FIELD: electricity.
SUBSTANCE: device of automatic control of a power generator comprises a ferromagnetic ring, a part of which is placed into a saturating magnetic field of a strong permanent magnet, equipped with a magnetisation coil, and its other part is connected to a heat-releasing medium, for instance, purified water taken from the appropriate water pool, a three-phase AC generator connected to a three-phase rectifier and to an electric load, a control unit of the magnetisation coil of the strong permanent magnet, a reference voltage generator, a phase-sensitive rectifier and a low-pass filter (or an integrator), a a tacho-generator connected to each other as specified in the invention claims. The magnetic gap of the strong permanent magnet is made of two parts, the first of which forms a uniform magnetic field with intensity providing for maximisation of magnetic response of the ferromagnetic at the length L of this part of the magnetic gap, and the second part of the magnetic gap with the length L generates a saturating magnetic field in the beginning of this part of the magnetic gap and further a magnetic field in direction of movement of the ferromagnetic ring that linearly increases by intensity to the end of the magnetic gap. Angular speed ω* of the ferromagnetic ring rotation corresponding to the maximum value of the rotation torque that occurs in it is determined by the condition ω*=L/λRτ, where λ=1.23 and R - average radius of the ferromagnetic ring, τ - time constant of magnetic viscosity relaxation of the ferromagnetic, from which the ferromagnetic ring is made. The device that does not consume deficit fuel is an environmentally pure power engineering facility, which does not increase a thermal component during its operation, operates successfully in winter time, slightly decreasing its capacity.
EFFECT: improved power efficiency of a thermomagnetic converter of thermal energy of environment into mechanical work.
