Abstract
A sheet conveyance apparatus includes a first conveyor, a second conveyor provided downstream of the first conveyor, a first motor configured to drive the first conveyor, a second motor configured to drive the second conveyor, a speed determining unit configured to determine a rotation speed of a rotor of the second motor, a command determining unit configured to determine a command speed representing a target speed of the rotor of the second motor, and a controller configured to control a drive current flowing through a winding of the second motor so that a deviation between the command speed determined by the command determining unit and the rotation speed determined by the speed determining unit is decreased. The command determining unit determines the command speed based on a value corresponding to a rotation speed of a rotor of the first motor.
