Patent ID: 7135802

Claim:
A claw pole motor stator comprising: teeth for N phases, wherein N is a natural number of 3 or more, juxtaposed in an axial direction; return paths for interconnecting the teeth for N phases; (N−1) annular slots formed between teeth for N phases; and coils for N phases disposed in the (N−1) annular slots, wherein a plurality of poles project radially inward from inner ends of the teeth for N phases, extend in said axial direction, wherein the poles for one of the N phases are at least partially overlapped by the poles of another of the N phases in the axial direction when viewed in a circumferential direction, wherein the poles for N phases are arranged in phase with each other, and magnets of the rotor are arranged so that magnetic poles of the same polar sign are displaced in the peripheral direction relative to the poles for each phase, and wherein generated magnetic fluxes are displaced by electrical angles of 360°/N.
