James P. Muccioli received his bachelor's and master's degrees in electrical engineering
from the University of Michigan. He has extensive experience in EMC design, analysis,
and testing. His background includes over twenty years of specialized EMC systems
experience at X2Y Attenuators, DaimlerChrysler and United Technologies. Mr. Muccioli
co‐authored articles published in the IEEE Transactions on Electromagnetic
Compatibility (The Electromagnetic Environment of an Automobile Electronic System;
August, 1987), the 1990 IEEE International Symposium on Electromagnetic
Compatibility (Radiated Emissions of Very Large Scale Integrated Circuits),
Circuits) and the 1991
IEEE International Symposium on Electromagnetic Compatibility (An Electromagnetic
Immunity Diagnostic Tool for Electronic Circuits). He published several articles on
integrated circuit emissions in EMC Test & Design Magazine (1992‐1993). He was a
contributing author (Part 6 Electromagnetic Interference and Compatibility) for the
Automotive Electronics Handbook ((Ronald JJurgen,
g , Editor‐in Chief,, McGraw‐Hill,, Inc.,,
Mr. Muccioli taught an undergraduate course ("Noise Reduction
Techniques") and a continuing education seminar ("Electronic System Noise
Reduction") at Lawrence Technological University and the University of Michigan. He
presented a paper (Integrated Circuit Decoupling ‐ A Key Automotive EMI Concern) at
the EMC/ESD International 1992. Mr. Muccioli is a certified EMC engineer through the
Nationall Association off Radio
d and
d Telecommunications
Engineers. He is an active
member of SAE J‐1113 and J‐551 EMC committees and is chairman of the SAE Integrated
Circuit EMC Task Force. He is a member of the Board of Directors of the IEEE EMC
Society (1993‐1998; 2001‐2003) and was selected as an IEEE Fellow in 1998 for
contributions to integrated circuit design practices to minimize electromagnetic

Terry M. North
Terry M.
M North received both BSEE and MSEE degrees
from Wayne State University. His early experience
includes service with the U. S. Army in RF
communications and with Ford Motor Company in
advanced fuel systems design. Joining Chrysler in 1985, Mr.
North was one of the early contributors in the effort to

automotive focus. Over the more than 20 years that he was
with Chrysler, he contributed to the development of a
world class in house automotive EMC capability, which
assisted in the advancement of the automotive industry in
EMC. Mr. North was also involved in the EMC
d l
d qualification

off passive
systems at Chrysler. He was a major contributor in the
development of Chrysler corporate EMC standards and
served as a consultant on EMC and E/E systems issues. As
a Senior Engineering Specialist with DaimlerChrysler, he
also contributed to the development of international EMC
standards that combined different backgrounds and
processes. He is a member of the SAE EMC Committee and
its Integrated Circuits EMC Task Force and is the co‐
author of the SAE J1752 series of standards. Mr. North has
three patents for EMC test development and has co‐
on IC RF Emissions and EMC test
written several p
development that were presented at IEEE Symposiums.
Mr. North has more than 20 years of experience in EMC
and is a senior member of the IEEE.

Typical approach to EMC – it is ignored until problems occur.
y EMC is NOT a vehicle functionality problem – component/module y
designers don’t realize impact of functionality on vehicle.
EMC is seen as a test requirement not a hardware design criteria.
EMC Test Labs have the expertise to fix DC motors that fail requirements.
EMC compliance is seen as a cost and packaging burden.
Many electro‐mechanical system designers lack basic EMC concepts.
y Most consumer & automotive motors have historically filtered the AM & FM radio bands for long duration motors only.
y Research initiatives y Assume next generation technologies and/or software eliminates need for basic EMC engineering.
y Ignore EMC issues and assume they will be addressed at production.

y DC motors are a broad brand frequency noise source from kH GH kHz to GHz. y Mil Std 461E has requirements from 10kHz to 10GHz.
y Brush commutated motors can be looked at as high frequency spark gap between the brushes and commentator.
h b h
y Electrically commutated (Brushless) motors have FETs with switching times that contain broad frequency content.
y Increased vehicle electronics and communication devices have increased operating frequency bands in vehicles.
y Motor EMI suppression lowers ambient noise of the vehicle thus increasing signal‐to‐noise ratio thresholds for other on‐vehicle electronics.
