Reliable VFD Cables Boost Productivity, Minimize Downtime

From fans and blowers to 24/7 production line equipment, variable frequency drives (VFDs) are a mainstay of the industrial world due to their remarkable ability to improve the efficiency of motor-driven equipment. As part of a complete VFD package, high quality cable is one of the most important components in terms of achieving maximum productivity and minimizing downtime. When designing a robust VFD cable, the materials used in its production are critical to ensuring that the cable’s electrical properties will guarantee peak performance. For system engineers and others involved in specifying VFDs, cable quality should be one of the most decisive factors.

Driving Auto Performance Through Lubricant Selection

Underhood temperatures are gradually rising as aerodynamics dictate tighter packaging and large engines are being replaced by smaller turbocharged and supercharged engines for improved fuel efficiency. With ambient temperatures under the hood exceeding 120 °C (248 °F), finding a lubricant that can withstand the high temperatures for an extended period of time is key.

DryLin® E7 plastic linear plain bearings versus PTFE-lined plain bearings

Linear plain bearings are becoming commonplace in today’s manufacturing industry. As technologies and material sciences have advanced, so have the capabilities of linear plain bearings, particularly those made of plastic, such as the DryLin® series of self-lubricating linear bearings from igus®. This whitepaper will compare how they outperform a competitive linear plain bearing technology, which uses a PTFE-based, bonded liner, in both wear and friction testing.

Sense Element Pump Ripple Fatigue

Aerospace sensor technology is plagued by the balance between sensitivity and durability. As devices become more fragile in the pursuit of achieving higher accuracy they find themselves torn apart in the process. Hydra-Electric solves this using a special sense element of stainless steel construction capable of withstanding the harshest pressure spike environments without the use of a snubber. Using finite element analysis, it was revealed that near infinite fatigue life is achieved even in high pressure applications. This demonstrates the superiority of a stainless steel flexure sense element over conventional piezoresistive silicon (PRT).
