Eddy current loss of containment shell of high-speed magnetic driving pump

In order to quickly and accurately study the effects of containment shell material on the eddy current loss of high-speed magnetic drive pump, containment shells using materials TC4 and 1Cr18Ni9Ti were simulated using ANSYS software. The numerical results of eddy current loss were compared with those of experiment. The comparison results showed that, the eddy current loss generated by 1Cr18Ni9Ti was 2.26 times more than that of TC4 when other parameters were the same. The numerical results were in agreement with that of experiment, thus the credibility of numerical simulation eddy current loss was proved. Besides, it was also proved that TC4 was an ideal material for containment shells of magnetic driving pump.
