发明名称 MOTOR CONTROL SYSTEM
摘要 A technique facilitates control over the actuation of a device by utilizing a rotor and a corresponding stator system. The rotor is rotatably mounted in the stator system, and rotation of the rotor relative to the stator system is correlated with the volumetric displacement of the fluid passing between the rotor and the stator system. A control system is employed to control the angular displacement and/or torque of the rotor and/or the flow of fluid thereto.
