EMI Consulting Services
LCR sincerely believes that a well informed customer is an important asset to
our successful business. We feel that our customers should be knowledgeable about
the Electromagnetic Compliance (EMC) process.
To achieve this, LCR offers EMC training and consulting to enable customers to
adopt EMI friendly design practices for economical, hassle-free EMC.
LCR keeps up to date with the latest EMC requirements and can guide you through the
compliance process before you get involved in expensive and often unnecessary certification
Helping You Meet the Test!
We offer comprehensive testing services to commercial
standards (FCC, CISPR, EN, VDE, AUSTEL, SABS, etc.), as well as to military and aerospace
standards (MIL-STD-461, RTCA-DO160 and more). LCR has also been helping its customers
achieve compliance with European Union EMC requirements (CE) since their inception.
Custom-Tailored On-Site Training
In addition, LCR can provide your company with EMC training. This training is
arranged at the customer's premises in the form of a seminar so that most of the customer's engineers can attend and receive the benefit of the
We have presented seminars for numerous OEMs and trade associations, and will
gladly help you with your own in-house training or consulting needs. Like our products,
seminars also can be custom tailored to your specific needs and goals.
EMC Testing Services
LCR is dedicated to providing economically viable EMI/RFI
filters and EMC solutions to satisfy our customers' unique needs.
To that end it has two fully equipped shielded chambers where EMC testing, EMI/RFI
filter design and EMC solution development are accomplished.
LCR has experience with military (MIL-STD), aerospace (RTCA/DO160)
as well as commercial (FCC, CISPR, EN, VDE, AUSTEL, SABS, etc) test standards. LCR
has been helping its customers achieve compliance with European Union EMC requirements
(CE) since their inception.
Testing…for Compliance and Solutions
LCR's approach to testing is very different and unique. We don't just
conduct EMC testing for our customer's product — we also provide a practical
and cost-effective EMC solution to bring the product into compliance with relevant
standards or specifications. The EMI/RFI filter solutions are optimized specifically
for the products and provide appropriate safety margins to ensure compliance.
Should there be an EMC non-compliance, LCR analyzes the test results with a view
to understanding the modes of failure in order to design, develop and recommend the
most practical and cost-effective solution.
The EMC solution can sometimes be as simple as changing the brush grade on a universal
motor or re-routing the wire harness or a simple capacitor-resistor combination across
the input. Or it can be a more sophisticated EMI/RFI filter or redesign of the PC
board. We do whatever it takes to get the products to comply and insure that it makes
sense from a cost and long-term manufacturability point of view. And we do it quickly
So Much to Choose From
LCR Electronics has over 18,000 different EMI/RFI filter designs and in many circumstances,
we can tailor these designs to meet the most demanding product requirements without
the need for costly and time consuming efforts.
Not only are our EMC testing engineers highly trained and experienced in EMI/RFI
filter design, but they also have the ability to quickly understand your product,
its design and circuitry which enables them to identify potential EMI sources quickly.
Our numerous customers do repetitive business with us not just because they are
happy and satisfied with our services but also because they feel that we are easy
to do business with!!!
LCR believes that an educated customer is a satisfied customer! Therefore, LCR
offers seminars to groups of engineers on-site at your facility or at our Corporate
Headquarters in Norristown, PA.
Some of the titles of our most recent seminars are:
- Meeting the Challenge: The European Union's EMC Directive
- Designing for EMC Compliance: A Strategic Approach
- Designing for EMC Compliance: A System Approach to Integrated Appliance Controls
- Designing for EMC Compliance: A Design Guide for Appliances & Portable Tools
- The ABC's of EMI in Appliance Design
Should you or your team of engineers have a need to be better educated in designing
products to cost-effectively meet EMC/EMI/RFI compliance regulations, please contact us for more information.
Customized for Optimum Solutions
Seminars can be tailor-made (as we do our for our EMI/RFI
filter solutions) to suit your exact needs. So, if you are finding it too painful
or costly to comply with the European Union EMC Directive (or any other National
or International EMC regulation)...
If you need help in structuring an EMC management system to ensure ongoing EMC compliance
If you or your team need to develop a basic understanding of EMC, EMI and RFI concepts, please contact us for more information.
Here's an outline of one of our recent seminars:
DESIGNING EMC FRIENDLY MOTORS AND ELECTRONIC CONTROLS FOR APPLIANCES - THE SYSTEMS
ABSTRACT: Many appliance designers today approach a new product by considering
the motor needed to meet the torque/speed/performance requirements. Then, an electronic
control is considered and designed to control the motor. Finally, after the product
package is complete, an EMI/RFI filter is added for EMC regulatory compliance or
noise immunity. This approach DOES NOT result in the optimum system cost. A better
approach is to consider the motor, control, and EMC filter concurrently during the
- Determining the torque and speed required
- Dynamic performance (speed regulation, torque transient rejection, etc.)
- Important system parameters (gearing, inertia, damping, etc.)
- Important specifications (line voltage variation, temperature, EMI limits)
- Required diagnostics
- Available cooling is supplied by the unit
- EMI shielding offered by the unit
- Selecting the control for minimum possible current to meet torque/speed
- Selecting a motor to meet that current and EMC constraints
- Determining a cost estimate and iterating on motor, control, and EMI/RFI filter
- Design example: Triac controlled universal motor with hall sensor vs. PM brush
motor with current sensor
ABSTRACT: This is a basic presentation that is given to most companies to educate them in EMI. It is designed for people with no knowledge or limited knowledge of EMI/EMC and can be presented to electrical and mechanical disciplines. It also works great as a refresher for more experienced participants. We find the majority of people still treat EMI/EMC as an unknown and therefore fail to adhere to simple rules during design. This presentation explains the do’s and don’ts for a complaint EMI/EMC design.
