Problems solved by technology

[0008] However, in some embodiments of such systems, as pointed out in International Patent Application WO2005 / 024202, it may be difficult to connect the electric motor phase inputs to the power supply due to the fact that these inputs are often close to the axis and also due to the Tight constraints between parts and power parts

Embodiment Construction

[0036] Within the scope of the development of the electric booster, the inventors have ensured an electrical connection between the phase input 1 of the electric motor 2 and the connection part 3 of the power circuit board 4 .

[0037] The stator in this particular exemplary embodiment of the machine 2 has a first diameter of approximately 40 mm and the power circuit board 4 has a second diameter of approximately 110 mm.

[0038] Accordingly, the first prongs 1 corresponding to these phase inputs are arranged at predetermined angular intervals around the axis on the carrier of the motor 2 at a first predetermined distance D1 from said axis, at most equal to 20 mm.

[0039] as in figure 1 As clearly shown in , these first pins 1 then enter the connecting portion 3 in the middle of the power supply circuit board 4 .

[0040] The presence of these connecting parts 3 at this location limits the possibilities of the arrangement of the electronic components 5 and their wiring, maki...

Abstract

A connection device is provided for a rotary electric machine of the type supplied with power by a plurality of first pins arranged on a bearing of an axis of the machine at predetermined angular intervals around the axis at a first predetermined distance. The connection device includes a plurality of second pins that are arranged around the axis at a second predetermined distance, which is greater than the first predetermined distance, and that are electrically connected to a plurality of first terminals able to be connected to the first pins. The connection device also includes a main part made of plastics material with a plurality of overmoulded metal bars connecting the second pins and the first terminals.

Description

technical field [0001] The invention relates to a connection device for a rotating electrical machine used in the automotive field, in particular an electric motor for an electric supercharger. [0002] The invention also relates to an electric booster comprising the connection device. Background technique [0003] Ecological considerations and especially the fight against global warming by reducing CO2 emissions have led equipment manufacturers to offer car manufacturers electric superchargers that improve the dynamic response of small low-speed internal combustion engines. [0004] Compared to conventional exhaust-driven superchargers, electric superchargers, that is to say driven by electric motors, have instantaneous response times and improve engine torque at low speeds and under acceleration. [0005] This system makes it possible to significantly reduce the size of the heat engine and thus reduce fuel consumption. [0006] In the case of diesel engines, the latency ...
