Abstract

Apparecchio frigorifero o congelatore, preferibilmente di tipo domestico, dotato di almeno un compressore alternativo ermetico, provvisto di motore elettrico di azionamento del tipo senza spazzole e di dispositivo di controllo elettronico di frequenza atto ad azionare detto motore ad una pluralità di velocità differenti preselezionabili, ove detto compressore è dotato di una protezione costituita da una velocità minima (Vmin) preselezionabile di detto motore sotto la quale detto controllo interrompe il funzionamento di detto motore. Inoltre detto controllo è atto a selezionare una velocità del motore diversa (Vmax) da qualsiasi velocità preselezionata quando viene inviato a detto controllo un comando esterno o una particolare combinazione di segnali rappresentativi del funzionamento del frigorifero.
