The invention relates to a rotary electric machine, in particular for a motor vehicle, including: a stator () comprising a stator body () and an electrical coil, said electrical coil including a plurality of phase windings () forming a bundle () that protrudes from an axial end face of the stator body, each phase winding including an end forming a coil connection point (); and at least one electrical connection member () positioned in continuation of the stator () and comprising at least one electrically conductive element () which is overmolded with an electrically insulating material () and extends radially out of the electrically insulating material to form at least two connection outputs () to which the connection points are connected.

Rotary electrical machine

A rotating electrical machine for a motor vehicle comprising a rotor () supplied with an excitation current (ie), a stator () comprising a polyphase winding and coupled to the rotor (), a thermal protection module () suitable for evaluating at least one temperature (T, T, T) in the machine and for comparing the temperature with an associated thermal protection threshold (Th), a control device () supplying the excitation current (ie) depending on an operation mode command (RQ) and the temperature comparison, so as to operate the rotating electrical machine () according to a mode of operation chosen from a nominal generator mode in which the machine is configured to deliver a first maximum power or at least one extended generator mode in which the machine is configured to deliver a second maximum power greater than said first maximum power.

Rotating electric machine for a motor vehicle

The method according to the invention calls upon a rotary electric machine () comprising a drive member () and a transmission member () of the belt or chain type, collaborating with the drive member and with the combustion engine () in order to start or restart the combustion engine, a tensioner () being provided to press against one strand () of the transmission member that extends between the rotary electric machine and the combustion engine. According to the invention, in a first stage, the rotary electric machine () supplies a predetermined reduced torque in the direction of starting for a predetermined duration in order to tension the transmission member () and then, in a second stage, the rotary electric machine () supplies a predetermined optimum torque for rapidly turning over the combustion engine () and causing it to start.

Method and device for starting or restarting thermal engine

The method according to the invention is implemented in an alternator-starter () comprising phase windings (u,v,w) connected to an inverter () linked to an onboard electrical network () powered by a battery for operation as a starter. The invention involves controlling the inverter in a chopped full-wave control mode when the rotational speed (&#x3a9;) of the alternator-starter is lower than at least a threshold speed and in a full-wave control mode when the rotational speed is higher than the threshold speed. According to a specific embodiment, the switching between the chopped full-wave control mode and the full-wave control mode takes place according to a hysteresis cycle using two predefined threshold speeds.
