MOTOR

PROBLEM TO BE SOLVED: To reduce the weight of a motor by reducing the quantity of iron while maintaining the characteristics and taking into account windability. SOLUTION: The motor comprises a stator 2 obtained by applying windings 7 and 8 to the salient pole parts 3 and 4 of the stator core comprising the salient pole parts 3 and 4 and yoke parts 5 and 6 linking the root parts thereof, and a rotor 1 held rotatably on the inner circumference of the stator 2 while facing the salient pole parts 3 and 4 wherein the yoke part has a part proximate to the rotor than the yoke part at the root of the salient pole and the widths 5b and 6b of the yoke parts 5 and 6 on the forward side in the rotational direction of the proximate part are wider than he widths 5a and 6a of the yoke parts 5 and 6 on the rearward side in the rotational direction of the proximate part.
