Abstract
A stator winding is manufactured by a forming step, a winding step, and a expanding step. In the forming step, an S-shaped offset shape is formed on a conductor part corresponding to a coil end part. Thereby, in a coil end part, it is possible to provide an expected shape stably at the coil end part. The conductor is wound around a bobbin in the winding step. In the winding step, a twisted shape is given to the conductor parts to be the inclined part of the coil end and the conductor part to be accommodated in a slot. In the expanding step, a preform product removed from the bobbin is expanded into a shape of the stator winding.
