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. [...]

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 [...]

Advanced Diagnostic Services and Preventative Maintenance

A major steel mill was looking to upgrade their maintenance practices thru predictive maintenance vibration analysis. There were several meetings with Brad Barton of Horner’s Electrical Mechanical Diagnostics Service (EMDS) group to identify equipment and understand their expectations. The EMDS reporting was covered in depth, a vibration collection route was laid out and frequency of reporting established. The machines identified ranged from 10,000 hp AC motors to smaller AC and DC motors in the range of 100hp up to 1250 hp as well as gearboxes. Horner’s field service group installed remote accelerometers on equipment deemed not safe for personnel to enter [...]

Centrifugal Force – What Is It?

The words “centrifugal force” were first used in the year 1698, so it is far from a new concept. A dictionary definition is “the apparent force that is felt by an object that is moving in a curved path that acts outwardly away from the center of rotation.” We have all felt the effects of centrifugal force when we are driving our car or truck and turn a corner at a high rate of speed. As long as we are moving in a straight line, we do not feel this force but when we exit the highway at a high rate [...]
