The DENSO difference
World-leading technologies
Advanced design. OE quality manufacture. Powerful performance.
These are the exceptional standards behind DENSO’s replacement
Starters and Alternators – bringing world class rotating machines
technology direct to the aftermarket.
One of the world’s largest automotive component suppliers, DENSO
is a global leader in developing and manufacturing rotating
machines. Our unwavering commitment to outstanding quality,
design and innovation mean that our Starters and Alternators are
selected as original equipment by carmakers worldwide – winning
many supplier and international quality awards along the way.
Founded on this expertise, DENSO’s programme of replacement
Starters and Alternators offers OE specification, completely new
parts, with no remanufactured units. Every machine is subjected to
our rigorous manufacturing and testing processes, so you can be
sure they meet the highest standards of fit and performance. As well
as delivering unique, OE coverage of Toyota and a wide range of
European marques such as Ford, Opel, BMW, Fiat and Land Rover,
the programme is continually being updated and expanding – and is
planned to cover more than 900 applications by 2012.

DENSO Starters
Since introducing its first commercial automotive Starters in the early
1960s, DENSO has poured its world-leading engineering expertise
into developing smaller, lighter units that can maintain the highest
possible output. In 2001, for example, DENSO introduced the
world’s first Planetary Reduction Segment Conductor Motor (PS)
Starter featuring a square conductor in the armature coil. The PS
starter was 22 percent lighter and 14 percent shorter than the
Reduction A type (RA) Starter, delivering improved fuel efficiency and
an easier fit.
Today, DENSO offers two, advanced types of Starter for aftermarket
customers:
RA-Starter
> High-speed motor with an improved deceleration ratio and a heatresistant
electric wire reduces the size and weight of the motor
> Cold-forged spline reduces the size and weight of the magnetic
switch
PS-Starter
> A rectangular conductor and surface commutator in the armature,
together with a magnet between the main electrodes of the yoke,
reduces the size and weight of the starter
> The damper unit combined with a high deceleration ratio further
reduces starter size and reduces driving noise
DENSO Alternators
DENSO introduced its first automotive Alternators in the 1960s.
Since then we 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, we were able to make the SC
Alternator 20 percent lighter and achieve 50 percent higher output
than a conventional type.
Today, DENSO offers two, advanced types of Alternator for
aftermarket customers:
DENSO
1st
Alternator with Small Internal Fan
> Optimised stator and rotor sizes improve the magnetic circuit to
increase output
> Smaller pulley diameter allows a faster rotor
> Fan features two blades, integrated with the rotor, to reduce fan
noise, size and weight
SC Alternator
> The world’s first rectangular conductor in the stator coil increases
winding density, reduces weight and increases output
> One chip IC regulator
