The alternator (& regulator) is driven by the engine via the belt. It converts mechanical energy into electrical energy, and supplies the required power to the various electrical loads. When power supplied by the alternator does not match the required electrical load (when all the electrical equipment is in use, or when the engine speed is low during idling etc.), the battery temporarily supplies extra power to the electrical equipment. However, during normal driving the alternator re-charges the battery to the original strength.

The engine speed changes constantly according to the driving conditions. This means that the alternator speed also changes, with the generated voltage changing in tandem. It is the role of the regulator to control the generated voltage of the alternator, supplying the various electrical loads with the appropriate voltage. The regulator also makes sure that the battery is charged appropriately.

DENSO introduced its first automotive Alternators in the 1960s. Since then they have pioneered a variety of new alternator designs capable of producing more electrical power more efficiently, yet in a smaller, lighter unit. In 2000, for example, 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, they were able to make the SC Alternator 20 percent lighter and achieve 50 percent higher output than a conventional type.

DENSO First Time Fit® parts meet or exceed all manufacturer standards, mount properly with a minimum of installation issues, and provide years of reliable service.
