Abstract :
This paper presents the performance evaluation of two different size 6 slots and 4 poles brushless DC permanent magnet motor. These devices were simulated and tested in order to obtain efficiency, iron losses, copper losses, and shaft power. The simulation was done using a program called Finite Element Method Magnetics (FEMM) and a script based on the programming language Lua. The electrical steel sheet was characterized through an Epstein experiment, and the results were applied to improve the simulation. Furthermore a dynamometer was used to check the method applied. It was observed that the calculation method allows predicting the motor performance with reasonable precision.
