To provide a manufacturing method of a divided stator which comprises a process for reducing a gap between electric wires by pressing an electric wire layer formed by winding the electric wires to a core in a core direction, and is suppressed in a problem such as the displacement of the electric wires, and a slide between the electric wires which occur at the pressing.
The manufacturing method of the divided stator comprises: a winding step for winding on the core an insulation-coated electric wire having a conductive wire and an insulation layer which coats the conductive wire layer, and forming the electric wire layer; and a compression process which presses the electric wire layer to the core direction. The manufacturing method of the divided stator is characterized in that the pressing is performed while a temperature is kept within the same range after the insulation-coated electric wire is heated to a temperature range in which a temperature is not lower than 160C, and lower than a melting point of the insulating layer. There are also provided a manufacturing method of a stator which uses the divided stator obtained by the manufacturing method of the divided stator, and a manufacturing method of a motor which uses the stator obtained by the manufacturing method of the stator.
