Abstract
The invention concerns a polyphase motor comprising M phases, M being equal to 2 or 3, the motor consisting of a stator part () excited by electric coils and by a magnetized rotor (). The invention is characterized in that the rotor () has a disc-shaped magnetized part with R pairs of alternately poles magnetized in alternating directions in the thickness, R being equal to n*(M+1) or 5*n, and said stator part () has S poles, some of which excited at least by an electric coil, S being equal to 8*n, for even M, and 9*n for odd M, n being an integer not less than 1.
