PROBLEM TO BE SOLVED: To obtain an efficient motor-operated wheel driving apparatus having a small number of parts. SOLUTION: A rotor 17 of a motor 10 has a pair of rotor yokes 20a and 20b, which have the irregularity parts in the specified pitch at the outer surfaces and formed of soft magnetic material, and a driving magnet 21, which is arranged in the holding pattern between the rotor yokes 20a and 20b and has the single magnetic poles at the upper and rear surfaced. The stator has a teeth part, which has the irregularity parts in the specified pitch at the surfaces facing the outer surfaces of the rotor yokes 20a and 20b and is formed of soft magnetic material, a winding part, which is connected to the teeth parts, is formed thinly than the teeth part, has the pattern wherein the opposite sides with respect to the teeth part are mutually connected, and is formed of soft magnetic material, and an armature winding wound around the winding part. The teeth part and the winding part are arranged in the direction other than the direction of the grounding surface of a wheel. |
