Abstract
A sliding door driving device includes: a power source; a motor that outputs power to open and close the door; a motor driving circuit that connects the power source and the motor to each other; and a motor control device that controls the motor driving circuit. The motor control device includes an inverter that converts DC power supplied from the power source into AC power, and a shunt resistor disposed between the power source and the inverter. The position detection unit of the motor control device obtains the rotation angle of the motor based on the output of the shunt resistor.
