AI Technical Summary
Technical Problem
Existing actuator systems require a complex configuration with external processing devices for abnormality detection, complicating the system setup.
Method used
An actuator system that integrates a motor with a first angle detection unit, a drive unit, a position sensor, and a determination unit to detect abnormalities based on the difference between estimated and measured positions, allowing for internal abnormality detection without additional external components.
Benefits of technology
Abnormality detection is performed without complicating the system configuration, enabling quick identification and shutdown of the actuator system when abnormalities occur.

Abstract
To provide an actuator system enabling detection of abnormality without complexing structure for detecting the abnormality.SOLUTION: An actuator system comprises: a motor having a rotating rotation shaft; a first angle detection part detecting a rotation angle of the motor; a drive part driving the motor on the basis of the rotation angle detected by the first angle detection part; an actuator driving an output shaft depending on rotation of the rotation shaft of the motor; a position sensor detecting the position of the output shaft of the actuator; and a determination part determining the occurrence of abnormality when difference between the position of the output shaft estimated on the basis of the rotation angle detected by the first angle detection part and the position of the output shaft detected by the position sensor is equal to or larger than a predetermined threshold.SELECTED DRAWING: Figure 1
