Abstract: A door opening/closing device includes: a motor; and a control unit that is configured to control a rotation rate of the motor by pulse-width modulation (PWM) control. The door opening/closing device opens and closes a door of a vehicle with power of the motor. The control unit is configured to perform the PWM control on the motor at a PWM frequency set so as to deviate from a resonance point of an installation body on which the motor is installed.

Abstract: A door opening and closing device includes a motor that outputs driving force causing a back door of a vehicle to be opened or closed, and a controller that controls the motor. The controller executes automatic opening and closing control for automatically opening or closing the back door by the motor, and if the controller detects a stop command causing the back door to be stopped when the automatic opening and closing control is being executed, the controller decreases a target velocity of the back door at a predetermined deceleration α1 until the back door stops.
