Abstract:
An electrically commutated actuator and control system has a stator and a shaft that is movable with respect to the stator. A plurality of magnets movable with the shaft provide a first magnetic flux, and an electric current in at least one coil defined on the stator provides a second magnetic flux. The second magnetic flux is controlled in response to the first input so that the second magnetic flux has a predetermined phase with respect to the first magnetic flux. The second magnetic flux is controlled in response to the second input so that the phase of the second magnetic flux with respect to the first magnetic flux varies from the predetermined phase.
