Axial-flux permanent magnet machines are popular and widely used for many applications due to their attractive features such as light weight, low noise, high torque, robust and higher efficiency due to lack of field excitation. The main essence of this paper is to perform slotted and slotless axial-flux permanent magnet synchronous generator design based on theoretical sizing equations and then finite element analysis is reinforcement in order to get a more reliable and accuracy machine design. A comparative study of machine design and performances over the same rating but different configurations i.e., slotted and slotless are also discussed. And then, finite-element method (FEM) software was made for the slotted stator and slotless stator (AFPMSG) in order to compare their magnetic flux density and efficiency. The AFPMSG topology considered in this paper is a three-phase double-rotor single-stator topology with 16 pole-pairs, 2kW rated power and 188 rpm rated speed.

The Magnetic Field

Due to its compact construction and high power density, the axial-flux permanent-magnet (AFPM) machine with coreless stator has obtained more and more attention and interest from researchers. For an AFPM machine with coreless stator, the axial magnetic attraction force may cause the rotors’ deflection and affect the machine’s reliability. In this paper, the magnetic field and the rotor mechanical strength of a coreless stator AFPM machine are studied. Finite-element method and analytic method are both used to calculate the axial attraction magnetic force between the two rotor discs. Structure finite-element analysis is used to simulate the maximum stress and deflection due to the axial magnetic force. The research is very significant to the power density elevation of the AFPM machine.
