Abstract:To control the eddy current loss so as to enhance efficiency, an econimic and effective method for slotting a Terfenol rod was pointed out in literature8]. We put forward a simple method to caculate the mumber of slots needed to meet the demonds on the resonance frequency. An illustrating example offers results consistent with the discussions given in 8].
Keywords:Terfenol bar  Eddy current losses  Limit working frequency
