Abstract
A driving device for driving a first motor to transmit a driving force to a driven object and a second motor to transmit a driving force to the driven object include a controller and a corrector. The controller outputs a first voltage command value to drive the first motor and a second voltage command value to drive the second motor. The corrector corrects the first voltage command value and the second voltage command value, based on a parameter relating to driving of the first motor and the second motor obtained when an output torque of the first motor and an output torque of the second motor are applied to the driven object in opposite directions.
