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.
Well done team!

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.
Great job team!

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.
Great job team!!
