Oil Filter Manufacturer Press Upgrade Project

Most of us are old enough to remember the oil filter commercial tag line, “pay us now or pay us later.” Well, those oil filters are made in a facility in Greenville OH and are stamped out on several large stamping presses. These presses were designed with eddy current clutch and motors to drive the press flywheels to enable variable speed operation. Over the last 30 years, the clutch drives have required high maintenance and were undependable. Now on to the solution; Mark Russell (outside sales) had several meetings with engineering staff with assistance from Dave Whited (product sales), Kim Shellabarger [...]

Motor Steel Bases at Pumping Station

We were called to a very rural pumping station in Kentucky. We had to remove two motors from there for repair. When those motors were removed, there were some real issues discovered with the steel bases they were mounted on. One was over filled with grout, and actually bedded the motor into the grout. The grout had actually flown up in between the fins on the bottom of the motor. The correction of this may be a future article, but without correction, this motor will never be able to be moved for alignment! The point of this article is to discuss [...]

Horner Rescues Motor Manufacturer Hit by Tornado

A motor manufacturer that produces motors for the rail industry. Their facility in Dayton OH was devastated by a tornado on Memorial Day weekend, last year. Since then, the Horner Industrial Springfield Division has been assisting their engineers to get their products tested and prepared for shipment to their customers. Last month, we were asked to start up a program to wind new 100 HP fan stators for the customer. They sent one of their winding engineers to our shop for a week to teach us their winding methods and materials. The engineer was a winding supervisor at the Springfield shop, [...]

Pipeline Motor Base and Loctite Coatings

A Pipeline Company had a project that was going late into October due to a 1250HP 4160V motor upgrade to a more modern frame. Once the original large existing GE 2300V motor was removed from the sled base, the surface was checked for flatness and it was found to be out close to .125”. This obviously was not acceptable for a 2 pole motor that was direct coupled to a Sulzer propane pump. Matt Phelps of Horner Fan&Fab had quoted a transition base for the newer 4160V more modern frame to meet the D dim. (shaft height). The general practice for [...]

Dredge Motors

A gravel pit in Petersburg, KY contacted John Baumann (Sales) with a problem. They had 2 motors on a dredge. A particular dredge is a floating clam shell type bucket that pulls gravel off the bottom of a lake. The motors drop and pull up the bucket from the bottom of the lake. The team at the gravel pit wanted to upgrade from a wound rotor motor and convert it to a new induction motor to be controlled by a VFD. They also wanted to upgrade the controls to eliminate a diesel generator and go to shore power. If they run [...]

2000 HP DC Shredder Motors

A recycling scrapyard in Dayton, OH had a few problems with one of two 2000 HP DC motors. The outboard motor was going through brushes and they were having flash-over issues causing field coil damage. The 2 motors are coupled together to run a shredder that shreds anything from cars, and scrap iron, to office furniture etc. The customer’s spare motor was sent to our shop at Washington Street to make sure the motor was ready to go when it was switched out with the motor needing repair. Washington Street bought and installed a new coupling and then sent the motor [...]

Power Plant Outage

A power plant in Indiana had Horner recondition 6 large motors during an outage they had in April. The Power Plant is a coal fired electric generation plant. The key component of the power generation plant is the boiler, and is also called the steam generator. The essence of the power generation plant is to create the steam in boilers. This steam is sent at high pressure to a turbine that generates electricity. The coal is first crushed into small particles using equipment called pulverizers. A joint effort between the Terre Haute Shop, the Washington St. shop, and field service helped [...]

Asphalt Plant Exhaust Fan and VFD Project

When you think of Asphalt you think of Roads. And if you’re in the Midwest you know how important it is to have these plants up and running with all the pot holes. The asphalt plant is mainly composed of cold aggregate supply system, drum dryer, coal burner, coal feeder, dust collector, hot aggregate elevator, vibrating screen, filler supply system, weighing and mixing system, asphalt storage, bitumen supply system. All these components have characteristics that impact not only the overall quality of the asphalt but also the effect on the environment. The plant had recently added a new line and had [...]
