EC: AEGIS Shaft Voltage Tester Digital Oscilloscope

Hardware — Handheld test, measurement, calibration: The AEGIS Shaft Voltage Tester Oscilloscope makes it easy to take/capture readings of harmful VFD-induced shaft voltages from spinning motors and to prevent costly bearing damage/downtime by installing AEGIS Rings. This is a Control Engineering 2017 Engineers’ Choice Awards Finalist.

Motors controlled by variable frequency drives (VFDs) are at risk of electrical bearing damage. The new AEGIS Shaft Voltage Tester Digital Oscilloscope makes it easier than ever to check motors for damaging VFD-induced shaft voltages and prevent costly bearing damage and unplanned downtime.

The AEGIS Oscilloscope is specially configured to take and capture accurate voltage measurements from spinning motors shafts. The CAT II/III oscilloscope comes with a special conductive microfiber tipped probe for exceptional shaft contact, probe holder with magnetic base, and compact carrying case. The 2-channel, 100 MHz oscilloscope has a 5.7-in. TFT LCD color display, a multi-language user interface, and a 5-hour rechargeable/replaceable lithium-ion battery pack. It is capable of sampling rates of 1 GSa/s to 50 GSa/s and has a USB port for data transfer or flash drive storage. By pushing and holding the "Save" button for 6 seconds, the scope’s handy AEGIS One-Touch screen capture capability saves screen images to a USB, dramatically simplifying data collection for analysis/reporting. The AEGIS SVT Oscilloscope can be configured for a variety of languages, including English, German, French, Italian, Spanish, Portuguese, Russian, Simplified Chinese, Traditional Chinese, Korean, and Arabic.

The AEGIS Shaft Voltage Tester combines oscilloscope, multimeter, and recorder functions in a single unit and provides measurements for resistance (ohms), continuity, diode capacitance, dc volts, ac volts, direct current, and alternating current—all at 6000 count display resolution.

AEGIS Shaft Voltage Tester Digital Oscilloscopes are offered in several packages. Accessories include 9V/4A power adapter, 1X/10X oscilloscope probes, test leads for the multimeter, probe calibration tool, rechargeable/replaceable 5-hour battery, and USB flash drive with user manual.

If harmful shaft voltage levels are found, installing an AEGIS Ring will divert these voltages safely to ground, extending motor life and ensuring the reliable, long-term operation of the VFD-driven motor system.
