    Abstract: During displacement of an actuating element to a target position, a brushless direct-current motor is driven by a driving commutation pattern derived from rotor position signals. After the target position is reached the brushless direct-current motor is transferred to a holding mode in which it is driven by a commutation pattern providing a required holding torque. In the holding mode the holding current necessary for providing the required holding torque is minimized by an iterative holding current reduction method to a holding current value guaranteeing the required holding torque.

    Abstract: An electrical machine having a stator and a rotor. The stator includes a core and a plurality of windings disposed on the core in a multiple-phase arrangement. The rotor is disposed adjacent to the stator to interact with the stator. A method of operating the motor includes applying a pulsed voltage differential to first and second terminals of the windings resulting in movement of the rotor; monitoring the back electromotive force (BEMF) of the windings to sense rotor movement; after the applying and monitoring steps, monitoring the BEMF of the windings to determine whether the rotor is rotating in a desired direction, and electrically commutating the motor when the rotor is rotating in the desired direction and zero or more other conditions exist.
