Abstract
Precise simulation of magnetic field in the air gap is necessary to Predict of electromagnetic performance of permanent magnet machines. In this paper an analytical approach is proposed to calculate the magnetic field of slot-less Axial flux permanent magnet machine. Finite element method is the most precise method for magnetic calculation in the air gap although because of its low speed calculation is not appropriate for parametric and optimization studies. In this paper, an efficient analytical method is used to parametric studies on magnetic field in the air gap in case of no-load operation. By applying above mentioned method with high analytical speed, flux density in the middle of air gap is predicted and then induced voltage is calculated. Result of proposed analytical method is compared with 3-D FEM simulations that are reached from Ansys-Electronics software. These results are in the form of Quasi-3D.
