ラシレスモータ回転数制御回路。 A transistor is connected in series to each phase winding of a two-phase brushless motor, and a diode and a variable resistor or a temperature-dependent resistor connected in series to the diode and used in common are connected between the collector of each transistor and a power supply. . A DC brushless motor rotation speed control circuit, which controls the conductivity of the transistor by changing the resistance value of the variable resistor or the temperature-dependent resistor, thereby making it possible to vary the rotation speed.
