Patent ID: 8860282

Claim:
A polyphase motor having M phases, where M is equal to 2 or 3, the motor comprising: a rotor including a magnetized part in the form of a disk; a pair of complementary stator parts, each stator part is a monolithic part including axial teeth of trapezoidal shape with side flanks substantially perpendicular to the transverse plane of the motor and forming poles, the pair of stator parts configured to be excited by electric coils and the magnetized rotor, wherein the rotor has R pairs of poles magnetized along a thickness in alternate directions, R being equal to n*(M+1) or 5*n, the total number of trapezoidal teeth is S, S being equal to 8*n for even M and to 9*n for odd M, n being an integral number greater than or equal to 1, and one trapezoidal tooth out of three is wrapped by the electrical coil when M is odd and one trapezoidal tooth out of two is wrapped by the electrical coil when M is even.
