DENSO Develops New Alternator for F1
Toyota's new F1 car, "TF105," to use the alternator
TOKYO - - DENSO Corporation today announced that it has developed a new alternator for Formula 1 (F1) racing. This alternator will be installed in the new "TF105" F1 race car of the Panasonic Toyota Racing F1 Team this season.
The alternator generates alternating currents at the stator coil when the rotor is turned by the engine.
"We significantly reduced the size of the rotor as well as the stator by adopting a new magnetic structure for the rotor and a new cooling structure for the rotor and stator," said Mineo Hanai, managing officer of DENSO Corporation in charge of the Electric Systems Business Group. "That allowed us to reduce the overall size and weight of the alternator."
DENSO is supplying small, light, and efficient alternators for a variety of vehicles including passenger cars, motorcars and trucks. In this product field, DENSO has captured the world number one market share since 1988.
DENSO joined the Panasonic Toyota Racing F1 Team as a corporate sponsor in 2004. Several DENSO products including spark plug, radiator and oil cooler were used in last season's Toyota F1 car, the "TF104."

Its customers include all the world's major carmakers. Worldwide, the company employs 95,000 people in 31 countries and regions, including Japan.
