excitation

The act of exciting or putting in motion; the act of rousing up or awakening.

Generator excitation is obtained by a combination of the separately-excited and self-excited fields, and the output is controlled by a resistance in the separate field circuit adjusted by the load regulator under the control of the engine governor.

Wheelslip automatically causes the main generator field excitation to be reduced; the load regulator is forced back to minimum excitation and, if operating in one of the two stages of traction motor field divert, causes reversion to full field.

The act of producing excitement (stimulation); also, the excitement produced.

Baiae: An ancient Roman pleasure resort [...]. It was the focal point of all kinds fo erotic experiments, unbridled debauchery, amorous intrigues and excitations, sexual encounters and aberrations.
