【Abstract】 To calculate the parameters of Powerformer,a new type of high voltage generator,the finite element method is proposed in this paper.The slot leakage reactance,end region leakage reactance and armature reaction reactance of Powerformer are calculated with FEM and compared with the results calculated by traditional electrical machine design method.The result shows that armature reaction reactance can be calculated by traditional electrical machine design method;leakage reactance of semicircular slot can be determined by round-shape slot and rectangle slot leakage reactance;and FEM is more suitable for end region leakage reactance calculation.更多还原
