ISG Assembly for 2-Wheelers

The document describes an integrated starter generator assembly (ISG) that features smooth starting capability and battery-less operation using standard grade ferrite magnets. Key specifications of the ISG include a rotor outer diameter of 114mm, length of 54mm, stator weight of 1.2kg, and rotor weight of 0.9kg. The ISG can generate 14V DC at 10 amps at 2000 rpm and is capable of battery charging starting at 1200 rpm. An ISG controller is also described that uses field-oriented control techniques to maximize torque during starting and regulates the alternator output voltage. The controller supports idle stop functionality to improve fuel efficiency.

ISG Controller
Integrated Starter Generator is the technology which integrates the Starter and Generator functionality
together. ISG Controller is designed to control Starter and Generator functionality for 2 wheeler
application. During the starting it uses FOC drive techniques to maximize the torque and provide
smooth starting. In Generator Mode it regulates the ACG output at 14.3VDC to drive the vehicle load
and to charge the battery. The advantage of this ISG Controller unit is to improve the fuel efficiency by
idle stop, weight reduction by starter motor deletion, quiet engine start-up, long life due to the
brushless motor and Communication between
ignition ECU and ISG ECU via CAN.
