FIELD: electricity.

SUBSTANCE: stabilised radial-axial contactless electric generator comprises a housing. In the lower part of the housing there is a constant-voltage regulator comprising a power supply unit for the connection to the battery, a reactor, a comparator, a saw-toothed wave former, whose output is connected to an inverting input of the comparator, a control signal former, whose output is connected to a non-inverting input of the comparator, a field-effect transistor, whose base is connected to the output of the comparator, and an emitter is connected to the positive output of a multiphase full-wave rectifier. The collector of the field-effect transistor is connected to the first terminal of the reactor, to the second terminal of which a smoothing capacitor is connected. The comparator is executed on the first operational amplifier. The saw-toothed wave former comprises a square-wave generator consisting of the second operational amplifier, the first positive feedback resistor connected to the output and non-inverting input of the second operational amplifier. A saw-toothed wave generator consists of the third operational amplifier, the second positive feedback resistor connected to the output of the third operational amplifier and non-inverting input of the second operational amplifier, integrating capacitor of negative feedback connected to the output and inverting input of the third operational amplifier. A voltage divider connected to the power supply unit consists of the first and second resistors, whose output is connected to the inverting input of the second operational amplifier and non-inverting input of the third operational amplifier. The resistor is connected to the output of the second operational amplifier and the inverting input of the third operational amplifier. The generator control signal former comprises the fourth operational amplifier, an adjustable resistor connected to the power supply unit, the first voltage-dropping resistor connected to the positive output of the rectifier and inverting input the fourth operational amplifier. The second voltage-dropping resistor is connected to the adjustable resistor and non-inverting input of the fourth operational amplifier. The negative feedback resistor is connected to the output and inverting input of the fourth operational amplifier. A bias resistor is connected to the non-inverting input of the fourth operational amplifier, which determines the magnitude of the voltage bias at the non-inverting input of the fourth operational amplifier.
