VS - Electrical Systems From Stop-Start to Hybridization

The i-StARS machine Contrary to the very first StARS machines, the i-StARS embeds inside the body of the machine all control and power electronics required to manage the starting, the charging mode and new features. ●● No more power cable ●● No more external power controller i-StARS development was a real technical challenge knowing all physical constraints that need to withstand underhood products, particularly when fitted onto the engine body.

The i-StARS machine is composed of: ●● A rotor ●● A stator ●● A control frame with several micro electronics modules for control and power ●● A rotor angular position sensor ●● Two connectives systems, one for 12v battery cable and one for control signals ●● A brush holder ●● A heat sink

●● A fan system ●● Ball bearings ●● Housing and brackets ●● A poly-V pulley

MOS transistors are combined to built up half-bridges modules, with one power module per phase
