Abstract

Viene proposta una macchina elettrica, preferibilmente un generatore di corrente trifase per autoveicoli, nella quale il pacco (11) di lamierini dello statore è serrato fra due scudi quali metà (13, 14) di carcassa mediante viti di serraggio (15). Per la riduzione del rumore da vibrazioni eccitate magneticamente delle lamelle (11a) in lamiera viene proposto di collegare rigidamente tra loro le lamelle (11a) in lamiera serrate fra le superfici di appoggio e di centratura (31, 34) delle due metà (13, 14) di carcassa mediante rispettivamente almeno due cordoni di saldatura (32) simmetrici rispetto alle viti di serraggio (15) disposti a distanza esigua.(Figura 2).An electric machine is proposed, preferably a three-phase current generator for motor vehicles, in which the stator sheet pack (11) is clamped between two shields such as half (13, 14) of the casing by means of clamping screws (15). To reduce the noise from magnetically excited vibrations of the sheet metal slats (11a), it is proposed to rigidly connect the sheet metal slats (11a) clamped between the support and centering surfaces (31, 34) of the two halves (13, 14) of the casing by means of respectively at least two welding seams (32) symmetrical with respect to the tightening screws (15) arranged at a small distance (Figure 2).
