Sine Wave Filters Sine Wave Filter FN5020 -Sine wave output filter for high-speed motor drives

Sine wave output filter for high-speed motor drives
• Smoothing of PWM drive output voltages
• Increased service life of expensive high-speed motors
• Reduction of audible motor noise
• Improvement of system reliability
• Production up-time for mission critical applications


Features and Benefits
1. Suitable for fast rotating fields up to 600 Hz
2. Conversion of the PWM output signal (symmetrical voltage components) of motor drives into a smooth sine wave with low residual ripple
3. Elimination of premature motor damage caused by high dv/dt, overvoltages, motor overheating and eddy current losses
4. Significantly increased service life of expensive (high-speed) motors
5. Reduction of the pulse load of motor drive IGBTs and the parasitic losses on long shielded motor cables
6. Less interference propagation towards neighboring equipment or lines
7. Advanced choke design to minimize filter losses and voltage drop
8. IP 20 protection, touch-safe terminals and temperature monitoring function to increase overall equipment safety
