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.,,
1995,1999).
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
l
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
interference.

Typical approach to EMC – it is ignored until problems occur.

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 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.
