電動機の駆動装置。In a device that drives a DC motor by converting AC power output from a synchronous generator into DC using a rectifier and supplying the obtained DC power to a DC motor, DC excitation is applied to the field winding of the synchronous generator. A residual magnetic flux elimination device that supplies alternating current to the field winding is provided in parallel with the excitation device that supplies current, and in response to a stop command of the DC motor, the DC excitation current that is supplied from the excitation device to the field winding is A driving device for a DC motor, characterized in that upon narrowing down, the residual magnetic flux canceling device starts supplying alternating current to the field winding, and gradually reduces this alternating current over time.
