Apparatus for winding and terminating dynamo electric machine cores
First Claim
1. A method for winding and terminating coils wound with at least one electric wire one a core of a dynamo electric machine, the core having a longitudinal axis and being supported by a tubular support, the method comprising:
- winding a wire over a pulley wheel;
feeding the wire into a wire dispenser having a tubular portion for passage of the wire and an exit from where the wire reaches the core;
dispensing the wire from the wire dispenser;
translating the dispenser with respect to the core during winding or the termination of leads;
rotating the tubular support around a rotation axis;
recovering a portion of the wire returning from the pulley; and
applying torque in two directions on the pulley wheel as a function of the position of the dispenser in the translation and the position of the core in the rotation.

Abstract
An apparatus used in terminating and winding coils of a core of a dynamo electric machine. The coils being formed from at least an electric wire and the core having a longitudinal axis. The coils are wound by relatively moving a wire dispenser 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 for a termination connection to a termination structure of the core, such as a tang. The method avoids waste cut wire in the apparatus. The core is provided with a groove 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 is located, in order to intercept and align the wire with the groove. 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.
