winding attached to three or six excitation capacitors, the first and second three phase rectifier bridges, and the AC load connected to these pins in accordance with the desired load voltage and number of phases.
