Abstract
Apparatus and methods to damp electromechanical device vibration are disclosed. An example apparatus includes a damping filter to be coupled between terminals of an electromechanical device. The damping filter is to enable damping of non-control signal frequencies, and to not enable damping of control signal frequencies.
Claims19
An apparatus, comprising:
- a damping filter to be coupled between terminals of an electromechanical device, the damping filter to enable damping of non-control signal frequencies, and to not enable damping of control signal frequencies, the damping filter to be electrically coupled in series with a shorting coil that provides a shunt path to bypass a winding of the electromechanical device, the shorting coil magnetically coupled to the winding.
A system, comprising:
- an electromechanical device;
- a control system to control a state of the electromechanical device;
- a shorting coil to provide a shunt path to bypass a winding of the electromechanical device to provide a damping response for the electromechanical device, the shorting coil magnetically coupled to the winding;
- and
- a damping filter in series with the shorting coil to control a range of frequencies for the shorting coil damping response.
2 more elements
A method, comprising:
- magnetically coupling a shorting coil to a winding of an electromechanical device;
- and
- electrically coupling a passive filter in series with the shorting coil between terminals of the electromechanical device such that the shorting coil and the passive filter provide a shunt path to bypass the winding of the electromechanical device, the passive filter being configured to enable damping of non-control frequencies and to not enable damping of control frequencies of the shorting coil.
