1880 Jrnl. Soc. Telegr. Engineers 9 142 The more recent progress made by Mr. Gramme in combining into one his two admirable continuous and alternate current machines, and producing his self-exciting machine, is also a great improvement.

1922 R. Glazebrook Dict. Appl. Physics II. 195/1 The great advantage of direct-current machines is that: (i) They can be made self-exciting.

1949 Proc. Royal Soc. A. 197 433 Thermal convection is shown to be likely to occur in the core... The whole process resembles that occurring in a self-exciting dynamo.

1971 Sci. Amer. Dec. 80/1 The influence of the Coriolis force on the motions of the outer core is thought to be critical to the operation of the self-exciting dynamo that generates the main magnetic field of the earth.

2012 Proc. Royal Soc. A. 468 288 In this paper, we extend our previous template analysis of a self-exciting Faraday disc dynamo.

1943 Gloss. Terms Telecomm. (B.S.I.) 69 Self-exciting sender, a radio sender in which the oscillator determining the frequency also generates the radio-frequency power.

2004 Weather Radar 297 Magnetron. A self-exciting oscillator tube generating pulses, the phase of which is random. Used to produce the radio frequency signal transmitted by some radars.
