<p>In order to control the stoppage, acceleration, deceleration, reverse rotation, etc., of a motor (1) based on the signal obtained from a detecting means which detects the torque of the stator (3) of the motor (1), the stator (3) is supported by a stationary system (5) so that the stator (3) can be rotated around a driving shaft (6), and the detecting means (11) is provided. When the load on the motor (1) increases, the transmission of the torque of the motor (1) to the reaction system (4) of the motor (1) from the action system (3) of the motor (1) is obstructed and, as a result, the stator (3) itself rotates against the stationary system (5) by reaction. When the stator (3) rotates, the detecting means (11) detects the torque of the stator (3) and stops, accelerates, decelerates, or inverts the rotation of the motor (1).</p> |
