PROBLEM TO BE SOLVED: To provide an actuator system wherein torque value detection accuracy is enhanced even when an motor is in operation.SOLUTION: The actuator system includes a controller 54 that calculates a torque value from a detection value detected by a magnetostrictive torque sensor 80, a brushless motor 50 that drives according to the torque value calculated by the controller 54, and a magnetic pole sensor that detects the rotation angle of the brushless motor 50. The controller 54 detects the timing of switching of the poles of the permanent magnets 64 of the brushless motor 50 or the magnets 86 of the magnetic pole sensor based on the result of detection by the magnetic pole sensor. The controller does not use the detection value detected by the magnetostrictive torque sensor 80 in the calculation of the torque value with the detected timing of switching. |
