Publication number: 20190115856Abstract: A motor control system is used to detect a failure of an encoder without the arrangement of a dedicated sensor. The motor control system includes an electric motor, a position detection unit that detects a rotational angle position (n) of the electric motor. A current control unit that controls a current value (I) is supplied to the electric motor. A current detection unit detects the current value (I) supplied to the electric motor. A current fluctuation determination unit determines whether or not there is a change in the detected current value (I), a position fluctuation determination unit that determines whether or not there is a change in the detected rotational angle position(n), and a failure determination unit that determines that there is a failure in the position detection unit if the current value (I) is changed and the rotational angle position (n) is remained unchanged.Type: ApplicationFiled: December 11, 2018Publication date: April 18, 2019Applicant: Olympus CorporationInventor: Kyohei Kurihara
