Cement Plant Raw Mill Motors

A Cement Plant in Louisville decided to purchase a spare 4500 Hp motor for their Raw Mill to back up a motor that had been in operation for years. A Raw Mill is a piece of equipment used to grind up materials into a raw mix during the manufacture of cement. The raw mix is then fed to a kiln, which transforms it into clinker, which is then ground to make cement in the cement mill. The company did their due diligence and sought out quotes for a replacement motor. When all of the quotes came back, they were surprised at [...]

Environmental Gas Company Repair

An Environmental facility on the southside of Indianapolis draws gases off the large Landfill next door. They then filter, clean and dry the gas and then sells they turn around and sell the flammable gas to Utility companies. Our first call came in to help them with a pilot bearing replacement in the bottom of a tank that holds a mixer blade in place that mixes a solution that scrubs the methane gas to make it cleaner before it is sent to their customer as fuel. Horner’s Field Service Technicians on site discovered a lot of problems going on. The pilot [...]

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 [...]

Roof Mounted Exhaust Fans

A Warehouse and Logistics Company was having electrical problems with three roof mounted exhaust fans. Apparently when installed they had been wired incorrectly. Time took its toll and the units eventually stopped working. The electricians who were called in to evaluate the unit, contacted Horner to evaluate the unit from a mechanical perspective. As suspected, the fans had been installed incorrectly as well. Upon inspection by Horner the following issues were found: incorrectly wired motors – causing failure and incorrectly mounted frames – causing belt wear, sheave deterioration and bearing failure. The customer had the units removed from the roof and [...]

Field Service/Pump Repair Go Diving

We were asked to remove a 600 HP vertical motor and the 13 foot long turbine pump that it couples to, from a cooling tower water basin. The motor was removed without incident, but when we lifted the pump out, instead of the expected 13 feet, we only got 5 feet of pump! The pump had actually broken in two! We probed the water, using 8 foot long poles, and could not feel anything. And with caramel colored water in the cooling tower, nothing was visible. The customer had no way to get it out, and even if a new pump [...]

Pallet/Mulch Manufacturer Rescue

A Saturday at midnight Horner rep Dennis Cardwell received a call from a local pallet/mulch maker saying that their 750 HP motor had broken the shaft. Dennis set into motion after hours to see if a motor could be located only to find the motor was a special OEM build and we could not quote the motor. Not being satisfied with this Dennis contacted Craig Hallett (Inside Sales Manager) for a meeting to see if we could find a motor that would come close and perhaps do some modifications. As it turns out we located a stock 800HP TECO-Westinghouse motor with [...]

60 HP Integral Vertical Pump Motor (Water Cooled) Assembly

A Louisville customer recently brought in a 60 hp integral vertical motor pump assembly where the motor was water-cooled. The circulation tubes running through the stator had clogged with lime buildup causing the motor to overheat which resulted in the motor windings being burned to a crisp. The customer came in to witness the teardown and to discuss options to prevent future unplanned downtime, as this had happened numerous times before. As it turns out the customer has four of these same pumps in remote locations without monitoring devices so there’s no way for them to tell when the water stops [...]

Marine Field Service Work: Riverboat

The first week of July is always the busiest week for our field service group. As luck would have it, I received a call from two customers for field service work – on the water. Service Call #1: I consulted with Rich Streitmarter, Ralph Coonce and Jim Delawder and of course, our field service resources were tapped out. Jim offered to pull a new field tech, Gabe Mercuri, from a job if I could assist him as Gabe has only been with us for about a month. The good news was that Gabe has a lot of mechanical and hydraulic experience [...]

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 [...]

Pipeline Motor Base and Loctite Coatings

A Pipeline Company had a project that was going late into October due to a 1250HP 4160V motor upgrade to a more modern frame. Once the original large existing GE 2300V motor was removed from the sled base, the surface was checked for flatness and it was found to be out close to .125”. This obviously was not acceptable for a 2 pole motor that was direct coupled to a Sulzer propane pump. Matt Phelps of Horner Fan&Fab had quoted a transition base for the newer 4160V more modern frame to meet the D dim. (shaft height). The general practice for [...]
