摘要： A rotating electric machine according to the embodiments includes a rotating-electric-machine unit, a rotation detector, an Oldham coupling, and a washer. The rotating-electric-machine unit includes a shaft. The rotation detector includes a body and a rotation input pin that is rotatably provided on the body. The Oldham coupling couples the rotation input pin of the rotation detector and the shaft to each other while allowing any relative displacement in a direction intersecting an axial direction. The washer is provided on the rotating-electric-machine unit while being positioned with respect to the shaft. The washer includes an attaching portion at which the body of the rotation detector is attached to the washer.

摘要： A motor control system includes a motor, an encoder, and a controller including a controller transmitter configured to transmit a torque command to control the motor. The encoder includes a position detector configured to detect a rotational position of the motor, an encoder receiver configured to receive the torque command from the controller transmitter, first disturbance estimating circuitry configured to estimate a first disturbance torque based on the rotational position and the torque command, and an encoder transmitter configured to transmit the rotational position and the first disturbance torque to the controller.
