ABSTRACT:
The invention relates to an electrical machine. The stator 1 is a delay line, in the form of a low-pass filter in the example, formed by inductance 11 and capacitors 12 connected between these inductances and the common conductor 13. The rotor 2 comprises dissipating elements 22 incorporated in circuits 26, separate in the example, and having a common point 25. It is put in movement by a motor. The machine operates as a high-gain amplifier having a wide band of high-frequency signals applied to the input 14 of the stator, separated from the output 15 by the decoupling zone 30. High powers are obtainable.
Application to installations for testing vibration of industrial equipment and to high-power longwave radio transmission.
