摘要： A method, a processing line and components of the processing line for making a stator for electric motors, and the resultant stator. The conducting wire is wound in coils having at least one straight portion which is inserted into a corresponding stator sector. The sector is thus deformed to move its teeth close to each other and to close the straight portion of the coil. Multiple stator sectors so made are assembled together to form a stator complete with windings. During the production of stator sectors, the coils and/or stator sectors are rototranslated to bring them to the final position they must take inside the finished stator. Measures are provided to maximize the filling factor, to minimize torque ripple phenomena, to minimize noise and the vibrations of the electric motor achieved with the stator, and to maximize its performance, under other equal conditions.

摘要： A method for producing a skewed stator having a stator winding composed of shaped conductors includes providing a stator core including a plurality of slots extending from a first end-face to an opposing second end-face and have a skew in the circumferential direction. An arrangement is provided having at least one shaped conductor having two straight leg portions oriented parallel to one another and connected by a connecting portion. Also included is inserting the arrangement into the stator core with the skewed slots at the first end-face by relative movement in the axial direction between the stator core and the arrangement, so that the leg portions of the at least one shaped conductor are bent as a result of the relative movement in such a way that the shape of the leg portions inserted into the stator core acquires a skew which corresponds to the skew of the slots.

摘要： In a method for producing a stator for an electric rotating machine, first material layers of a first metal material are produced from a green body by a sintering process. The first material layers of the first metal material are stacked to form a toothed arrangement comprised of a plurality of radially oriented teeth and an inner ring to connect the teeth. Each of the first material layers has a first thickness in a range of 10 μm to 250 μm, in particular in a range of 10 μm to 100 μm. Second material layers of a second metal material are stacked to form a yoke, with the first metal material having a saturation induction which is higher than a saturation induction of the second metal material. The yoke is joined to the toothed arrangement to form a material layer structure, and the inner ring is removed.
