摘要： An electric wire shaping apparatus includes a pair of male and female shaping dies and a pressing mechanism. Each of the male and female shaping dies has a shaping surface that includes a plurality of straight parts and a plurality of bent parts. The pressing mechanism moves one of the male and female shaping dies toward the other, thereby pressing a turn portion of an electric wire between the shaping surfaces of the male and female shaping dies in a width-wise direction of the turn portion. Furthermore, the male and female shaping dies are so configured that when they are located closest to each other, a gap W2 between a corresponding pair of the bent parts of the shaping surfaces of the male and female shaping dies is different in size from a gap W1 between a corresponding pair of the straight parts of the shaping surfaces.

摘要： An electric wire shaping apparatus is disclosed for shaping an electric wire for a stator coil. The electric wire includes a turn portion that is to be located outside of slots of a stator core and a pair of straight portions that are connected by the turn portion and to be respectively received in two of the slots. The interval between the straight portions defines a coil pitch. The apparatus includes a shaping mechanism and a pair of coil pitch keeping mechanisms. The shaping mechanism presses the turn portion of the electric wire in its width-wise direction, thereby shaping the turn portion to have a desired shape. The coil pitch keeping mechanisms respectively press the straight portions of the electric wire toward the inside space between the straight portions, thereby preventing the interval between the straight portions from being changed by the pressing of the turn portion.

摘要： A stator which may be employed in an electric rotating machine. The stator includes a stator winding which includes in-slot portions disposed in slots of a stator core. The in-slot portions are arrayed in each of the slots in a form of multiple layers aligned in a radial direction of the stator core. The stator winding is made up of a first winding and a second winding which are connected together through a joint. The first winding is defined by a portion of the stator winding between the joint and an end of the stator winding which is to be connected to an external. The second winding includes the in-slot portion placed within at least one of the slots as an outermost layer that is one of the layers placed most outwardly in the radial direction of the stator core. This results in a great decrease in leakage current.

摘要： A tapered cage coil is prepared, having a small-diameter top coil end 101 and a large-diameter base coil end. The tapered cage coil is axially inserted into a stator core. Then, the tapered cage coil is radially expanded to thrust slot-accommodated portions of the coil into slots of the stator core. This can eliminate the necessity of deforming the base coil end to thereby facilitate the manufacturing procedures. At the same time, possible spring back can be mitigated.

摘要： A turn part of a lead wire includes a projection part, a slope part and a second bent part. The projection part projects from a first slot to a direction parallel to an axial direction of the stator core. The slope part is diagonally extended at an angle of less than 90 degrees aiming to a Kth slot. The Kth slot is separated from the first slot at a specific interval via a first bent part that is bent in a circumferential direction from a tip of the projection part. The second bent part is connected with the slot accommodation part accommodated in the Kth slot, and is bent to the direction parallel to the axial direction of the stator core from a tip of the slope part.
