とする車両用ブロアモータの速度制御装置。 In a blower motor speed control device that adjusts the air volume by steplessly changing the terminal voltage of a blower motor for a vehicle such as an air conditioning system, there is a voltage dividing resistor R1 between the base of the emitter floor circuit that connects the blower motor to the emitter of a transistor and GND. , R2
is connected to the voltage comparator to compare the voltage at the branch point of the voltage dividing resistors R 1 and R 2 with the air volume setting voltage. A speed control device for a vehicle blower motor, characterized in that a control current is supplied to the base of the vehicle blower motor.
