FN 5060

Output Filter for Motor Drives


<ul><li>Efficient reduction of high output voltage dv/dt from IGBT motor drives (as per IEC 60034-17/25)</li><li>Restriction of overvoltages caused by line reflections on motor cables (as per IEC 60034-17/25)</li><li>Protection of motor winding insulation from premature aging and destruction</li><li>Increase service life of electric motors</li><li>High reliability and production up time for mission critical applications</li><li>Less interference propagation towards neighbouring equipment or lines</li><li>Output filter with low impedance, ideal for processes requiring exceptional precision and reproducibility of movements</li></ul>

Features and Benefits

Reduction of drive output voltage dv/dt
Reduction of voltage stress at motor windings
Protect AC motors from destructive effect of peak voltages
Increase of motor service life
Improvement of system reliability


Typical applications

Motor drive applications with short to medium motor cable length
Machinery comprising servo or torque motors
HVAC equipment, incl. pumps, fans and compressors
Conveyors, elevators, hoisting and cranes
Applications where sine wave filters are not suited (e.g. high dynamic operation)
