摘要： In a method of manufacturing a stator core of an electric rotating machine, a cylindrical laminated core is formed by thinning a side portion of a steel plate with magnetic pole teeth and helically winding the steel sheet, and the stator core is manufactured by performing ironing for the laminated core. This laminated core has steel sheets aligned along the axial direction thereof, and the sheets have respective thinned outer end portions spaced apart from one another on the outer side of the laminated core. In the ironing, the thinned outer end portions of the steel sheets are brought into contact with one another in a forming apparatus, and an ironing load is given to the thinned outer end portions to shorten lengths of the thinned outer end portions in the radial direction of the laminated core at a predetermined value.

摘要： 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.

摘要： In a rotor for a rotating electrical machine, a flange of an insulating bobbin is formed with a first hook portion and a second hook portion. The first hook portion directs a lead of a field coil both against the winding direction of the field coil and radially inward. The first hook portion has a first groove in which is hooked a proximal portion of the lead. The second hook portion directs the lead axially outward. The second hook portion has a second groove which has an open end on a radially inner periphery of the second hook portion, a closed end positioned radially outward of the open end, and a neck between the open and closed ends. The second hook portion has an intermediate portion of the lead hooked in the second groove between the neck and closed end of the second groove.
