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.

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.

Often in our posts, we use the term “trusted partner.”We have some customers who work side by side with us to solve problems to make their plant more reliable. Their staff comes and works with our staff to find failures and develop solutions. In one case, we had a customer who had continuous bearing failures on a certain style of shaker motor. They would last anywhere from 6 to 11 months at best. These were fairly large shaker motors at 4kW and had 2319 roller bearings in each end. Through several conversations and a defined plan, we’ve been able to more than double the bearing life of the shaker motor, through a bearing style change and updated PM schedule. One motor was taken out of service to check performance at 23 months and it was doing just fine after an inspection.
EEMSCO, INC. was on site helping a customer determine if their 500HP motor had failed or if it was somewhere else in the power circuit. Electrom Instruments, Inc. iTIG IV+ and PdMA Corporation MCEMAX are great tools to help you properly diagnose motor driven system electrical faults.
This customer did the right thing. Once the drive tripped for a ground fault on start-up after being down for cleaning, they didn’t try it again. It makes troubleshooting and maybe even saves costs on equipment repairs and future unplanned downtime.
Here’s a couple pictures of a 150HP/37.5HP, 2 speed 2 winding motor EEMSCO, INC.
These windings can be difficult to get to lay in correctly with proper insulation between the phases and windings. The use of phase paper which absorbs resin not only provides great mechanical strength, it also provides superior dielectric strength as well.
Here is a 40HP P&H wound rotor induction motor (WRIM) that needed some TLC. The stator and wound rotor needed to be rewound, the shaft needed to be replaced a new brake drum was needed and a several other things.
We were able to refurbish this WRIM, manufacture a new shaft and provide some winding insulation system upgrades for the stator and rotor. Our customer was able to capitalize on a large cost savings and reduction in lead time. The figures for our offering was 36% of the cost of a new machine in 31% of the lead time. The new insulation system will provide theoretically twice the life from a thermal degradation perspective and the epoxy resin and process we use is specifically made for harsh environments. It’s not as good as new, its better than new!
Finishing up a 350HP 2.3kV motor for a customer. This motor was rewound an insulation system which meets the 3.5 pu impulse criteria, class H materials, magnetic wedges and double processed in our epoxy varnish for harsh environments.
Rotor was balanced to ISO G1.0 standards. Motor was tested with PdMA Corporation and Electrom Instruments, Inc. ITIG IV with pd capabilities, test ran and vibration analysis conducted.
