The inductance profile plays an essential role in the verification of the design and performance of permanent magnet machines. Various inductance measurement methods have been widely introduced and discussed for permanent magnet machines and switched reluctance motors. These methods have something in common and some of the measurement methods for switched reluctance motors are also suited for the inductance measurement of permanent magnet machines. In this paper, based on the present methods, a simple but accurate method is introduced for measuring the nonlinear inductance profile of permanent magnet machines. A single phase surface mounted permanent magnet transverse flux machine is chosen as an application example due to its simple single-phase structure with concentrated winding, which may simplify the analysis and make the proposed method more straightforward. The proposed method is verified by experiment and compared with 3D FEM result.
