A dissipator for electronic components, the electronic components being intended for the functioning of a rotary electrical machine, the machine comprising a rear bearing, the dissipator comprising a top face and a bottom face including fins. The present invention applies to any type of polyphase rotary electrical machine, synchronous or asynchronous, such as alternators or alternator starters, and also whether it is a case of electrical machines for motor vehicles and driven for example by belt, with cooling by air, liquid or any other solution that can be envisaged.

Signal interconnecting part for electrical rotating machine

A power interconnection piece for a rotary electrical machine, wherein the power interconnection piece comprises at least one power track provided with electrical power terminals intended to cooperate with a power track of at least one electronic module so as to distribute electrical power to the electronic module, the electronic module being integrated on the rotary electrical machine and wherein the power interconnection piece comprises a base plate made from insulating material that at least partially overmolds the power track.

An electronic module for a rotary electrical machine which applies to any type of polyphase rotary electrical machine, synchronous or asynchronous, such as alternators or alternator starters, and also whether it is a case of electrical machines for motor vehicles and driven for example by belt, with cooling by air, liquid or any other solution that can be envisaged.

Electronic module for rotating electrical machine

An assembly of electronic components for a rotary electrical machine and power and signal interconnection pieces cooperating with the electronic components in order respectively to distribute power to the electronic components and convey control signals between electronic components for the functioning of the rotary electrical machine, wherein the electronic components are disposed in at least one module disposed on a first plane, the at least one module comprising a housing defined by a top face and a bottom face and at least three lateral faces, the signal interconnection piece is disposed on a second plane parallel to the first plane, and the power interconnection piece is disposed on a third plane parallel to the first plane, the power and signal interconnection pieces being independent of each other and independent of the at least one module.

Assembly of electronic components for electrical rotating machine

A dissipator for discharging heat from electronic components, the electronic components being intended for the functioning of a rotary electrical machine, the rotary electrical machine comprising a rear bearing, the dissipator comprising a top face and a bottom face integrating fins, wherein the dissipator is disposed between the rear bearing of the rotary electric machine and the electronic components, the bottom face integrating the fins coming opposite the rear bearing when the dissipator is disposed between the rear bearing of the rotary electrical machine and the electronic components.

Heat sink for electronic components of a rotating electric machine

This electronic module comprises a metallic base () and electronic power components (D, D, D, D, D, D) on the base; in which each component, in a group consisting of some of the components, is mounted on the base with a respective electrically insulating and thermally conductive element () being interposed, the other components of the power module being connected electrically to the said base, and in which a peripheral frame () is mounted on the base and incorporates interconnecting elements of electrically conductive materials. The invention is applicable in the field of motor vehicle alternators.
