A peeling device () includes a first peeling unit () and a second peeling unit (). When an upper peeling die () and a lower peeling die () of the first peeling unit () are moved forward, an insulating coating () is peeled off from upper and lower surface of a coil conductor wire (), and a conductive portion () is cut from the upper surface and the lower surface of the coil conductor wire (). The conductive portion () is formed to have exposed portions () and recessed portions () cut in a trapezoidal shape. A front peeling die () and a rear peeling die () of the second peeling unit () are moved downward while the recessed portion () is placed on and pressed against a second receiving section () of a cradle (), which peels off the insulating coating () and cuts the conductive portion ().

Peeling device and method

A method for bonding electrical conductors is provided that is capable of suppressing a power source capacity when assembling a stator having a specific structure. First, coil piecesare arranged in contact with bonding portions of a slot coilinserted in a slot of a stator iron corevia a metal paste. Subsequently, an electrical current is applied using a pair of electrodesA andB in the axial direction (upward and downward in the figures) of the slot coilwhile contact portionsbetween the slot coiland the coil piecesare pressed in an axial direction of the slot coilAs a result, electricity flows in the axial direction the coil piece(a direction of an arrow X in the figures).

Method for bonding electrical conductors

A control device moves a split claw () holding a projecting portion () of an eighth-layer coil segment () in a counterclockwise direction D. At this time, the control device moves first to third extended blades () to () in an outward direction Dso that the projecting portion () of the eighth-layer coil segment () is bent in the outward direction D. Then, the control device moves the first to third extended blades () to () in an inward direction D. Through the above steps, the projecting portion () of the eighth-layer coil segment () is bent in the counterclockwise direction Dwhile being bent in the outward direction D. As a result, a return force tending to return in the inward direction Dis generated by an elastic deformation force.
