Toshiba Drive Assembly

        We are in the process of working on a project at a major University. What’s interesting is what they’re going to be using the equipment for once we’re completed. The Toshiba Medium Voltage Drive assembly has been put in place. It is 27 feet long and 8 feet tall. The unit is fed with 13,999 V power that reduced to 4160V through a built-in transformer that powers power to the 4160V VFD section of the unit. Horner Field Service Techs Rick Collins and Gary Anderson were able to set and connect the equipment on site with the [...]

Slurry Pump Project

We have a local gravel pit and asphalt operation near our Springfield OH repair shop. Over the years, we have built a solid relationship with this customer, doing field service, motor and mechanical repairs.

Initially, we looked at PF correction capacitors and then into AC drives as a way to improve power efficiency. The slurry system consists of three pumps – a fresh water pump, a sand pump, and a waste pump. All part [...]

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.

1500 HP DC Drive Changeout

One of our Horner customers had a mid 70’s Reliance Engineered Drive with an AB PLC-5, it was operating a Banbury Mixer application. The existing drive was damaged in a minor fire and was only operating on 3 out of 6 caps. Due to the damage and loss of pertinent feedback to monitor quality, our customer made the decision to replace the existing drive with a new Bardac DC drive. Bardac was chosen due to the availability of the drive which was 2 weeks out on an expedited basis. No other drive company could provide delivery inside 16-18 weeks. David Whited, [...]
