ASM INNOVATIVE PROJECT
AIM
To calculate Rotating Losses in a Surface Mount Permanent Magnet
Motor using several Finite Element Analysis runs as well as plot the
curves of the variation of each type of loss with speed and represent
the power loss density on a heat map.
SOFTWARES USED
1) FEMM (Finite Element Method Magnetics) is a suite of
programs for solving low frequency electromagnetic problems on
two-dimensional planar and axisymmetric domains. The program
currently addresses linear/nonlinear magnetostatic problems,
linear/nonlinear time harmonic magnetic problems, linear
electrostatic problems, and steady-state heat flow problems
2) MATLAB (an abbreviation of "matrix laboratory") is a proprietary
multi-paradigm programming language and numeric computing
environment developed by MathWorks. MATLAB allows matrix
manipulations, plotting of functions and data, implementation of
algorithms, creation of user interfaces, and interfacing with
programs written in other languages.
3) OctaveFEMM - To aid in the use of FEMM from Matlab, a
toolbox called OctaveFEMM is available. This toolbox
implements Matlab commands that subsume the functionality of
Lua using equivalent Matlab commands, in a similar way to the
fashion that MathFEMM works with Mathematica. Using the
toolbox, all details of the ActiveX interface are taken care of in a
way that is completely transparent to the user.
