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:
