At EEMSCO, INC. we believe that electrical testing is at the core of reliability and data driven decision making. It also validates that our work was done correctly. While it’s true that you can’t test in quality, you can’t ensure quality without proper testing. As a service center it is our responsibility to know which tests need to be performed when, what test values are to be used and what is the acceptance criteria. There isn’t a one size fits all for electrical testing of rotating equipment.

National Electrical Manufacturers Association (NEMA), IEC (International Electrotechnical Commission), IEEE and EASA to name a few set guidelines for the tests that need to be performed and when. It’s up to the service center to understand these tests and apply them correctly throughout the repair/rewind process. It’s so much more than random wound, inverter duty, form coil, medium voltage, high voltage and DC. All of this information has the possibility of creating human error traps.

We partnered with Electrom Instruments, Inc. to find a way to eliminate the possibility of these error traps. In partnership we were able to develop test configurations that give test values and acceptance criteria for each step of the repair/rewind process for every winding type we encounter with the use of our iTIG IV+. These configurations give us the ability to provide a clear and concise tasks for the employees. It eliminates confusion, frustration and anxiety for the employee. It provides data and confidence to our customers that their asset was properly tested in EVERY step of the process as required.

Each motor has a unique electrical signature. We gather that unique signature throughout the repair process and again after the motor has been assembled and store it. If needed we can take our iTIG IV+ on site to perform tests to compare as left to as installed signatures for troubleshooting purposes or documentation purposes. ... See MoreSee Less

It’s not often that you see a DC armature with 5 commutator bars per slot. This 5 HP DC motor, may not be big, but it’s mighty. It can produce over 400% of its rated torque.

This motor will get double processed in our epoxy VPI resin for the harsh environment it’s in. At EEMSCO, INC. we’re ready for projects big or small! ... See MoreSee Less

Any time you walk through a service center it’s very easy to find works of art.

At EEMSCO, INC. we’ve been curating our insulation system for years. We follow a UL listed system, but we do a few things ourselves to improve upon it. Our biggest improvements are how we process the windings, how stable we keep our resin and when/how we test windings during the refurbishment process.

We do this by sending in resin samples very regularly and making curated and frequent additions to our resin tank to ensure critical attributes of the resin stay consistent and within a very tight tolerance. Our coil partner Precision Coil & Rotorand resin OEM Star Technology Casey Zimmerman are critical to our success. This gives us a very consistent product everytime.

Here’s a result of all that extra time and effort on a 2.3kV motor. This winding truly is a piece of art, however it’s ready to be placed into service where it’ll be put to the test. This motor will just perform day in and day out. Our measure for success - when we refurbish a motor and it goes in service and performs so well our customer forgets that it’s even there.

Great job team!!!
