Measuring the shaft voltage on VFD-driven motors provides you with valuable information to determine if there is a potential risk of bearing damage from electrical discharges. We recommend surveying and documenting shaft voltage readings using the AEGIS® Shaft Voltage Tester Digital Oscilloscope. Download our Shaft Voltage Testing Guide here.
Examples of shaft voltage readings:
High Peak-to-Peak Common Mode Voltage
High Amplitude EDM Discharge Pattern
Low Amplitude Voltage Discharge Pattern
