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 [...]

Installing VFD Drives On Vertical Pumps and Structural Vibration Problems

By: Nelson Baxter It is well known that the installation of VFD drives has the possibility of introducing vibration problems on rotating equipment.  When a machine runs through a wide speed range the probability of operating at or near a resonance is significantly increased as compared to a machine operating at a single frequency. VFDs are generally utilized to slow the speed of a machine down to match the load, thus saving energy and allowing better control of the process.  The inherent nature of the design of vertical pumps means that there is a large mass (the motor) sitting on top [...]

CoolBLUE® Inductive Absorbers Redesign

Product CoolBLUE Inductive Absorbers COOLBLUE® NANOTECH® KITS Cool BLUE inductive absorbers operate in a similar fashion as a common mode choke by absorbing the damaging high frequency noise associated with VFD’s. Maximize equipment reliability, reduce maintenance costs associated with grounding rings, and avoid unscheduled downtime. The installation around motor cables takes less than 10 minutes. Simply disconnect the cables, install the cores around the cables, and reattach. Done! Applications Include Electric vehicles (EV) Agriculture Hospital/commercial/office buildings chillers Wind, solar, and other renewable energies Paper/bottling/food/chemical manufacturing Automotive manufacturing [...]
