Add-on Sine Wave Module for Common-mode Voltage Improvement


Add-on Sine Wave Module for Common-mode Voltage Improvement

  • Additional module for use with FN5420 or FN5020 sine wave filters
  • Reduction of common-mode interferences on motor cables
  • Improvement of EMC environment
  • Elimination of motor bearing damages
  • Possibility to use very long unshielded motor cables
  • Improvement of system reliability

Features and Benefits

Add-on output filter module for the use with FN5420 or FN5020 sine wave output filters with corresponding current rating
Elimination of premature motor failure caused by bearing damage
Eliminates interference propagation towards components or conductors in the vicinity
Restricts pulse currents to ground and hence limits leakage currents in the PE
Allows the use of extremely long unshielded motor cables without causing radiation problems (EN 55014, MDS clamp)
Reduces the required EMI suppression efforts on the line side
Allows the use of lower rated drives with long motor cables due to lower losses in the IGBTs and in the motor cable
Suitable for rotating fields up to 600 Hz

Typical Applications

Motor drive applications with extremely long motor cables
Motor drive applications with unshielded motor cables
Motor drives and motors in high-speed applications
Mission critical applications
Applications with multiple parallel motors
Retrofit of motor drives into existing installations with old wiring and motors

Important note

FN5030 are additional common-mode modules. They can NOT work alone! FN5030 have to be operated downstream of a regular (symmetrical) sine wave output filter. Possible combinations are FN5020/FN5030 for motor frequencies up to 600 Hz, or FN5420/FN5030 for max. 60 Hz. For additional information please consult the Schaffner application note "Sinus Plus - New Output Filter Concept for Power Drive Systems"
