設けて成るモータのドライブ回路。 A current in the first direction is caused to flow through the coil by intermittently turning on the second switch during the ON period of the first switch, and then intermittently turning on the fourth switch while the third switch is ON. By turning on the coil, a second direction opposite to the first direction is applied to the coil.
a first diode configured to flow a current in the direction, and for causing a current due to a back electromotive voltage generated in the coil to flow in the first direction due to the current in the first direction; and a second diode for causing a current due to a back electromotive force generated in the coil to flow in the second direction.
