In recent years, vehicle power consumption has increased with the emergence of information and communication products such as navigation systems, and electronic control products to improve comfort and safety and make vehicles environmentally friendly. To meet the demand for additional power, alternators must produce electric power more efficiently with smaller size and lighter weight. DENSO has been developing a variety of alternators that meet those requirements for a variety of vehicles including passenger cars, motorcycles, and large trucks.

DENSO Technology - Leading the World
In 2000, DENSO introduced the world's first SC (Segment Conductor) alternator using a rectangular conductor for its stator coil. By raising the winding density (space factor) from 45 percent to 70 percent, DENSO made the SC alternator 20 percent lighter and increased the output 50 percent higher than a conventional type.
