Abstract

Il dispositivo circuitale per controllare un motore asincrono trifase alimentato da una sorgente di corrente continua comprende un inverter dotato di uno stadio di pilotaggio controllato da un'unità a microprocessore in modo da fornire durante la fase di avviamento una tensione avente una frequenza progressivamente crescente fino alla frequenza di lavoro.L'unità a microprocessore è atta a diminuire o aumentare la frequenza della tensione di alimentazione del motore in funzione dei valori di tensione rilevati da un sensore di tensione in modo da mantenere il valore della coppia motrice prossimo a quello di lavoro.
