Abstract
A DC electric motor control device has a motor driving circuit that is constructed by a plurality of switching elements, a controller that operates the motor driving circuit to control a normal rotation or a reverse rotation of a DC electric motor, and an abnormality determination part that determines whether an abnormality is generated while the controller controls the DC electric motor. The controller previously performs reverse rotation control of the DC electric motor for a predetermined time using the motor driving circuit when performing normal rotation control of the DC electric motor, and the controller performs the normal rotation control only when the abnormality determination part determines that the abnormality is not generated during the reverse rotation control.
