E' basato su IRIS, il nuovo sistema di gestione dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall’ateneo
EnglishThe brush wear in small rating, high speed, universal motors is analysed, developing a model for its estimation, as a function of the operating and constructive quantities. Particular attention is devoted to the effect of the turns distribution in the armature slots: to this aim, two universal motors are considered, with the same constructive quantities, except for the number of turns of the two coil sections per layer-slot; in the former motor this number is the same, in the latter different, maintaining nevertheless the same sum. Using a suited equivalent network to study the commutation, the significant figures of merit are found out, giving an explanation of the different wear in the two cases
