Numerical investigation of properties of small size Axial Flux Permanent Magnet Motors

The paper is focused on numerical FEM analysis of axial flux permanent magnets (AFPM) motors dedicated for manufacturing by 3D printing. The machine has a topology of single stator - double rotor. Two types of such a machine are investigated: having two and ten permanent magnets located at each of rotor discs. The analysis is carried out as a 2D static and 3D transient. Results of analysis are magnetic flux density, induced voltage and electromagnetic torque. Comparative analysis is also presented in the paper.
