Steel Rolling Tandem Mill Motor

A steel manufacturer sent in a steel rolling tandem mill motor after the armature equalizer insulation had failed to ground due to age and time of service. The bearings, bearing journals, and bearing housings were severely damaged. A team of different Horner Divisions came together to complete this project. Machining Services did an extensive amount of machine work on the shaft and bearing housing. They also turned and undercut the armature when the rewind was completed. Fan and Fabrication manufactured new bearing seal inserts. Horner Coatings sprayed and machined the shaft and bearing housings. They also did the welding of the [...]

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. [...]

Complex Motor Rewind – DC Mill Motor

Horner Louisville had the opportunity over the Holidays to service a customer who is a plastics extrusion company. The motor came in on an overtime basis, so it was given top priority. The customer sent in a 75Hp FUJI DC Motor that, after disassembly, inspection and testing required a full rewind and machine work that included coatings work on the armature. However, this wasn’t your every day run of the mill DC motor. The motor was a random wound compound design which is known to be a little tricky to wind. Louisville’s winder, Charlie Mings, looked at the winding and was [...]

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 [...]

University Flood and VFD Protection

Recently, a larger University in Indiana suffered a flood in the Main Campus Library. During a large rain event, they had (2) 75hp motors with grounding rings exposed to water in the small basement mechanical room. Upon checking stock, delivery of new motors equipped with an internal grounding brush would be 5 to 6 weeks. As the motors are being operated by VFD’s, the customer wanted some form of protection against common mode current which could lead to bearing fluting and motor failure. Horner Salesperson Joseph Motz took the opportunity to present the Cool Blue and NaLA inductive absorbers to the [...]

DC Steel Mill Motors

The Horner Springfield division received a call from a steel mill customer, located in Columbus OH. They had a failure on a tandem pair of 850 HP DC motors on their rolling mill operation. Horner Industrial Springfield division had previously rebuilt their spare DC tandem mill motor set, including rewinding one of the armatures. Springfield field service techs removed the failed motors and installed the stored rebuilt motors, at the customer’s site. We also contracted with our local rigger to remove the 16,000 lb. motors and deliver them to our shop. There are still a lot of DC motors in operation [...]

Dough Mixers

We don't just fix large equipment. An opportunity recently came to Horner Louisville from a company who leases out Pizza dough mixing machines to Pizza stores along with other Restaurant equipment. As you can well imagine, these machines are treated like Rental Cars as nobody considers them their property and they’re not maintained very well. Horner Louisville secured the business after a competitor in Louisville took advantage of the situation and had increased their price to stratospheric levels. The units originally came in to Horner Louisville to have us check out and repair the motors which resulted in either a recondition [...]

Wind Tunnel TGF 5000 HP Motor

A customer contacted us to work on a TGF 5000 hp motor.  Trisonic Gasdynamics Facility.  What in the heck is a TGF.  A wind tunnel.  The AFB tests airplane models in a wind tunnel.  The wind tunnel air speed maximum is mach 3.5.  The 10 stage Allis Chalmers compressor requires 8500 hp.  A 3500 hp wound rotor motor couples to a Falk gearbox with the 5000 hp synchronous motor. This job started with the Springfield field service department. Jim Delawder inspected and tested the motor, determining that rewinding was needed. John Franzer and Mike Harper presented a quotation for repair to [...]

Non Standard 2000 HP Mill Stand Motor

What makes the Horner Motor Division stick out from most motor shops besides the breadth of services it offers is its ability to fix and problem solve non-standard motors and equipment. We employ some of the best winders and mechanics whose knowledge is incomparable. We received a 2000 HP Mill Stand motor from an aluminum plant for repair. Fractures were found in the risers exiting the commutator bars with a design from Siemens that would definitely be considered “non-standard.” Many of the design characterizations were due to lots of horsepower in a fairly small frame. We replaced the commutator, windings, and [...]
