摘要： Disclosed is an apparatus for rolling a substantially planar electric wire by more than one turn into a spiral shape. The apparatus includes an inner pressing member having an outer surface, an intermediate pressing member having radially inner and outer surfaces, and an outer pressing member having an inner surface. The inner and intermediate pressing members together press a first part of the electric wire between the outer surface of the inner pressing member and the inner surface of the intermediate pressing member, thereby plastically deforming the first part to extend along the outer surface of the inner pressing member. The intermediate and outer pressing members together press a second part of the electric wire between the outer surface of the intermediate pressing member and the inner surface of the outer pressing member, thereby plastically deforming the second part to extend along the outer surface of the intermediate pressing member.

摘要： A method of manufacturing a stator includes the steps of: (1) forming substantially planar electric wires each of which includes in-slot portions to be received in slots of a stator core and turn portions to be located outside the slots to connect adjacent pairs of the in-slot portions; (2) rolling each of the planar electric wires by more than one turn into a spiral shape; (3) forming a stator coil by assembling the rolled electric wires through elastic deformation thereof; and (4) assembling the stator core and the stator coil to form the stator. Further, in the rolling step, each of the planar electric wires is rolled by plastically deforming the turn portions into circumferentially-extending sections each having a predetermined curvature. Furthermore, a curvature ratio of a radially-outermost one of the circumferentially-extending sections is set to be greater than that of a radially-innermost one of the same.

摘要： A method of welding a plurality of conductors to form a winding extending through an annular stator core. The conductors are inserted into slots formed in the stator core to have coil ends extending outside an end surface of the stator core. A plurality of pairs of the coil ends are arranged in diagonal arrays extending diagonally with respect to a radial direction of the stator core. The method inserts a first electrode into a gap between adjacent two of the diagonal arrays and then brings a second electrode close to one of the adjacent two of the diagonal arrays to arc-weld, the pairs of the coil ends. This welding method enables the welding of the coil ends arrayed in the above layout efficiently while keeping the electrical insulation between the pairs of the coil ends.
