Direct Drive iSG
Our Development Aim

A model and stator prototype on display at the Tokyo Motor Show 2017
As part of our company's electric technology, we are independently developing an iSG (integrated Starter Generator) that directly drives the engine without using a belt.
Generally, starter generators used for power generation and driving installed in commercial vehicles, are belt-driven. However, our company's "Direct Drive iSG" is a starter generator installed around the torque converter or clutch, and therefore connects directly to the engine without the use of a belt.
With this product we aim to improve fuel economy by reducing friction loss, achieve a cost reduction and save space by integrating and eliminating parts.
