BorgWarner Emissions Systems has developed a new
compact brushless actuator designed to optimize engine
performance and reduce NOx emissions from on- and off-
road commercial diesel engines.

Borg Warner’s new second-generation compact brushless
actuator designed to deliver more capability in a smaller package
BorgWarner Emissions Sys- tems, a global supplier of air management and emissions control products for commercial
vehicles, light trucks and passenger
cars, has developed a new compact
brushless actuator designed to optimize engine performance and reduce
NOx emissions from on- and off-road
commercial diesel engines. The new
actuator, which the company said is
significantly more compact than conventional actuators, utilizes patented
“smart” electronics to precisely control complex engine emissions- and
performance-related components,
such as turbochargers and exhaust
gas recirculation (EGR) valves.
“With electric actuation, smart
electronics and proven reliability,
Borg Warner’s compact brushless actu-
ator delivers higher operating torque,
faster response and better durability all
in a smaller package,” said Dr. Thomas
Waldhier, president and general man-
ager, Borg Warner Emissions Systems.
“Our new compact brushless actuator
combines several advancements in a
reliable, compact design.”
The actuator is a second-generation
technology that produces peak torque
outputs comparable to the earlier ver-
sions but in a package 20% smaller,
Borg Warner said. The unit can deliver
a torque of 4. 4 lb.ft. in a physical enve-
lope of 5. 27 x 3. 38 x 3. 89 in.
One of the keys to that capability is
an optimized brushless dc motor drive
and advanced heavy-duty geartrain that
the company said incorporates highly
engineered composite materials. Built
to maximize both impact strength and
high-cycling capability, it is designed
to accommodate the rigorous impact
requirements necessary for seating
against a valve as well as power-on
learning events, while maintaining the
enhanced durability of previous generation products, the company said. The
unit can withstand temperatures up to
284°F and provides continuous operation up to 266°F. For even higher temperature capability, two water-cooling
options are available.
