Abstract
A motor control system includes a motor and a motor control circuitry. The motor includes a rotation axis and a bearing rotatably supporting the rotation axis. The motor control circuitry is configured to control the motor. The motor control circuitry includes a driving time adding circuit configured to add up a driving time of the motor to obtain an accumulated driving time of the motor, a remaining lifetime calculation circuit configured to calculate a remaining lifetime of the bearing based on a lifetime of the bearing and the accumulated driving time, and a warning outputting circuit configured to output warning information when the remaining lifetime is equal to or less than a threshold.
