FN5420

LC Sine Wave Filter for Motor Drives

  • Prevention of overvoltage on the motor
  • Reduction of motor noise
  • Reduction of motor losses
  • Increase motor service life
  • Possible to apply long motor cables

Features and Benefits

Converts the rectangular PWM output voltage of motor drives into a smooth sine wave with low residual ripple
Elimination of premature motor damage caused by high dv/dt, overvoltages, cable ringing and motor overheating
Improves bearing life time because of bearing currents caused by circulating currents
Complies with IEC 60034-17* requirements for general purpose motors
Optional with IP20 protective cover

Typical applications

HVAC applications
Pumps
Conveyors
Compressors
Elevators
Cranes
Medium voltage applications, deployed in front of the step-up transformer
Retrofit installations with motor drives
Motor drive with long motor cable
Motor drive with multiple motors in parallel
