Cómo conectaste ese avr, tengo uno igual y lo pruebo con un generador de 13kw y no me funciona

Akbar - generally, unstable frequency is due to the prime mover [engine] unable to produce full torque at steady rpm usually 1500 [50hz] or 1800 [60hz] , check #1 fuel filter flow is good and fuel is new and clean change filter if not or service fuel pump if delivery pressure is not maintained per engine service manual 2, check air filter is clean, change filter if not. without fuel + air engine will not produce steady rotation rpm. 95 percent of frequency problems are engine related 3- can be AVR automatic voltage regulator board which provides excitation magnetic field, but this is not likely on modern generators and last 4- your load may be highly dynamic with sudden large changes causing engine rpm to drop, for example starting air conditioner compressor. AVR should handle these sudden loads.

Sir you not mention if how the rotation if you going to increase or decrease the voltage thanks. in advance

@@verhillovalakay5393 rotation = frequency, always. constant rotation is the engine responsibility. Voltage is regulated with a control loop circuit board, usually called AVL. this circuit monitors the ac generator output voltage THEN it outputs a DC voltage, usually 30-90 VDC that drives exciter coil windings on the stator for a steady magnetic field. there are matching coils on the rotor that receive this magnetic field, then produce AC voltage that is rectified by usually 6 diodes also on the rotor to a DC voltage which runs the primary field coil winding also on the rotor to simulate a spinning magnet. more output from the AVL gives you higher voltage from the generator because the magnetic field gets stronger on the rotor. note this is for large, 10kva+ 3 phase diesel generators - small 5kva gasoline generators work differently and should be avoided as they will damage sensitive electronics.
