self-excite

English

Etymology

Verb

self-excite (third-person singular simple present self-excites, present participle self-exciting, simple past and past participle self-excited)

To energize or excite (the field magnets of a dynamo) by induction from the residual magnetism of its cores, leading all or a part of the current thus produced through the field-magnet coils.
- 1994, The Free-energy Device Handbook, page 116:
  Using metal rollers to simulate the earth's cylindrical eddy currents, the team found some interesting results after beginning with a few viscosity problems. "...a more efficient geometry was found, so efficient that the dynamo would self-excite in a completely homogeneous state (i.e. with no insulation ) at a much lower rotor speed than was believed possible" [12] .
- 2005, Mukund R. Patel, Wind and Solar Power Systems, page 98:
  The induction generator can self-excite using the external capacitor only if the rotor has an adequate remnant magnetic field.
- 2016, Bikash Pandey, ‎Ajoy Karki, Hydroelectric Energy: Renewable Energy and the Environment, page 342:
  This so-called "field flashing" reestablishes the residual magnetism to allow the generator to self-excite.
To self-generate a state of excitation.
- 1998, Robert Jervis, System Effects: Complexity in Political and Social Life, page 150:
  Thus warning systems can self-excite when they go on alert: When a decision maker thinks that an attack is likely, he will place more credence in reports indicating that a war is imminent than he would if the same information were received in a period of calm, and actions of the other side that usually would be missed or seen as innocent will be perceived as evincing hostile intentions.
- 2013, Larry Squire, Fundamental Neuroscience, page 858:
  In a subsequent revision of the RI hypothesis, mutually excitatory interactions between cholinergic and glutamatergic neurons underlie the rapidly escalating firing of pontine reticular REM-on neurons during REM sleep and cholinergic REM-on cells both self-excite and self-inhibit via cholinergic autoreceptors.
- 2019, Peter Tiňo, Bill G. Home, C. Lee Giles, “Stability and Bifurcation Analysis of Fixed Points in Discrete Time Recurrent Neural Networks with Two Neurons”, in Joseph T. DeWitte, editor, Proceedings of the 1995 World Congress on Neural Networks, page 62:
  When both neurons self-excite themselves and have the same mutual interaction pattern, the mechanism of creation of a new attractive fixed point is shown to be that of saddle node bifurcation.
