Process Equipment Repair Opportunity

Most customer accounts begin with small motor repair jobs and then graduate to larger motors and driven equipment repair work such as fans, gearboxes and pumps. A few of our customers have specialized process equipment that also needs service work to keep production rolling. One of our customers produces only one product – cellulous fiber, and they cannot make enough of it to satisfy the consumer demand for this product. Cellulose is found in all plant matter. This customer uses large rolls of white paper as their only source of cellulose. The wood pulp in the paper along with the starch [...]

Corn Syrup Plant 300HP Drives Project

Where does High Fructose Corn Syrup come from? Horner has a customer that processes corn to make HFCS. This customer processes 230,000 bushels of corn every day that is used in almost every soft drink you purchase. If you look at a label and it has HFCS on that label, it could have been processed at this plant. HFCS does not have to be a liquid product. It is also processed as a dry product. The dry form of HFCS is super sweet, 2-3 times as sweet as liquid, and is processed by running it through a centrifuge made by a [...]

Compressor Room Electric Motor

A call came in late Friday from a customer planning to have their maintenance team do an onsite bearing change on a production compressor motor. We had the bearings in stock and set aside for them, however, Monday morning I received a call letting me know that they weren’t able to complete the work in house and requested Horner Field Service to come assist as soon as possible. We sent a team that morning to pull the motor and get it in to the shop for evaluation. Once onsite, they found that the compressor room is not accessible with a forklift. [...]

Sawmill DC Motor

Last summer, we received a call from the maintenance manager of a large sawmill. To get an idea of equipment size, this large bandsaw cuts 6’ diameter tree trunks into quarter pieces. A large carriage carries the log and feeds it into a large bandsaw with a blade that is 12” wide. The quarter pieces then go to smaller saws to cut slab boards. The complaint was that the large DC mill motor was making noise. Our field service supervisor, Jim Delawder, investigated and found that the banding on the commutator end of the armature had fractured and was flopping against [...]

13200 V 2000 HP Vertical Motor

Can you even imagine how many 60,000,000 gallons a day of water looks like? A good-sized bath would hold 40 gallons and a million gallons would be 25,000 baths. A water utility company recently sent in a 13,200V, 2,000 HP Vertical Motor to be rebuilt. Due to Capital Improvement programs the city and the Preventative Maintenance Team said this motor was due for a rebuild. This motor supplies energy for a 60,000,000 gallon a day vertical pump pumping potable water to the city. This facility has been going strong along the Ohio River since 1860. This was a total rewind on [...]

Cement Season at Horner

It’s cement outage season in Indiana with Horner doing work in Greencastle, Louisville, Logansport, Speed, and Mitchell IN. A Central Indiana cement plant is conducting their largest Maintenance and Repair outage in 20 years. They needed to replace an entire section of both the kiln and raw mill. The company brought in a 700-ton mobile crane to the plant site requiring 78 semi loads of support to set up. The time needed for these extended kiln and mill repairs allowed the customer to do all other outage work in the same 6-week timeframe. Washington Street, Terre Haute and HMS are all [...]

Ski Lift Motors and Controls

In September of last year, John Baumann (Sales) and Jim Delawder (Field Service Coordinator) inspected a ski lift at a ski resort located north of our Springfield OH shop. The resort had recently been purchased by a large conglomeration of ski resorts, located in Vail Colorado, and the new owners realized the need to update their ski lift motors and controls at this particular resort. After a complete inspection and some discussion, we quoted an upgrade package for one of their ski lifts, consisting of a new Toshiba motor, ABB drive, and other control components. John and Jim did a great [...]

Toshiba Drive Assembly

        We are in the process of working on a project at a major University. What’s interesting is what they’re going to be using the equipment for once we’re completed. The Toshiba Medium Voltage Drive assembly has been put in place. It is 27 feet long and 8 feet tall. The unit is fed with 13,999 V power that reduced to 4160V through a built-in transformer that powers power to the 4160V VFD section of the unit. Horner Field Service Techs Rick Collins and Gary Anderson were able to set and connect the equipment on site with the [...]

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 [...]
