Highsine™ (240 - 500 Hz)
CTM Magnetics HighSine sine wave filters are designed for optimal performance at high frequencies 240 Hz – 500 Hz motors. The HighSine product line is engineered to meet rising demand for high frequency/ high speed motor drive systems. Applications such as high speed chillers, high speed electric submersible pumps, compressors, and blowers all require high frequency sine wave filtering. CTM Magnetics HighSine sine wave filters are designed to meet this rising need.

The Optimal Solution for High Frequency Motor Protection
High 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. With the rise of high frequency/ high speed permanent magnet motors the need for higher frequency sine wave filtering has increased. CTM Magnetics HighSine sine wave filters are designed to meet this rising need without requiring costly derates that negatively effect system size, efficiency, and cost.
Maximum Motor Lead Length:
Damaging voltage waves occur when motor lead lengths reach a characteristic length. These reflected voltage waves can cause damage to cable insulation and motors. By filtering the drive produced PWM waveform to a near perfect sine wave, CTM sine wave filters minimize harmful voltage, allowing for longer motor lead lengths (up to 15,000 feet in certain applications).
Stop Rewinding Motors:
Installing a CTM sine wave filter eliminates harmful voltage spikes, reducing insulation stress. 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 the life and reliability of the entire system.
