徴とする送風機モータの回転制御装置。 A rotation control device for a blower motor in which the rotation of the blower motor is controlled by a resistor provided in a drive circuit of the blower motor, wherein the blower motor is in a maximum rotation mode in which current is supplied to the blower motor without passing through the resistor. A resistor that generates heat and melts due to the current flowing when an abnormality occurs in the blower motor even when the power supply voltage is at the lower limit value is interposed in series between the blower motor and the resistor. Rotation control device for blower motor.
