ABSTRACT:
A motor driving circuit includes at least one set of switching elements, each set of switching elements being two switching elements connected in series to each other, and a diode connected in parallel with one of the two switching elements connected on a power source side, a terminal of a motor to be driven being connected to a junction point between the two switching elements. A voltage transfer element is provided for transferring, from the junction point between the two switching elements, a voltage of a counter electromotive force generated at the motor, to an input end of the other of the two switching elements connected on a ground side.
