    • A claw-pole motor includes a rotor having permanent magnets; and a stator having stator rings assigned to three phases, which are coaxially stacked along the same axis. Winding attachment portions are formed between adjacent stator rings, and an annular winding is installed in each winding attachment portion for generating a magnetic field for rotating the rotor. Each stator ring has a main body and claw-shaped induction poles which protrude from the main body in radial directions. The claw-shaped induction poles of the three phases are serially arranged along a circumference of the stator rings and also face the permanent magnets. An interval between adjacent claw-shaped induction poles along the circumference of predetermined two of the stator rings of the three phases is smaller than an interval between adjacent claw-shaped induction poles along the circumference of any other pair of the stator rings.
