摘要： A rotor assembly includes a rotor core having winding slots, and one or more coils, which have slot-inserted segments included in the winding slots, and first and second end-turn segments external to the winding slots and located around opposite axial ends of the rotor core, respectively. The rotor assembly further includes a first containment band located around at least a portion of the first end-turn segments and configured to prevent the first end-turn segments from moving away from the rotor core radially, a second containment band located around at least a portion of the second end-turn segments and configured to prevent the second end-turn segments from moving away from the rotor core radially, and one or more sticks mounted in one or more of the winding slots, respectively. The first and second containment bands are retained via the sticks against moving away axially.

摘要： A method for forming a blanked piece from a material, where the blanked piece includes a production area having a through hole and at least one caulking and connection area protruding inside the through hole. The method includes forming a blanking hole in the material in a prescribed outline, placing a guide member in the through hole, where the guide member has an abutting part contacting a protrusion of the material formed along the outline of the blanking hole. The method further includes cutting and separating the material to blank or stamp out downward the caulking and connection area, pushing back the caulking and connection area, and temporarily connecting the caulking and connection area to the material; and blanking or stamping an outer configuration of the product area from the material to which the caulking and connection area is temporarily connected.
