Abstract
Vengono proposti un procedimento ed un dispositivo per impostare la coppia di cortocircuito in motori elettrici (11) specialmente motori di impostazione. A tale scopo viene misurata la coppia di cortocircuito (Mki) del motore elettrico (11) e questa viene raffrontata con una coppia prescritta (Mks) preassegnata. Successivamente viene calcolata la corrente di cortocircuito prescritta (Iks), necessaria per il raggiungimento della coppia prescritta, laddove in dipendenza del valore calcolato viene memorizzato un dato preliminare per la corrente di cortocircuito prescritta (lks) in un dispositivo di comando elettronico (10) per il motore elettrico (11). A tale scopo il dispositivo contiene una memoria (16) nel dispositivo di comando (10) per preassegnare il valore desiderato. In tal modo anche motori della produzione in serie, per i quali sussistono tolleranze relativamente grandi degli elementi costruttivi, in maniera semplice ed economica possono essere dotati di una coppia di cortocircuito nell'ambito di un modesto intervallo di tolleranza.
