ABSTRACT:
A throttle plate actuator and apparatus for controlling the pivotal position of a carburetor or throttle body throttle plate. The throttle plate actuator includes a rotor having a rotatable shaft mounted in a housing. First and second permanent magnets of opposite polarity directions are mounted on the rotatable shaft in spaced, facing relationship. A stator in the form of an electromagnet constructed of first and second pole pieces normally surrounds the facing portions of the first and second permanent magnets. At least one electrical conductor is wound in a plurality of turns to form a winding about each pole piece. When energized, the windings induced a magnetic field in the pole pieces which generate a predetermined magnetic torque proportional to the amount of current flowing through the windings to overcome the bias of the return spring attached to the throttle plate so as to rotate the rotor and attached throttle plate a predetermined angular amount. The throttle plate actuator apparatus includes a control unit responsive to accelerator pedal position and the throttle plate position and parameters stored in a control program to control the amount of current supplied to the windings of the stator.
