Patent ID: 8441163

Claim:
A rotating electric machine with homopolar double excitation, wherein the electric machine comprises: a stator comprising a central core, a stator coil, and two excitation coils positioned on opposite sides of said core generating a double excitation flux, said excitation coils surrounding said stator coil; and a rotor comprising: a central solid part having isotropic magnetic behavior to facilitate the circulation of the double excitation flux relative to the axis of the rotor, an annular part of lamellar material installed around the central solid part, and permanent magnets with magnetization oriented radially relative to the axis of the rotor; said permanent magnets each being formed by a U-shaped assembly of magnets; said magnets having the same polarization, and wherein two consecutive magnets are separated by a magnetic space to allow circulation of the double excitation flux in the rotor between the magnets.
