Abstract
The rotor of an electric rotary machine is provided with two identical transmitting devices each including an amplitude modulator and a transmitting antenna. One of the modulators modulates a carrier with clock pulses while the other modulator modulates the same carrier with a data signal from the rotor expressed by a binary digital code including pulses identical in both shape and phase to the clock pulses. The transmitting antennas are disposed symmetrically with respect to a receiving antenna located externally of the rotor to induce the two modulated carriers substantially in phase across the receiving antenna.
