Helwig Carbon BPK — Say Goodbye to Arcing, Fluting, Burnt Grease, and Bearing Failure
Motors driven by Variable Frequency Drives (VFDs) are susceptible to damaging electrical discharges that seek the path of least resistance to ground, which is typically through the motor bearings. When these currents pass through the bearings, electrical arcing takes place leading to fluting, pitting, burnt grease, noise, vibration, and eventual bearing failure.

Helwig Carbon’s BPK Probe
Helwig’s BPK Probe measures the shaft voltage of VFD and DC-PWM controlled motors. An easy-to-use device used to determine if the bearings are at risk of damage from induced shaft currents. The device will display a pass / fail test result. A higher risk or volts present on the shaft will trigger a FAIL result,…
