Abstract:
To provide a current motor control device and method that can check the rotation frequency and direction of a direct current motor without wearing a brush or commutator.
The direct current motor control device and the method are disclosed. The direct current motor control device includes a direct current motor driver that impresses a drive voltage to the direct current motor for detecting a predetermined signal from the direct current motor and a servo microcomputer that uses a signal detected from the direct current motor driver for controlling the direct current motor.
