You can use the calculator in the post processor to integrate power loss density on specific volumes/areas to get the power loss in them.Maxwellv12中徒手畫圖形還是用對話框畫？v12中徒手畫還是用對話框畫圖形是可以選擇的，用F3/F4在兩種模式下切換。DCore lossF [9| eC0Definition: For laminated steel, 3 kinds of losses are considered. They are hysteresis loss, classical eddy current loss and excess loss. These losses are calculated by using the coefficients (Kh, Kc, Ke) derived from the loss graph provided by steel pany. f8Mu R Q_0 stranded coils have no power loss if not modeling every single strand (paraphrase of the previous statement)SimWe個(gè)人空間 bamp。 rotor bars in induction motor has power loss because of the eddy currentTOo v+S,^ U0 although it is not very mon to calculate eddy current in other auxiliary parts, but if there are some objects where it is necessary to do so, power loss will be generated4F2lSI!^w0 in most cases, eddy current effect in the sleeves holding the magnets in PM motor is considered, so there is power loss for the sleeve39。d a0 Definition: Any occasion that involves induced eddy current.3ohK}9B u0 Ohmic power loss (Joule loss)`:C8Mv v*~*Not
