Sine 60TM (60 Hz) Sine Wave Filters

The Optimal Solution for 60Hz Motor Protection

Product Overview

CTM Magnetics Sine 60™ sine wave filters are designed for optimal performance with line frequency, 60 Hz, motors. Attenuated for PWM switching frequencies as low as 2 kHz (and up to 20 kHz), Sine 60™ (60 Hz) sine wave filters will meet your most demanding motor filtering needs for all 60 Hz applications. CTM Sine 60™ sine wave filters are available in multiple packaging configurations and come with both air and liquid cooled options.

Patented Technology:

CTM sine wave filters utilize patented technology that provides superior filtering performance across a wide variety of fundamental frequencies (60 – 500 Hz). Additionally, with patented liquid cooled technology, CTM sine wave filters offer the highest power density solutions available to the market. Moreover, with a CTM liquid cooled product, 97% of the product’s heat is captured by the coolant and removed from the cabinet. Furthermore, removing this heat protects any heat sensitive electronics in the cabinet. Due to superior materials and geometric shapes, magnetostriction-induced noise is significantly lower in CTM filters. Therefore, CTM products are quieter, “stealthier”, solutions for applications where noise is an important factor.

Custom Solutions:

For unique applications, CTM provides semi and fully custom solutions. The CTM engineering team will work with you to design a product that meets even the most challenging application requirements. Because of our unique design software, CTM is able to produce custom designs in as little as two business days. If you have any questions or need help finding a product give us a call today or submit a form through our contact us page.

CTM is the leading choice in power quality products because of our unparalleled capabilities. CTM offers the highest filtering, smallest package size, lowest noise, highest power density, no common mode noise, and competitive prices. Contact CTM today.

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. Low Audible Noise Due to superior materials and geometric shapes, magnetostriction-induced noise is significantly lower in CTM filters.

Sine Wave Filter Applications

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 and 2.5+ kHz switching frequency. Contact CTM for operating unit above 120 Hz. 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 350 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.

Motor Protection 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. Maximum Motor Lead Length Reflected voltage waves occur when motor lead lengths reach or exceed a characteristic length of the system, which is dependent on the voltage rise times (dV/dt) in the cabling. By filtering the PWM waveform to a near perfect sinusoidal waveform, CTM sine wave filters minimize dV/dt, allowing for longer motor lead lengths (up to 15,000 feet in certain applications). Stop Rewinding Motors Installation of a CTM sine wave filter eliminates harmful voltage spikes, which reduces insulation stress. Additionally, CTM sine wave filters lessen harmonic current distortion, thereby minimizing unnecessary motor heating. By reducing winding stress and motor heat (two primary causes of motor winding failure), motor winding breakdown and failure is greatly reduced, minimizing the need to constantly rewind motors. Extended System Life and Reliability CTM sine wave filters greatly reduce voltage stress and excess heat not just for the motor, but for all other load side components, greatly extending life and reliability of the entire system.
