Patent ID: 7859147

Claim:
An electronic module for a reversible rotary electrical machine, said rotary electrical machine being defined by an outside diameter and comprising an electronic assembly and a bearing to which said electronic assembly is fixed; said electronic module comprising a housing defined by a top face, a bottom face and at least three lateral faces, electronic components disposed in said housing and power connections on which are mounted said electronic components, said electronic module comprising one arm of a bridge rectifier/inverter, said arm being formed by power electronic components of said electronic components and being intended to cooperate with a corresponding phase winding of said machine; said electronic module adapted to form part of said electronic assembly, said electronic assembly forming a complete bridge rectifier/inverter and comprising at least one said electronic module per phase winding of said machine, a dissipator, a power interconnection piece and a signal interconnection piece which are assembled together to form said electronic assembly; and said electronic modules, said power interconnection piece, said signal interconnection piece and said dissipator being placed in different respective parallel planes in said rotary electrical machine; wherein said electronic module comprises: ends of said power connections which are all disposed outside said housing, on a first lateral face of said housing, said first lateral face being intended to be placed by said outside diameter of said rotary electrical machine; signal connection elements intended to transmit control signals for the functioning of said machine, said signal connection elements being placed by one said lateral face which is different from said first lateral face; and positioning and assembling means intended to allow a mechanical assembly of said electronic module with other said electronic modules, said power and signal interconnection pieces and said dissipator in order to form said electronic assembly.
