Improvement of the performances of line start permanent magnet synchronous motor with flux barrier in the rotor

Design of permanent magnet rotor for LSPMSM with inherent starting torque is the prime consideration for the designer. Presence of short circuiting flux for any kind of the PMSM reduces the starting as well as the steady state performances by reducing the air gap flux density. A new Permanent Magnet rotor with high reluctance flux barrier has been proposed in this paper. The model has been developed and simulated using Maxwell 2D. Two dimensional Finite Element analysis was done for magnetostatics and the transient analysis. The experimental prototype has developed, tested and the results thus obtained have been validated with the simulated results.
