Especially inductances affect the starting process significantly. This paper compared the effectiveness of fluxlinkage method and definition method using finite element analysis, and also conducted prototype tests to verify the calculation results. The contribution of damping winding in steady and transient inductance was analyzed, and verified by prototype experiments.
