  • Publication number: 20170187321
    Abstract: A motor control device includes a controller and a detector. The controller is configured to control, when receiving an operation request indicating rotation or stop of a motor, rotation of the motor based on the operation request. The detector is configured to detect whether the motor is rotating. The controller stops the motor when the detector detects rotation of the motor after an elapsed time from reception of the operation request indicating stop of the motor reaches a first threshold.
