Abstract
A motor-related information processing circuit includes acquisition circuitry, first writing circuitry, and second writing circuitry. The acquisition circuitry acquires motor-related information regarding an operational state of a motor when the motor is driven. The first writing circuitry writes the motor-related information to a volatile memory after the motor-related information is acquired. The second writing circuitry writes the motor-related information stored in the volatile memory to a non-volatile memory when driving of the motor is stopped.
