Zusammenfassung:	The system for controlling the motor speed variablly comprises a divider (12) dividing the reference frequency of a generator (11) with outer dividing control signal, a PLL controller (14) comparing the phases of the divided frequency (f1) and the rotation frequency (FG) of a generator (19) generating the real rotation frequency, a frequency/voltage converter (13), and a gain setting circuit (15) setting the gain by adjusting the output region of the PLL controller within the lock region.
