Abstract: A sheet conveyance apparatus having a motor and a detector to detect a sheet conveyance abnormality. The motor includes a discriminator to determine whether motor rotation is abnormal, and a controller having a first mode to reduce a deviation between a determined motor rotation phase and an instructed phase, and a second mode to control a driving current based on a current having a previously determined magnitude. The controller switches from the second to the first mode if a motor rotor target speed value becomes larger than a predetermined value during the second mode after motor driving is started in the second mode. Where the motor was stopped due to the detector detecting a sheet conveyance abnormality and the discriminator determine that motor rotation is abnormal, the controller starts and maintains the motor driving in the second mode, even if the target speed value becomes larger than the predetermined value.
