Patent ID: 8649676

Claim:
A motor control device for controlling rotation of a DC motor for driving an object, comprising: a counter configured to count a pulse output from a one-phase encoder according to rotation of the DC motor; and a controller configured to recognize a rotation number of the DC motor based on the number of pulses counted by the counter, wherein after the DC motor which is being driven is braked, the controller starts applying a predetermined voltage to the DC motor at a first timing which is a timing before the DC motor stops, and stops the applying of the predetermined voltage at a second timing which is a timing after the DC motor stops, the controller subtracts the number of pulses generated after the second timing from a value counted by the counter, and the predetermined voltage is lower than a lowest voltage necessary for driving the object to be driven and higher than a lowest voltage necessary for rotating the DC motor against an attracting force between a magnet and a coil in the DC motor.
