A rotor of an alternating current generator has a field excitation assembly supported on a rotor shaft including a pair of rotor segments forming a cavity therein, a bobbin made of an insulating resin disposed in the cavity and a field excitation coil wound on the bobbin. The bobbin has a cylindrical portion and a pair of flanged portions at both ends thereof for forming room for the field excitation coil. On one of the flanged portion, a pair of projections are integrally formed therewith extending axially and outwardly, which are press-fitted into a pair of through holes formed on one of the rotor segments. Each of the projections is formed with not only an axially extending groove for receiving a field coil terminal, but a radially and axially extending slit communicating the outside of the projection with the groove for guiding and receiving a coil starting or terminating end of the field coil. The coil ends are hung on the field coil terminals press-fitted into the projections, whereby neither the coil starting nor terminating end is drawn back out of the bobbin even before the bobbin is assembled in the rotor segments.

An apparatus terminates and winds coils of a core of a dynamo electric machine. The coils are formed from at least an electric wire and the core has a longitudinal axis. The apparatus includes a wire dispenser which translates and rotates with respect to a core to wind the coils. At least a stretch of wire extends from the coil; and the stretch of wire includes a portion for a termination connection to a termination structure of the core, such as a tang terminal. The core has a groove at an end to receive at least a wire in the path of the wire to terminate the coils. The apparatus comprises a wire deflector positioned adjacent the end of the core, where the groove is located, in order to intercept and align the wire with the groove. The apparatus avoids waste cut wire.

A method for manufacturing a stator includes preparing a stator core having a plurality of teeth, a plurality of coils having a plurality of lead lines, a substrate having a plurality of connecting portions, and a plurality of positioning jigs having restraining portions. The method includes positioning the substrate and the lead lines so that distal portions of the lead lines are separated from the connecting portions in at least one of a radial direction and a circumferential direction. The method further includes inserting the lead lines in the restraining portions, aligning the distal portions of the lead lines with the corresponding connecting portions using the positioning jigs, inserting the lead lines into the corresponding connecting portions, and electrically connecting the lead lines inserted in the connecting portions to the corresponding connecting portions.

Method and Apparatus are provided for automatically disposing plural wires along predetermined trajectories, wherein the plural wires extend from coils wound in slots of dynamoelectric machine cores. Plural wires forming leads are located in predetermined positions and caused to extend along predetermined directions by means of manipulating equipment and tooling which operates automatically. In addition, the equipment and tooling cause the plural wires to become twisted and cut to form portions for connection to terminals. The tooling is provided with reference surfaces and seats which are used to bend the plural wires along the predetermined trajectories and to provide a position constraint for the portions becoming twisted. Apparatus can be provided for positioning portions of a plurality of restraining members in the spacing existing between the bridges of the coils and the end faces of a dynamo electric machine core.
