Modelling of interior permanent magnet synchronous motor in software package Motor-CAD

Izrađen je elektromagnetski i toplinski model sinkronog motora s unutrašnjim permanentnim magnetima Končar IPM180. Model je izrađen pomoću podataka iz projektne dokumentacije i mjerenja na prototipu stroja. Iz mjerenja je zaključeno da se stroj pregrijava u trajnom nazivnom opterećenju zbog nedovoljnog hlađenja na zrak. Model stroja uspoređen je s strojem redizajnirane geometrije statora i vodnim hlađenjem. Za redizajnirani stroj izrađen je proračun vršnih i trajnih karakteristika pomoću Motor-CAD alata „Lab“.An electromagnetic and thermal model of synchronous motors with internal permanent magnets Končar IPM180 was developed. The model was created using data from project documentation and measurements on the prototype of the machine. It is concluded from the measurement that the machine overheats in continuous rated load due to insufficient air cooling. The original model was compared with the model of redesigned stator geometry and water cooling. For the redesigned machine, the calculation of peak and continuous characteristics was made using the Motor-CAD tool "Lab"
