CoolBLUE Inductive Absorbers

CoolBLUE inductive absorbers are a newer approach to managing noise on the power cables connecting variable frequency drives and electric motors. Rather than traditional insulated bearings and shaft grounding rings, CoolBLUE absorbers act as a common mode choke and dissipate noise on the power cables into thermal.

This method significantly increases the service life of motor bearings while reducing maintenance time and costs. Other benefits include:
