Common Mode Noise Suppression in Motor Drive Circuit

  • With high impedance in wide frequency band, common mode choke made of nanocrystalline soft magnetic material FINEMET® realizes high noise suppression effect.
  • FINEMET® common mode choke with high impedance contributes to size and weight reduction of EMC/EMI components.
  • Suppressing common mode noise will decrease bearing currents, that contributes to long lifetime of motors.
