Abstract | In a rotary electric machine, a modulation signal generator generates a modulation signal including information indicative of rotation of a rotor based on change of a voltage at an output end of a stator winding, and outputs the modulation signal. A rectifying unit alternately turns on and off the switch to rectify the voltage at an output end of the stator winding, thus generating a rectified voltage. An excitation current supplying circuit is communicably connected to the modulation signal generator via a communication line, and starts a supply of an excitation current to the excitation winding of the rotor to induce a rotating magnetic field in the stator winding when the modulation signal output from the modulation signal generator is input thereto via the communication line. |
