DC electric motor control device

A DC electric motor control device comprising:

• 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 and 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,
• wherein, when performing the normal rotation control of the DC electric motor, the controller initially performs reverse rotation control of the DC electric motor for a predetermined time using the motor driving circuit, 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, and
• wherein, when performing the reverse rotation control of the DC electric motor, the controller initially performs the normal rotation control of the DC electric motor for a predetermined time using the motor driving circuit and the controller performs the reverse rotation control only when the abnormality determination part determines that the abnormality is not generated during the normal rotation control.
