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 [...]

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 [...]

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 [...]

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 [...]

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 [...]

Made In Japan, Rebuilt In The US

Everyone is well aware of the quality of Japanese autos in today’s market.

This off-shore challenge resulted in the upgrade of quality for all American automakers, just to remain in business. This quality concept also applies to the motor repair business and is why our company has Quality Manager like Vernon Pratt, to help us keep quality at the forefront of our [...]
