動制御回路である。By the way, since the above circuit uses a certain standard type soil, voltage comparison is performed once per cycle of frequency power generation (ac output), but in the present invention, this reference voltage is changed every half cycle. The purpose of this is to improve the speed control by eliminating the need to compare the voltage twice per cycle and to achieve more fine-grained speed control. The capacitor charged by the current source is discharged at the rising edge of the rectangular wave obtained by rectifying the alternating current output of the frequency generator until the capacitor is discharged at the rising edge of the next period of the rectangular wave. In the circuit that charges the current source to generate a triangular wave, compares the triangular wave with a reference voltage, and supplies current to the motor when the wave height is at a phase angle exceeding the reference voltage. This motor drive control circuit is characterized in that voltage comparison is performed twice within one cycle by switching the voltage value every half cycle of the phase angle of the rectangular wave.
