Servo Motor / VFD Filter SF20101

OnFILTER' Servo Motor / VFD Filter SF20101

Servo / VFD EMI filters help to substantially reduce EMI in the equipment and to protect motor's bearing from EDM-caused fluting.  These patented filters are complete multiple-mode filters, providing comprehensive noise reduction, not just reactors.

This model of servo motor/VFD filter is most suited for motors consuming up to 10A.  For higher currents please see our 20A versions.  For lower current applications see our 3A model.   If you are looking to include an AC input filter for the drive, please see our combo model which combines in one small package both motor and AC filters.

Thanks! We will get back to you soon.

"We tested the servo filter on another system, this time with Kollmorgen motors. We saw another significant reduction in noise on our signal"  (P.M.,U.K.)

If you are not sure which specific model would work with your drive/motor, send us a legible photo of drive and/or motor label and if you know, the specific models 

  • No mechanical attachments

  • No changes in software
