Abstract: An exemplary system includes a first electric motor and a second electric motor, which are coupled mechanically to one another via a common string of the system. The string has a torsional natural oscillation at a natural frequency. A first oscillating torque acts on the string by the first electric motor and a second oscillating torque acts on the string by the second electric motor. The second electric motor is arranged with respect to the first electric motor such that the effect of the second oscillating torque on the string results in damping of the excitation of the natural oscillation owing to the first oscillating torque.

Abstract: Information from a real sensor and a virtual sensor are fused to form a hybrid sensor. Control signals (and/or the absolute value of the control signals) applied to an actuator are accumulated and converted to a position the actuator should be in based on the accumulated control signals to form the virtual sensor. The actuator position from the virtual sensor is fused with an actuator position from a real sensor to form the hybrid sensor. Small periodic corrections can be made to the accumulating control signals to maintain or achieve, if possible, correlation between the virtual sensor and the real sensor over time. The corrections slowly decrement errors in the actuator position indicated by the virtual sensor. Accumulating numerical errors in the accumulating control signals are reduced and the significance of long past events is de-emphasized by a forgetting factor (kff) used at defined periods of time (tff).

Abstract: A device for installing a modular crawler into an air gap of rotating electrical machinery and removing the crawler from the air gap has a reconfigurable handle attached to a curved head made from metallic material. The crawler is magnetically attached to the curved head when it is desired to insert the crawler into the air gap or remove the crawler from the air gap. The head can be rolled in the field into the curvature needed to match the stator's inner surface so that the installation device can easily be inserted in the air gap. The handle has several joints that can be adjusted in the field as needed for the best reachability. A camera is mounted on the curved head so that an operator can see the interface region between the curved head, crawler and air gap.
