Integrated Starter Generator (ISG) ECU
Integrated Starter Generator (ISG) is a technology that eliminates the need for conventional starter-motor based engine start systems. ISG results in instant and smooth engine start, improved reliability and also enables idle stop-start feature.
SEDEMAC offers ISG ECUs for small engines with crankshaft mounted alternators (like used in two-wheelers). The forward looking ECU architecture design enables integration of electronics of other control intensive technologies such as Electronic Fuel Injection (EFI) & Automated Manual Transmission (AMT). It integrates engine starting, battery charging and ignition control resulting in a centralised and intelligent control of overall engine / vehicle operation.
ISG has several advantages, such as:
ISG eliminates all components of the starter motor system as well as the ignition controller and battery charging controller. Typically the following parts are eliminated: starter motor, starter-motor-associated one-way clutch / gearing, starter relay, ignition CDI / TCI, VRR (voltage regulator). These parts are replaced by a single part -- SEDEMAC's ISG ECU.
SEDEMAC's ISG solution offers a sensorless electric machine architecture. More specifically, no hall sensors are used / required. This unique patent-pending technology provides significant benefits of:
