Motor Generator

Motor Generator (MG) is the integrated unit of engine starting function as starter and electric power output function as alternator.MG realizes various technology such as idle-stop, engine assist whentravelling, and regeneration during deceleration etc.

• Improvement of vehicle installation ability with integration of electro-mechanical structure both GX alternator technologies and power electronics technologies.

• Quiet start with belt-drive• Quick re-start and high engine speed assist with unique control

technologies.• High efficiency generation and low noise with unique stator coil

winding technologies.
