Charakterystyka magneto-mechaniczna silnika bezszczotkowego o wzbudzeniu od magnesów trwałych o sterowaniu trapezoidalnym

In the paper the algorithm of computing magneto-mechanic characteristic has been presented. The model of BLDC motor with consant magnets on the rotor, suplied by 3-phase source have been performed by ANSYS and Flux 2D programs using FEM Method. In the simulation the dependence on the feedback magnetic circuits, electromagnetic torque, currents, and angel of rotor rotation has been taken into consideration. It was done in two parts: – by creation model of machine, and – by computing magneto mechanic characteristic. All results the simulations have shown on the graphic diagrams.
