Magnetic field analyzis of Permanent Magnet Synchronous Motor
http://www.maplesoft.com/applications/view.aspx?SID=103042&ref=Feed
<p>In this study, I explore magnetic field numerical modelling of Permanent Magnet Synchronous Motor with Maple. Finite element method is well known and always implemented with FORTRAN, C and Matlab.</p>
<p>The model studied is simple and can be done analytically. I introduce here only the code MAFEM which is able to analyse more complicated structure of PMSM and where analytical solving of Poisson equation is difficult. By using Maple, I'm able to start from analytical equations like those of Maxwell and use some symbolic integrals and at the end do the numerical analysis by FEM. Triangular elements are used here to approximate the domain, but other type of elements can be used and I think it is more easy to implement with Maple than with Fortran or Matlab.</p><img src="/applications/images/app_image_blank_lg.jpg" alt="Magnetic field analyzis of Permanent Magnet Synchronous Motor" align="left"/><p>In this study, I explore magnetic field numerical modelling of Permanent Magnet Synchronous Motor with Maple.

<p>In this paper an analytical model for predicting the open-circuit magnetic field distribution in the air gap of iron-cored internal rotor with radial magnetization of surface mounted magnet and a slotless stator is presented. The model is extended to the prediction of the armature reaction field, back-emf and instantaneous torque produced by the 3-phase stator windings with fractional or integer slot per pole and per phase of iron-cored internal rotor. Analytical model can be adapted also for any type of windings. The results are in closed forms and provide a basis for comparative studies between existing permanent magnet (PM) machines and searching for new PM machines topologies. Predicted armature reaction field distribution, back-emf and instantaneous torque can be validated by comparing with corresponding finite element calculations.</p><img src="/applications/images/app_image_blank_lg.jpg" alt="Analytical Magnetic Field Modeling of Slotless Permanent Magnet Synchronous Motors" align="left"/><p>In this paper an analytical model for predicting the open-circuit magnetic field distribution in the air gap of iron-cored internal rotor with radial magnetization of surface mounted magnet and a slotless stator is presented.
