DV/DT Filter Prevents Premature Motor Damage


FN510 dv/dt filter which eliminates premature motor damage caused by high dv/dt, over-voltages on motor cables, motor overheating and more, to prolong service life motors in high precision environments.


Suitable for motors from 1.5 to 30 kw with frequencies up to 400 Hz (4 to 24 amp) or to 200 Hz (33 to 66 amp), this proven technology reduces high output voltage dv/dt from IGBT motor drives and restricts over-voltages caused by line reflections on motor cables.



  • servo drives
  • closed-loop vector drives
  • machinery with servo or torque motors
  • robotics
  • pick-and-place machinery
  • motors with short to medium cables
  • where sine wave filters are not applicable
