Line start permanent magnet synchronous motor (LSPMSM) is a super-premium efficiency class motor with features of squirrel cage induction motor (SCIM) and permanent magnet synchronous motor (PMSM). This paper presents a reluctance network (RN) based analytical approach to determine the starting and steady-state performance of LSPMSM. The design parameters such as back electromotive force (EMF) and d-q axis inductance are calculated using the linear RN with a saturated flux bridge. Then the parameters are used in the analytical dynamic model to observe the machine performance. The objective of this study is to have a fast parameterized model to observe the effect of design variables such as rotor magnet and rotor bar dimensions on the motor performance. To validate the proposed technique, studied LSPMSM is also analyzed using the 2D finite element method (FEM).
