20140215806 | STATOR MANUFACTURING METHOD AND STATOR MANUFACTURING APPARATUS - A stator manufacturing method involving a coil arrangement process, a coil deformation process, and a coil insertion process. During the coil arrangement process, a plurality of annular conductors constituting the coil are disposed in a coil holder such that a first portion of each of the annular conductors is inserted into a first catching gap formed between the blades, a second portion of each of the annular conductors is inserted into a second catching gap that is away from the first catching gap by a predetermined pitch. During the coil deformation process the coupling portion of each of the plurality of annular conductors is deformed by moving the coil pusher in the axial direction along the blades. During the coil insertion process the first and second portion of each of the annular conductors are inserted into the slots by further moving the coil pusher in the axial direction. | 08-07-2014 |
