INTERCONNECTION ELEMENT FOR CONNECTION OF STATOR COILS
First Claim
1. Interconnection element (24) for connection of stator coils of a polyphase rotary electrical machine (2), comprising a plurality of axially stacked conductive layers, including the same number of solid base layers (26, 28, 30), and additional layers (32, 34, 36) each formed by a plurality of parts of rings, each of said parts of rings not covering all of the periphery of the stator, each of these conductive layers supporting inner connection lugs (40) for connection of the coils, and outer connection lugs (48, 50) for connection to connected electrical equipment (4, 20), the number of base layers and additional layers being equal to the number of phases of the machine on which the interconnection element is added.
