とを特徴とする直流モータの制御装置。[Claims for Utility Model Registration] Detecting means for detecting the value of current flowing through a DC motor, a first current target value set in advance, and a second current set in advance to a value smaller than the first target current value. The target value is compared with the output value of the detection means, and when the DC motor is started, voltage is continued to be applied to the DC motor until the output value reaches the first current target value from 0, and thereafter,
The application of the voltage is stopped from the time when the output value reaches the first current target value until it decreases to the second current target value, and when the output value reaches the second current target value, the application of the DC current is stopped. a control means that repeats control to start applying the voltage to the motor and continue to apply the voltage to the DC motor until the voltage reaches the first target current value, and the first current target value and the second current A direct current characterized in that the first current target value and the second current target value are set such that the frequency formed by the output value that fluctuates up and down between the target value and the target value is above the human audible range. Motor control device.
