Case Study of Filtered Connector Application in Blower Motor to Meet EMC Requirements

July 3, 2006 PAGE 2©X2Y Attenuators, LLC

Prototype Test Goals

Design and implement filtered connector with X2Y® Technology on a blower motor that can meet or exceed EMC requirements set forth by automobile manufacturers:• 2005 SAE World Congress paper:

Electromagnetic Compatibility of Direct Current Motors in an Automobile Environment “

Measure differences in modifications to connector.Verify X2Y performance vs. conventional EMI filtering.

Testing Presented Within this Document

Data was taken by X2Y Attenuators, LLC at the Detroit facility. The measured radiated and conducted emissions data is used for A to B comparisons of filter effectiveness. Although the data is not validated to specific test requirements at an approved test facility, products that meet performance benchmarks established in X2Y’s test chamber typically result in approvals at certified test facilities.


Test Set-up

Radiated Emissions Test Set-up


RE Test Set-upThe DUT was placed in an ETS-Lindgren IC-GTEM 250 along with a 12 V power source connected by a 3 meter harness.

Note: the harness is wrapped between wooden pins on a wooden platform for repeatability of measurements. Note: DUT is tested under load conditions.


RE Test Set-up (continued)

An IFR AN920 spectrum analyzer was used to measure and record RE.The spectrum analyzer settings are:• Frequency spectrum = 100 kHz – 1000 MHz• Bandwidth = 120 kHz• Sampling = 3 Peak Hold

Conducted Emissions Test Set-up


CE Test Set-up

The DUT was placed in a shield box measuring approx 29 by 18 inches.Between the DUT and 12 V power source are (2) LISNsType 6338-5-TS-50N. (manufactured by solar Electronics Co.)There is approx 8 inches of harness between power supply & LISN and LISN & DUT.Note: DUT is tested under load conditions.

CE Test Set-up (continued)

Again, an IFR AN920 spectrum analyzer was used to measure and record CE.Measurements were taken in (2) different frequency spectrums.• Spectrum analyzer settings #1:

Frequency spectrum = 150 kHz – 30 MHzBandwidth = 9 kHzSampling = 3 Peak Hold

• Spectrum analyzer settings #2:Frequency spectrum = 30 MHz – 200 MHzBandwidth = 120 kHzSampling = 3 Peak Hold

Connector Design IssuesDetermining the ground layout of the connector face is critical.(Connector supplied by ITT Industries/Cannon.)• Bottom only GND• Top & Bottom GND

Note: solder connection preferred, press fit will lose RF performance. • Top & Bottom GND with (–) power lead attached to GND

Note: solder connection preferred, press fit will lose RF performance.

Connector Implementation Issues

Determining the ground interface of the connector and motor housing is critical.A good RF GND would require multiple connector & motor housing contacts at several points.

Note: Conductive tape was used to make GND connection to top of connector during testing.
