Electric machines

 2D models of electric machines: permanent magnet and wound field synchronous machines, induction machines, switched reluctance machine. Download model archive (machines.zip) Browse individual model files and modification history

To run the models, open main.pro with Gmsh.

The models include:

• three permanent magnet machines: pmsm.pro and pmsm_cbmag.pro (two design variations of an eight-pole permanent magnet synchronous machine from GRUCAD, Universidade Federal de Santa Catarina, Brazil[1][2][3]), and lomonova.pro (another eight-pole permanent magnet machine [4])
• one four-pole wound field synchronous machine: wfsm_4p.pro[5]
• three induction machines: t30.pro (a simple induction motor with solid rotor from the TEAM workshop benchmarks[6][7]), im_3kw.pro (a four-pole induction machine [8][9][10]) and im.pro (a four-pole deep-bar induction machine [11])
• one switched reluctance machine: srm.pro[12][13]

All the models are solved using a 2D vector potential formulation, coupled with circuit equations if necessary. Motion is solved with the moving band technique, except for t30.pro which can also be solved using a velocity term.
