Optimal design of Interior Permanent Magnet Motor with wide flux weakening range

Increasing the Constant Power Speed Range (CPSR) and economical design are the main concern for designers. In this paper a new optimal design of the interior permanent magnetic motor for traction application is proposed. The magnet volume has been minimized and CPSR has been wide enough for traction applications. The new idea of this paper is combination of the PM segmented and using nonconventional air bridges in one design. The optimization process has been done using Genetic algorithm (GA). Verification of simulation results has been done using Finite Element Method (FEM)
