Abstract
A method for terminating and winding coils of a core (20) of a dynamo electric machine. The coils being formed from at least an electric wire (W) and the core (20) having a longitudinal axis (20′). The coils (19) are wound by relatively moving a wire dispenser (21) with respect to a core with relative motions of translation and rotation; at least a stretch of wire extends from the coil and the stretch of wire is provided with a portion (W4) for a termination connection to a termination structure (22) of the core (20) such as a tang. The method avoids waste cut wire in the apparatus. The core is provided with a groove (120) at an end to receive at least a wire in the path of the wire for the termination of the coils. The apparatus comprises a wire deflector positioned adjacent the end of the core, where the groove (120) is located, in order to intercept and align the wire with the groove (120). The apparatus can comprise a device for applying torques in two directions on a pulley wheel for feeding wire as a function of the position of the dispenser in the translation and the position of the core in the rotations.
