Lower the capital investment (CAPEX) of your motor drive system. Avoid costly derates, without sacrificing performance. A better solution exists today.   CTM HighSine™ & FlexSine® Filters  Lower the capital investment (CAPEX) of your motor drive...

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...

Decreases in permanent magnet synchronous motor (PMSM) costs are leading to increased utilization in high power applications due to benefits in energy efficiency, partial load efficiency, and decreased motor size. Typically, low pass sine wave filters are used to...

Microgrids are Growing Washington state received $7 million from the state's Clean Energy Fund, which has been earmarked to improve the efficiency, security, and reliability of Washington's electrical grid. A portion of the grant is being applied to build a microgrid...

Thanks to Michael Faraday's work in the early 19th century, electricity has been generated at centralized facilities beginning in 1882, initially using coal and water power. In the past 135 years, other non-renewable fuels—oil, natural gas and nuclear—have joined coal...

CTM MAGNETICS RECEIVES ISO 9001:2015 CERTIFICATION CTM Magnetics has been certified under ISO 9001:2015. This certification verifies that CTM is aware of and complies with the requirements recognized to produce quality products. CTM Magnetics is a design, engineering...

Due to higher densities, specific heat capacities, and thermal conductivities, liquids are generally much better cooling agents than gases. Compared to air, water has a heat carrying capacity 3,500 times higher than that of air, and a thermal conductivity 24 times...
