Abstract
A flux commutating electrical machine includes a stator and a rotor. The rotor selectively establishes closed magnetic circuits around sections of the armature coils. Excitation permanent magnets establish a magnetic flux closing on itself in a circumferential direction and excitation coils establish a localized variable magnetic flux in an opposite direction to that of the flux produced by the magnets. Each magnet is housed in a first rotor part defining a first pair of rotor poles, and the coils are disposed around a second rotor part ends of which define a second pair of poles. The rotor has between the adjacent first and second rotor parts third rotor parts forming with the first and second parts a circumferential magnetic conduction path.
