Denso Completes Integration with ASMO in the U.S. to Strengthen Motors Business &
Technology
Denso, the world's
second largest mobility supplier and a
major developer of
advanced
permanent magnet motor
technology, has fully
integrated its consolidated subsidiary
ASMO companies in
the U.S. into its North
American
operations. By combining
ASMO's small-motor
strengths with Denso's expertise in large, high-power motors, the
company aims to accelerate its development of motor innovations
for North American customers.
The company formerly known as ASMO North Carolina, Inc., will
become a more integral part of Denso's North America Motors
Business group. DMNC's main site is in Statesville, NC, with additional locations in Greenville, NC; Battle Creek, MI; and Ennis,
TX. The change is part of Denso's long-term plan to operate more
efficiently while accelerating research and development.
"Automakers around the world are focused on electrification and
automated driving. The products and technologies required to
support that are sophisticated and require constant innovation
and enhancements," said Kenichiro Ito, executive officer for Denso and chief executive officer of the company's North American
headquarters. "This business integration will allow us to combine
the strengths of both companies." New electrified automotive
systems require high-precision and high-value-added motors, he
noted.

formance of electric vehicles and fuel efficiency of hybrid vehicles.
Denso developed its motor generator using proprietary winding
technology and rectangular magnet wire that is enhanced by its
flagship SC (segment conductor) alternators. The developed coil
end shape, winding structure, and manufacturing method have
contributed to size and weight reduction, easy installation, drivetime power reduction and increased fuel efficiency.

Rectangular coil wire

The coil space factor in the iron core has been improved by more
than 10% by using wires with a rectangular instead of circular
cross section. Also, the overlap at the coil end has been reduced
to decrease the electrical resistance. This helps decrease the heat
generated when large currents flow, achieving driving efficiency
and power generation with less environmental impact.

Masanori Iyama will serve as president of DMNC, transitioning
from his previous role as head of Denso's Motor Planning Division. DMNC produces blower motors, power seat motors, windshield wiper systems, power window motors, electric power steering motors and pinch sensor assemblies. It employs roughly 1,500
people.
Part of the company's long-term plan, announced in 2017, was to
make one person the lead in R&D in North America and Europe
to promote collaboration in advanced technology. Another was to
set up satellite R&D facilities globally to execute advanced R&D
more speedily.
With manufacturing at its core and a robust R&D commitment,
Denso is a $48 billion enterprise headquartered in Kariya, Japan
with 221 facilities in 35 countries that produce thermal, powertrain,
mobility, electrification, & electronic systems. The company employs 170,000 people and in its most recent fiscal year spent
9.3% of revenues on R&D. Its North American operations include
27,000 engineers, researchers and skilled workers across 31 sites
in the U.S, Canada and Mexico.
One of its core technologies is the design and manufacture of motor generators which play a key role in improving the dynamic per-

Distributed winding

By using a distributed winding design in which coils are wound in the
same width as the permanent magnets in the rotor, Denso takes full
advantage of the magnets' magnetic flux to generate electricity. To reduce the coil overlap, the company developed a proprietary manufacturing technology to align and assemble each u-shaped coil element,
enabling mass production with high quality.
