    Abstract: The disclosure discloses method that includes: step S1: manufacturing strip-shaped iron core; step S2: performing wire-winding around the wire-winding bodies with center line as axis to form stator winding; step S3: rolling strip-shaped iron core, on which winding has been performed through step S2, into outer ring with tooth portions as periphery, and connecting arc-shaped surfaces of all yoke portions to form inner ring, so that strip-shaped iron core has ring-shaped structure; step S4: machining tooth portions and yoke portions of strip-shaped iron core respectively, so that joints after strip-shaped iron core is rolled into circle are fixed to form stator iron core with integrated structure. The disclosure discloses outer rotor motor using the method. Compared with related art, by use of technical solutions of the disclosure, coils can be effectively wound neatly in wire slot, with high slot filling rate, simple process, and easy manufacturing.

    Abstract: An electric motor coil winder is provided. A cutting length of a wire used for an electric motor coil is controlled according to the location of a slot formed at a stator inside an electric motor so that a wasted wire can be reduced and a manufacturing cost and energy thus can be reduced, a cutting cover is installed at a cutting part to prevent a cut wire from popping up and protect the inside of the cutting part, and the length of a wire required for a process is set to enhance production efficiency.

    Abstract: 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.
