This paper analyzed and calculated electromagnetic field and counterbalance force between the permanent magnet thrust plate for a novel permanent magnet axial thrust balance structure in canned motor pump using a numerical method of Ansoft software. Then constructed permanent magnet axial thrust balance experiment device and detected the characteristics of repulsion and attraction which make up of axial balancing force between the axial thrust plates. The numerical simulation is very consistent with experimental results and this shows the validity and accuracy of the study. So the paper provided basically conditions for further researching, designing and developing novel permanent magnet axial thrust balance device of canned motor pomp.
