Abstract
In una saldatrice a motore del tipo includente un alternatore di uscita avente un rotore condotto attorno ad un asse centrale e con una superficie cilindrica rivolta all'esterno ed uno statore con una superficie cilindrica che generalmente si adatta a detta superficie cilindrica del rotore e contenente in un numero di aperture all'interno, circonferenzialmente distanziate, fessure di avvolgimento che si estendono assialmente, in cui le fessure includono un primo gruppo atto a ricevere avvolgimenti per corrente di saldatura ed un secondo gruppo atto a ricevere avvolgimenti di circuito di potenza ausiliari, il perfezionamento in questa struttura, comportante la modificazione del primo gruppo di fessure come includenti mezzi strutturali per provocare un sostanziale aumento nella perdita di flusso nel primo gruppo di fessure, in confronto alla perdita di flusso fra il secondo gruppo di fessure. In questa maniera, la uscita di saldatura della saldatrice a motore ha una reattanza interna sostanziale e il circuito di potenza ausiliaria ha una reattanza interna ridotta, tutto nello stesso statore. Ciò riduce la necessità di un reattore esterno nel circuito di saldatura pilotato dalla saldatrice a motore e migliora la regolazione della tensione del circuito di potenza ausiliaria.
