A customer of EEMSCO, INC. was picking up ball spin frequency during a vibration analysis. They removed this critical 800HP, 2.3kV compressor motor before it got worse and reconditioned the motor on a rush basis. Dissecting the bearings we confirmed ball spin by looking at the rolling elements and races.

By proactively pulling this motor, they were able to save significantly on rental fees, unplanned downtime and lower repair costs as only superficial mechanical work was required to return this motor back into service, outside of our standard reconditioning.

Well done everyone!

There are many advantages to planned outage work, especially from a cost savings perspective. This 300kW motor was pulled from service and reinstalled and aligned 4 days later after a complete evaluation and recondition at our facility. The EEMSCO, INC. team provided a turn key solution on this project. Many parts for the recondition were preordered to save on costs and ensured product availability months in advance.

There was a significant cost savings for not having to expedite parts, and ensuring that they were in stock waiting at our facility. This has become a common practice with this particular customer. Short deadlines around holidays during their shutdown. They all go smoothly due to all the upfront work completed months in advance.

Many planners do not receive the recognition they deserve for proper planning. When things run smoothly, it’s just another day in the office. We recognize and appreciate this effort. For all the planners out there, thank you for your efforts to streamline work scopes and all the upfront planning you do day in and day out.

Here’s a few pictures before the motor was completely reassembled and delivered to the customer for alignment & installation. Final electrical tests and QA were to be performed before installing other covers and shrouds.

Thank you team for all your hard work and dedication on this project! ... See MoreSee Less

The insulation system on certain motor components can be complex. The service center needs to understand what materials are best when. Especially, if we are working with customers to make something better or solve a problem. Here’s a picture of a 700HP DC motor’s interpoles that we reinsulated and processed in house. Insulating materials were carefully picked to ensure proper dielectric strength and heat transfer. To remove any potential air voids which can trap heat, the interpoles were VPI’ed in our epoxy resin from STAR Technology, Inc. and potted with a potting compound which has better heat transfer properties than normal. The end result: They look great, have minimal leakage current, have the ability to transfer heat away from the coil and have a protective coating that will allow them to be in service for many years in harsh environments. Well done team! ... See MoreSee Less

In the electromechanical repair service industry there are several key pieces of equipment that are needed to ensure a electric machine is restored to “as new” conditions. “As new” doesn’t just mean new windings and a new paint job. As an EASA accredited service center we have many QA checkpoints throughout the refurbishment process. One such area is having a burn out oven that has temperature control, chart recording and a few other key attributes to protect the equipment being burned out and employees.

The integrity of the core laminations must not have more than a 20% change in Watts/lb losses pre and post burn to maintain efficiency. If core laminations are burned at too high of a temperature damage can occur to the coating on the lamination steel amongst other things which negatively effect the cores integrity and overall machine efficiency. Maintaining proper core temperature during the burn out process can help achieve that goal.

We partnered with ECO Burn-Off Ovens for this critical step in the refurbishment process. Why? Maintaining part temperature, safety and proper after burner control is crucial for our employees, customers and the environment. They check every box for this. More to come on what this process looks like.
