Abstract:
A field coil type rotating electric machine includes a field coil having a serially-connected coil section pair consisting of first and second coil sections, a diode having its cathode and anode respectively connected to opposite ends of the serially-connected coil section pair, a rotating shaft, and a rotor having main pole portions radially protruding from a rotor core. In the rotating electric machine, there are formed both a series resonance circuit including the first coil section and at least one capacitor and a parallel resonance circuit including the second coil section and the at least one capacitor. Electronic components electrically connected with the field coil, which include the diode and the at least one capacitor, are arranged so that an overall center of gravity of all the electronic components is located closer than each of centers of gravity of the electronic components to a central axis of the rotating shaft.
