“…When the FEM is used to analyze PMASynRM, complicated magnetic circuit structure and various boundary conditions of the motor can be considered, and the results are accurate. However, FEM is not suitable for making a choice among a wide range of analysis methods due to its consumption of much time and internal memory [3]. Therefore, FEM is usually used in the final verification stage of design models or analytical models [4]- [6].…”

“…A MEC model for Synchronous motor incorporating moving air gap and cross-coupled saturation effects proposed in [13]. In article [3], the iterative magnetic circuit calculation is used to deal with the saturation effect of iron core. The lumped magnetic circuit model was extensively used for permanent magnet machine, which derived analytically the air-gap field distribution, average air-gap flux density, and leakage fluxes [4], [14]- [19].…”

In this paper, the equivalent reluctance network model (ERNM) is used to calculate the magnetic circuit of a permanent magnet-assisted synchronous reluctance motor (PMASynRM) and calculate no-load air-gap magnetic field and electromagnetic torque. Iteration method is used to solve the relative permeability of iron core. A novel reluctance network model based on actual distribution of the magnetic flux inside the motor is established. The magnetomotive force (MMF) generated by armature winding affects the relative permeability of iron core, which is considered in the calculation of ERNM to improve the accuracy when the motor is under load. ERNM can be used to measure air-gap flux density, no-load back electromotive force (EMF), the average value of motor torque, the armature winding voltage under load, and power factor. The method of calculating the motor performance is proposed. The results of calculation are consistent with finite element method (FEM) and the computational complexity is much less than that of the FEM. The results of ERNM has been verified, which will provide a simple method for motor design and analysis.
