KEB dV/dt filters reduce the peak voltage levels seen by the motor in VFD applications. dV/dt chokes help protect the motor insulation and increase operating lifetime by reducing motor heating.
dV/dt Filters - Motor Chokes
KEB’s dV/dt chokes do not skew the VFD’s motor model or negatively affect motor performance. They can be used with either PM or Induction Motors.
KEB dV/dt filters can be operated safely and effectively with high output frequencies from the drive – up to 16kHz carrier frequency.
Our dV/dt motor chokes have the secondary benefit of reducing EMI emissions (>250kHz range) from the VFD output.
