構成したことを特徴とするモータ制御回路。 One end of the motor is connected to the power supply positive line, and a first NPN transistor whose collector is connected to the other end of the motor via a detection resistor and whose emitter is grounded is provided. A first voltage dividing resistor for applying an operating voltage based on voltage is connected between the power supply positive line and ground, and a second NPN transistor whose collector and emitter are connected between the base of the first transistor and the ground is provided; A second voltage dividing resistor that applies a divided operating voltage to the base of the second transistor is connected between the connection point between the motor and the detection resistor and the ground via a switch that is temporarily opened only when the motor is started; When the motor starts, the first transistor is made conductive through the first voltage dividing resistor, and when the motor load increases, the divided voltage value increases by the second voltage dividing resistor, causing the second transistor to conduct and the first transistor to become non-conductive. A motor control circuit characterized in that it is configured as follows.
