主权项 1. A single-phase induction motor comprising: a stator fixed in a cylindrical frame by shrink-fitting or press-fitting; a main winding wire and an auxiliary winding wire provided on the stator; and a rotor provided on an inner circumferential side of the stator, wherein the stator is configured such that in a cross-section of the stator, an arc-shaped arc portion and a linear cutout portion are formed on an outer circumference of the stator; the arc portion is provided on the outer circumference of the stator in a magnetic pole direction of the main winding wire with respect to a center of the stator; and a relief portion for reducing a contact area between the arc portion and an inner circumferential surface of the frame is formed on the arc portion.
