This work presents a new analytical modeling method of electrical machines with a focus on Permanent Magnet Synchronous Motors. The goal of this work is to establish a platform for simulation and optimization of synchronous motors considering the spatial distribution of flux density in all its parts. The dynamic motor behavior is emulated with a quasi-static model. Based on this model, all other motor parameters are calculated and presented as mathematical functions of time and rotor position. The spatial harmonic model of the motor facilitates a deeper understanding of motor behavior. The adaptive algorithm introduced here can be modified based on the results obtained from finite element analyses. The compliance of the analytical model to finite element calculations is the main goal of this work.
