Product Overview

Highest Filtering. Best Performance. At -22 dB, CTM Magnetics HighSine high frequency sine wave filters have the highest filtering capabilities of any market standard sine wave filter. The higher filtering leads to better performance which in turn leads to a lower motor drive investment. 

Stop Trying to Make Silicon Steel “Work”... Motor advances are driving the market to switch to faster spinning PM motors. These higher speeds lead to high frequency harmonic distortion at the output of the drive. Our competitors’ filters overheat under this additional stress, forcing them to derate their filters. Furthermore, competitors often demand higher drive switching frequencies (to decrease THID), which then requires a drive derating.

Patented Technology:

However, there is another option. Due to a unique patented design and proprietary materials, CTM’s HighSine sine wave filters are specifically designed for optimal performance with high frequency induction and permanent magnet motors. HighSine filters provide industry leading filtering while allowing for minimal VFD derating. The HighSine series offers standard filters optimized for use at 240 Hz, 333 Hz, 350 Hz, and 500 Hz @ 4 kHz, 5kHz, 5 kHz, and 5 kHz respectively.

Optimized for High Frequency PM Motors Designed specifically with high frequency PM motors in mind, CTM’s HighSine filters incorporate features to address concerns unique to these applications. For example, high frequency inverters often output higher harmonics than at line frequency. To address this issue, these filters are attenuated to remove a larger percentage of drive harmonics (see next page for additional details). No Filter Derating Competitors’ solution to high frequency motors is to force you to buy a larger filter and derate. The HighSine series is different. Due to a unique patented design and proprietary materials, the HighSine filter is rated at full current up to 500 Hz. Superior Materials Thermally designed to withstand frequencies that would burn other inductors, HighSine filters utilize advanced, proprietary materials to minimize heating and high current saturation. Multiple Designs for Enhanced Performance Multiple filter designs are offered at each current level, so that filter performance, capacitor current percentage, and cost are optimized for your application’s needs.

CTM Magnetics offers a broad portfolio of sine wave filters to meet all your motor filtering needs.

Sine 60 – The optimal choice for 60 Hz motor protection. Designed for up to 70 Hz fundamental and 2+ kHz switching frequency. FlexSine 120 – For both induction and PM motor applications. Designed for up to 120 Hz fundamental (Contact CTM for operating unit above 120 Hz) and 2.5+ kHz switching frequency. HighSine 240 – Perfect for high-speed, PM motor applications (240 Hz). Designed for up to 240 Hz fundamental and 4+ kHz switching frequency. HighSine 333 – Perfect for high-speed, PM motor applications (333 Hz). Designed for up to 333 Hz fundamental and 5+ kHz switching frequency. HighSine 350 – Perfect for high-speed, PM motor applications (350 Hz). Designed for up to 350 Hz fundamental and 5+ kHz switching frequency. HighSine 500 – Perfect for high-speed, PM motor applications (500 Hz). Designed for up to 500 Hz fundamental and 5+ kHz switching frequency.

Stop Rewinding Motors Harmful square waves, voltage spikes, and harmonic distortion are all filtered from the inverter output, reducing motor heating, wear, and winding stress, providing critical motor protection. Additionally, dV/dt reduction allows longer motor lead lengths (up to 15,000 feet). How much does it cost to rewind? No Common Mode Noise Common-mode (bearing) current can have disastrous effects on induction motors, leading to electric fluting and premature bearing failure. CTM offers the only sine wave filters that do not introduce common-mode currents. High-Reliability Capacitors CTM sine wave filters utilize high-reliability capacitors. Compared to the electrolytic capacitors used in competitors’ filters, CTM capacitors have higher capacitance stability with temperature, higher surge voltage ratings, and are low ESR for higher ripple current handling. Additionally, CTM capacitors are self-healing. All of these factors lead to boosts in system reliability and longevity. 100% Load at Cold-Start (Automatic Restart) Electrolytic caps have high ESR at lower temperature. Hence, in cold environments, they require time to heat up during start/restart. If this procedure is not followed, electrolytic caps will fail. On the other hand, CTM’s capacitors are ready for 100% load at all temperatures, leading to quick cold-starts and restarts.
