Fast sizing and simulation of multipole radial flux permanent magnet synchronous machines

This paper provides an automatic tool for the sizing, calculation, optimization and simulation of multipole radial flux permanent magnet synchronous machines (RPMSM). Only four parameters must be defined to obtain the machine: output power, rated voltage, frequency and number of pole pairs. firstly, geometric, electric and magnetic characteristics are obtained. Secondly, an accurate calculation of the sized machine is done. In order to check the influence in machine performance any variable can be modified in optimization loops. All this procedure has been implemented using MATLAB
^reg
obtaining different prototypes in a very short time, reducing significantly RPMSM design process. The obtained geometry is exported to a finite element method software where the geometry, mesh, material characteristics and electrical circuit are automatically generated. Finally all the procedure has been contrasted and validated through the construction and testing of a laboratory prototype.
