PURPOSE:To assemble a motor into an automatic controller and to quicken response, by rotating a second stator through a cylinder drive mechanism which employs a motor as a drive source. CONSTITUTION:A rolling rod 21 is secured to a part of outer circumference of a second stator B. Tip of a motor cylinder 23 is coupled through a universal joint 22 with the rolling rod 21. Furthermore, a universal joint 25 for coupling a brake device 24 and a frame seat 26 with the motor cylinder 23 is provided. Control circuit 32 of the motor cylinder 23 controls the motor cylinder 23 to displace the second stator B by a predetermined amount or hold the second stator B. When the second stator B is required to be fixed at a predetermined position, the brake device 24 associated with the motor cylinder 23 functions to hold the second stator B. |
