It is an idea to avoid problems with voltage stability in a cheap two-stroke aggregate using Fiat 126p. In this type of generator of the aggregates there is a lot of space. That is why it was possible to place there slip rings from the car alternator and a brush plate. On the rotor there are two aluminum windings, about 9ohm each. They were connected in series and their ends were connected to the slip rings. The rings were drilled from the inside to the diameter of the shaft and pasted by poxilin.
In a stator of such an aggregate, there are two windings. One of them is a working winding, on which while operating there is about 230V, the second is excitation, which is originally connected to a capacitor (about 100V) and another winding to power the rectifier, on which the voltage is 17V when 230V is on the main rectifier. The winding to power the rectifier is tapped from the working winding. After the measurements, it turned out that AVR controller will fit the aggregate. These are the controllers for the larger aggregates 2kW to 4kW.
The auxiliary winding (about 100V, instead of a capacitor) was connected to the yellow wires. The winding that powers the rectifier, also called measurement (about 17V) was connected to the blue and brown wire. The other two wires were connected to the rotor brushes. Voltage ranges may be about 5V when connecting once 50% load about 450V.
