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.

Linear Motor

Nippon Pulse America (Radford, VA) released the SL083 scaleless linear motor with a built-in linear encoder for positioning applications that would benefit from the repeatability, reliability, and robustness of a linear motor, with up to 5 μm in resolution. The motor consists of a tubular stainless steel shaft and a non-contact forcer. It requires no lubrication, and features a non-critical air gap that eliminates variation in the force. The housing is made of non-magnetic aluminum.

Panel-Mount Piezo Drives

The Ndrive QLe digital, panel-mount nanopositioning piezo drives from Aerotech (Pittsburgh, PA) are designed for use with the Aerotech Automation 3200 (A3200) motion controller. The drives enable coordinated motion between piezo stages and servo axes at higher rates than other controller/drive products. Featuring a dual-core, 456-MHz, floating-point DSP, the drives feature position latching and single-axis or multi-axis position synchronized output (PSO) to generate pulses based on actual position feedback.

Encoders

Celera Motion (Bedford, MA) introduced the MicroE Veratus™ Series encoders incorporating VeraPath™ technology. All interpolation, automatic gain control (AGC), and signal processing is performed in the sensor head that measures 35 × 13.5 × 10 mm. Interpolation in the sensor head provides resolution from 5 μm to 20 nm for linear applications, with speeds up to 5 m/s. The encoders feature multiple mounting configurations, industry-standard analog and digital incremental encoder outputs, built-in limits, flexible index selection, and status LED in the sensor head.
