Winding Redesign

An employee owned manufacturer in NW Ohio had a critical GE 400/200 HP large frame two speed Mill motor failure. After we received and inspected the motor, the form coil winding had failed. This was the first winding failure on this motor in 30 yrs. Unfortunately they had no spare. The search began for an E-OK motor to rebuild in order to reduce the downtime based on the time required for a form coil re-wind. Six motors were potential replacements but all would require major field motor base and fitment requirements. During a discussion with the customer they stated the 400 [...]

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 [...]

1937 DC Stainless Steel Manufacturer Motor

A good customer who manufacturers stainless steel had a power outage recently. When power was restored, the motor failed due to condensation from the unheated building. This motor was built by the Army Corp of Engineers in 1937 and came out of a boat from WWII. Field Service came onsite to inspect the motor and found that the fields were grounded and the armature was not far behind. Luckily, this customer had a spare in their warehouse. They decided it was the quickest to take that spare motor out and send it to Horner to repair and get it running. Due [...]

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 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 [...]
