Title: DC motor control device and control method

Abstract: A DC motor control device and a DC motor control method are configured to calculate driving motion time and DC motor current flow per unit time, or DC motor total current flow and driving motion time, every continuous driving motion of the DC motor, and interpose a drive stopping time to stop the DC motor for a time corresponding to the calculated value every time before a subsequent driving motion starts. Alternatively, they are configured to interpose a drive stopping time to stop the DC motor for a time calculated by cumulating such time corresponding to the calculated value over a plurality of occurrences every time before a subsequent block of driving motions starts after each block of driving motions.
