  • Motor control apparatus, motor control method, motor system, and computer-readable medium
    Patent number: 8957620
    Abstract: A motor control apparatus that controls the rotational angle of a motor (111) which drives a rotating body (112) includes a synchronizing means (200) for generating and outputting an interrupt signal (700) based on an external reference signal (600) input from outside and a rotating body reference signal (500) generated by the rotating body, and a controlling means (300) for computing a command value for making the rotational angle of the motor follow a target rotational angle and outputting the command value to the motor each time the interrupt signal is inputted. The synchronizing means (200) changes the output period of the interrupt signal (700) in accordance with a time difference between the external reference signal (600) and the rotating body reference signal (500).
