Abstract

Si propone un motore frazionale elettrico che serve ad azionare un ventilatore per il raffreddamento del motore a combustione interna di un autoveicolo. Il motore frazionale comprende una carcassa che presenta un'apertura ed è chiusa da un disco di supporto di materiale termoconduttivo facente parte della carcassa, al quale disco è associata almeno una parete di guida per spazzole di collettore facenti parte di un dispositivo di commutazione sistemato nella carcassa. Una buona trasmissione termica dalla spazzola del collettore alla carcassa del motore si ottiene con una regolare guida della spazzola se alla parete di guida, in corrispondenza del disco di supporto, è coordinata almeno un'ulteriore parete di guida e tra le pareti di guida e la spazzola del collettore, che si diparte dalle stesse scorrendo con poco gioco, vi è uno strato isolante termoconduttivo.(Figura 1).
