摘要： A motor driving apparatus that includes a current changing component, a detecting component, a control component, a back electromotive voltage zero cross detecting component, and a change control component. The current changing component drives a motor. The detecting component detects a point where a value of a magnitude of a current flowing into a coil of the motor changes from a decrease to an increase. The control component controls so that supply of the current to the coil is shut down, when the point is detected and the back electromotive voltage zero cross detecting component detects a zero cross of a back electromotive voltage generated in the coil. The change control component controls so that the direction of the current flowing into the coil changes to a reverse direction opposite to the predetermined direction, when the zero cross is detected.
