A rotary electrical machine such as an alternator, in particular for a motor vehicle. This machine is adaptable to various types of motor vehicle engine and comprises removable lugs () for fixing the machine to a fixed support such as a support secured to the vehicle engine and which are able to be mounted on the peripheral face of at least the front bearing (), each between two lateral support faces () provided on this peripheral surface at a predetermined distance from each other in the peripheral direction of the bearing. The lateral support face () is formed by the lateral face of an area of protruding material (), which constitutes an alternator assembly area, and the fixing lug () is disposed between two lateral support faces () opposite each other and belonging to two adjacent protruding areas ().

Rotating electrical machine such as an alternator adaptable to different types of motor vehicles engines

The invention provides an alternator for motor vehicles, in particular having a dissipator with one or more orifices designed to receive one or more press-fit diodes. An adaptor generally in the form of a disk has an outline enabling it to be engaged as a press-fit in a respective orifice of the dissipator. The adaptor has at least one plane face enabling a solder-mounting diode to be soldered thereto. The invention also includes the adaptor itself.

Alternator including adaptors for rectifier bridge diodes, in particular

An alternator for a motor vehicle has a rectifier bridge with positive diodes which are received in holes formed in a thermally conductive sector, which is fixed to an end plate of the alternator casing and which constitutes a thermal dissipator for the rectifier bridge. The rectifier bridge further includes a second sector of thermally conductive material, which is fixed to the first sector over the holes in the latter in which the positive diodes are received.
