ABSTRACT:
An electrically controlled actuator includes a rotor detachably mounted on a rotating shaft, and a stator disposed around the rotor. A fluid flow plate is mounted on the rotating shaft and opens/closes a fluid passageway. A spiral spring is mounted on one end of the rotating shaft. When the rotor is rotated, the fluid flow plate regulates a fluid flow in the fluid passageway. An electrical control current is received in the actuator and is converted to a magnetic torque to rotate the rotor, while the spiral spring is increased in tension. The spiral spring opposes the rotation of the rotor so as to control the position of the fluid flow plate. The rotor includes two symmetric tips extended from two curved outer surfaces at two leading edges of the rotor. An air gap is defined between the inner surfaces of the stator and the outer surfaces of the rotor. The air gap becomes narrower when the rotor is rotated into a space between two poles of the stator.
