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 20A. For lower current applications see our 3A and 10A models. 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 EMI filters.
