ABSTRACT:
A motor control system for a fuel burner comprises a microprocessor and a voltage fluctuation compensating portion provided with a bridge circuit for rectifying the current of a power source, a portion for generating a comparison signal having a delay time corresponding to the voltage fluctuation of the rectified signal from the bridge circuit and a portion for generating a zero-crossing signal from the voltage signal of the bridge circuit, whereby a microprocessor determines whether a power voltage applied to the system is higher or lower than a normal voltage. The microprocessor generates a compensating signal programmed to equalize the fluctuation power to the reference power and a controller controls the power to be applied to a load according to the compensating signal.
