Abstract
An electrical damping system provides damping over a wide range of frequencies including high frequencies. The system includes a resistance in parallel with an electric motor or series connected resistance and capacitance in parallel with the electric motor. In another embodiment, an electrical damping system is provided for a motor having a delta or wye motor winding configuration.
