Abstract :
A lumped parameter magnetic circuit (LPMC) model is developed to predict the electromagnetic performance for Halbach magnetized permanent-magnet (PM) machine. The key of the LPMC model is to introduce a method, establishing equivalent Magnetic Motive Force (MMF) of every branches for Halbach magnetized PM machine. Comparing with the finite-element method (FEM), the LPMC method can reduce the total computational time greatly. Hence, it is used to calculate the flux linkage, back-electromotive force (back-EMF), and torque performance of Halbach magnetized PM machine. The effectiveness of the LPMC model is verified by comparing with two-dimensional (2-D) FEM and the experiments.
