The method is for producing a curved metal sheet strip for manufacturing a stator or rotor motor frame. The method comprises the steps of (a) cutting an elongated, substantially linear strip (8) from a metal sheet (a), the strip having two longitudinal sides and extending in a plane, the strip having an elongated band section (13) provided with a series of regularly spaced apart teeth (14) along one of the longitudinal sides; and (b) incurvating each portion of the band section joining two adjacent teeth in a direction perpendicular to the plane in such a manner that each portion has an increasing radius from one of the longitudinal sides to the other longitudinal side, thereby providing the curved metal sheet strip. According to the present invention, there is also provided a curved metal sheet strip. |
