5,000KVA Transformer Failure

An Iron and Metal Recycling Facility, Located in Dayton, Ohio called and had a transformer fail and was asking for help. I contacted Don Morris to asked for his assistance.

The new transformer had a 50 working day [...]

Centrifugal Force – What Is It?

The words “centrifugal force” were first used in the year 1698, so it is far from a new concept. A dictionary definition is “the apparent force that is felt by an object that is moving in a curved path that acts outwardly away from the center of rotation.” We have all felt the effects of centrifugal force when we are driving our car or truck and turn a corner at a high rate of speed. As long as we are moving in a straight line, we do not feel this force but when we exit the highway at a high rate [...]

Keeping a Plane Safe at 35,000 Feet

Aircraft Engines are the beating heart of an airplane. We, as passengers expect them to run free of mechanical errors and keep us safe in the air no matter what happens: bad weather, geese, etc. The manufacturers of these engines test them extensively to make sure they are built well. Horner gets to be involved somewhat in keeping those testing facilities up and running. An aircraft engine manufacturer needed repair and maintenance on a 6,000 HP Compressor Motor. The compressor furnishes air for testing aircraft engines. It is run on a Dynometer which we have also repaired in the past. The [...]

2000 HP Aluminum Plant DC Motors

An Aluminum Rolling and Recycling plant, a good Horner customer in Terre Haute brought Todd Cochran (Sales) a problem/ or opportunity to Indianapolis Field Service. The customer has two, 2,000 HP DC motors coupled together, to deliver 4,000 HP to their mill. These motors are about 5-6 foot square, and 10 feet long each. The inside motor, the one coupled between the mill and the second motor, failed and had to be replaced with a spare. This is not something they can shut down for a couple of days. Of course this happens when the Indianapolis Field Service group is working [...]

Made In Japan, Rebuilt In The US

Everyone is well aware of the quality of Japanese autos in today’s market. In the 1980’s, the Japanese raised the quality bar in the automotive industry, resulting in cars that were of a higher quality and remained in service for many more miles than most of the domestic autos of that time. This off-shore challenge resulted in the upgrade of quality for all American automakers, just to remain in business. This quality concept also applies to the motor repair business and is why our company has Quality Manager like Vernon Pratt, to help us keep quality at the forefront of our [...]

Fermentation Process DC Motors

The Terre Haute shop currently rebuilds and reconditions many DC motors for an Animal Health Products customer. There are 16 600HP Louis Allis motors, 11 600HP GE motors, and 16 500HP Louis Allis motors. These motors are used in the fermentation process. At the customer site the product is produced in a lab setting then sent through the fermentation process until it grows and is completed. It takes about two weeks to complete the finished product. If a motor fails during fermentation, the entire batch will have to be scrapped. So the operation of these motors is critical. They run 24/7 [...]

Aluminum Plant Outage

In June of 2017 an Aluminum plant contacted us to begin the early planning stages of their outage which was scheduled for January 2018. The customer was about to undertake the most involved outage on their primary mill and wanted Horner’s exclusive involvement. The outage was a success despite the very large scale and daunting tasks assigned. All work was coordinated by Ralph Coonce of field service. If you’ve ever seen Ralph in action during an outage I don’t have to explain that he doesn’t just show up. He’s elbow deep in the actual work turning wrenches or any another task [...]

1500 HP Aggregate Mill Motor

A large aggregate company in Southern Indiana that Horner Industrial has serviced for years contacted Horner as they had a 1,500 HP 180 rpm Open Frame AC Wound Rotor/Synchronous motor that needed to be removed, rewound, and reinstalled. This motor was manufactured in the 1950’s and it was one heavy piece of iron. (42,000lbs) Once it was removed, transporting it posed a challenge to Horner’s Logistics Department as it had to be transported on a special “low-boy” semi-trailer due to its size. We had to make sure that it would pass under all the overpasses on I-65 from Louisville to Indianapolis. [...]

Power Plant 7000 HP ID Fan Motors

          A Power Plant Customer’s Generating Station is located outside of Sullivan Indiana about 45 minutes South of Terre Haute. This coal fired plant went on line in 1982 operating two units producing 1080 megawatts. Horner’s shop in Terre Haute has been doing repair work for them since before the plant was operational. They continue to be a strong customer after almost 40 years. Each year they shut down one unit for maintenance so motors come into our shops for repair and Horner’s field service divisions are involved with removals and installations. Most motors are on a [...]
