This paper investigates and compares the inductance evaluation methods for interior permanent magnet synchronous motors (IPMSM). Three major finite element methods will be discussed. First, their detail calculation processes are presented as well as their fundamental principles. Not only the results, but also their solving method, computation time and complexity are compared. Then, the discussion on the inductance classification is derived, and finally the calculated results are verified with a series of experiments. The investigation of the calculation methods and the comparison of the evaluated results will be helpful to choose the appropriate inductance calculation method for IPMSM.
