Output filters for ac motors
Schaffner’s FN5060 dv/dt filters are designed to protect AC motors from destructive effects of peak voltages and inrush amps, increasing service life and system reliability. This patented technology protects motors and adjacent equipment without capacitors or resistors. They reduce high output dv/dt from IGBT motor drives and eliminate over-voltages caused by line reflections on motor cables. These filters fit for loads up to 760 vac, 30 to 1200A and motors up to 60 Hz. FN5060 dv/dt are suited for motor drives, servo or torque motors, HVAC equipment, elevators, hoists, and process equipment. Compact, resistor-less design saves floor mounting space and installs easily. These filters are also suitable for applications with frequent braking, danger of flash-over voltage, and motors running at high temperatures.
