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, motor overheating, and eddy current losses
  • Improves bearing life time because of bearing currents caused by circulating currents
  • Complies with IEC 60034-17* and NEMA-MG1 requirements for general purpose motors
  • Optional with NEMA 1 protective cover

Typical Applications

  • HVAC applications
  • Pumps
  • Ventilators
  • Conveyors
  • Compressors
  • Elevators
  • Cranes
  • Medium voltage applications, deployed in front of the step-up transformer
  • Retrofit installations with motor drives

*    General purpose four-pole (1500 r/min) AC induction motor rated 400 V/50 Hz.
**  General purpose four-pole (1500 r/min) AC induction motor rated 480 V/50 Hz.
*** Exact value depends on the motor cable length and type, switching frequency and further stray parameters of the system.

Required drive settings

Ensure the drive’s switching frequency is set to the required minimum switching frequency (see filter selection table). The mode of operation must be “scalar” (V/Hz) with a fixed switching frequency. Check the drives manufacturer manual whether special settings are necessary. In any doubt contact the drives manufacturer. CAUTION: If the motor drives settings are not correct the filter may be damaged.
