Transient thermal analysis of flux switching PM machines

Flux switching permanent magnet (FSPM) machines bring together the merits of switched reluctance and PM synchronous motors. FSPM employs armature windings and PMs together in the stator region, therefore the proximity of the windings PMs makes a thermal model mandatory. In literature, thermal modeling of the FSPM is not addressed extensively compared to its electromagnetic modeling. With this aim, first a steady-state TEC model is created for a 3-phase 12/10 FSPM. Additionally, conformal mapping, in particular Schwarz-Christoffel, is used to increase the accuracy of the TEC model. Using Laplace transformation, the steady-state model is extended to a transient thermal model. Results are compared and validated by the finite element method.
