High Frequency Motor Applications Require Extra Filtering High frequency PM motor applications lead to higher harmonic distortion for the entire motor drive system. To account for this one can either reduce the harmonics by derating the VFD, increasing the drive cost...
GridHawk Passive Harmonic Filters CTM’s GridHawk series passive harmonic filters boast several key advantages over market standard harmonic filters. These advantages include: 5 year capacitor warranty. high reliability poly-film capacitors High grid voltage distortion...
Film Capacitor Advantages CTM Magnetics utilizes high-reliability poly-film capacitors. Compared to the electrolytic capacitors used in competitors’ filters, CTM's film capacitor advantages include higher temperature ratings, higher surge voltage ratings, lower ESR...
Sealed Contactors Protect Outdoor Harmonic Filters Many harmonic filters use NEMA 3R outdoor cabinets in blowing dust or high humidity environments. A harmonic filter waiting in the field for 30 days to be connected can collect enough dust on the contactor to fail on...
Common Mode Noise Protection Common-mode (bearing) current can have disastrous effects on induction motors, leading to electric fluting and premature bearing failure. Conventional sine wave filters introduce substantial common mode noise that will damage the motor....
The Problem With Cable Length Long cables increase harmonic distortion for the overall motor drive system (figure 1). CTM discovered the effect of cable lengths on harmonic distortion through customer provided field data. Due to the additional noise generated from the...
