Abstract:
A flux commutating electrical machine comprising:a stator including at least one armature coil housed in at least one pair of notches; anda rotor including means for selectively establishing closed magnetic circuits around sections of said armature coil, said means for selectively establishing including at least one excitation permanent magnet adapted to establish a magnetic flux in a circumferential direction of said rotor and at least one excitation coil adapted to establish a localized variable magnetic flux in the same circumferential direction as the flux produced by said magnet, said magnet being housed in a first rotor part defining a first pair of rotor poles, said excitation coil being housed in a second rotor part defining a second pair of rotor poles, said first and second rotor parts being separated from each other by essentially magnetically non-conductive areas.
