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:
One-time installation can be performed on site in a matter of minutes
Only one choke is needed per system, not per motor
No shaft contaminant issues with installation occurring on non-load side of the motor
Current absorption occurs before it reaches motor
No extra equipment is needed to accommodate keyway access or wash-down environments
CoolBLUE has a simple range of product sizes which can fit all types of motors, making selection easier
