German Engineering Gearbox

Anyone who has worked in the field of electromechanical repair has likely come across one or more pieces of German engineered equipment. It doesn’t take long to figure out the Germans have a unique way of engineering their products and for the most part, are not repair friendly. Recently our shop repaired a Knodler CMG gearbox that was designed and built in Germany. The design of the CMG gearbox is to solve a problem of needing a large amount of torque in a small package, and this gear- box does that well. CMG is an acronym for “compact motor gear” and [...]

3000 HP Cement Motor

After having successfully cutting coils from a stator on site four times previously, the 3,000 HP stator finally died and had to be scheduled to be rewound at a cement plant in KY. The removal of the motor is not the conventional way you think of a motor being removed, you start by removing the outside wall of the building it is in, and then sticking the boom of the crane inside the building to be able to lift the motor. standing at a safe distance from the equipment, the motor does not look all that large, but as if gets [...]

Aluminum Plant Outage

A major aluminum manufacturer contracts Horner EMDS (Electro Mechanical Diagnostic Services) to perform monthly vibration data collection and analysis. EMDS identified a mill gearbox input shaft bearing issue. In 2022, the monthly vibration analysis indicated the bearing issue increasing. The vibration analysis was discussed with the customer and the vibration data collection increased to twice weekly. At the same time, customer was planning a major outage to on-site repair the gearbox. The March outage was scheduled. Horner provided 24 hour per day, 5-day work schedule. On a Monday the outage started. Mark Rosebrock was lead tech on day shift and Matt [...]

Power Generation Plant Water Pump Motors

A coal fired power generation plant had a planned outage to maintain equipment and Horner was onsite to remove 2 1250HP vertical pump motors. These motors pull water from the reservoir for cooling purposes and heat exchangers. These motors were taken out for routine maintenance, basic reconditioning and to replace bearings. Onsite to help with the removal was Indianapolis Field Service Don Pence, Louisville Field Service Joe Dupont and Terre Haute’s Eddie Piper and Jeremy Brown. Crane service had to be scheduled and coordinated to pull the motors out. The bearings for these motors are specialized thrust bearings and were replaced [...]

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 [...]

Powerplant Turbine Vent Fan/Motor

A power plant’s combined cycle generating station contacted Horner Salesperson Joseph Motz on Friday 12/16/22 regarding one of the Turbine Vent fan motors which had failed and was going to need to be replaced or repaired. As this motor is not accessible while the Turbine generator is running, Horner could not verify Motor dimensions for the possible replacement of the original OEM motor. The Station had a spare fan, but it did not come with a motor. Upon inspection of the fan and Impeller in the customers storeroom, it was noted that the base could accommodate the metric frame motor but [...]

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. [...]

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 [...]

Finish Ball Mill Motor

A 1350 HP Synchronous Motor out of a cement plant in Ohio was called out to bid and Horner won that bid. This finish mill motor comes out of a cement plant in the ball mill. The ball mill is a big round pipe that is full of steel balls the size of a softball. As the pipe turns it has blades welded on the inside which carry the balls up to the top of a 16-foot diameter pipe and the balls fall to the bottom of the pipe where the rocks are. The weight of the balls smash the rock [...]

Horner Named GE Wolong Approved Repair Center

GE Industrial Motors, (GE-Wolong), has granted Horner Industrial the rights to conduct Warranty repair on their Motor Product line. Horner Industrial and GE have had a long-standing relationship over the years. When the GE Motor line was sold to Wolong over two years ago our long-standing relationship with GE was severed and our Warranty status was put into limbo. Horner Industrial is proud to announce that effective October 1, 2021, GE Industrial Motors has once again reinstated Horner Industrial as an approved Warranty Repair Center for their product line. This will allow Horner Industrial the opportunity to work directly with GE [...]
