tehran 0 Report post Posted July 23, 2019 what is the multi static? what is the torque that calculated when we simulate a E Motor and using multi static scenario for rotor? please help me Best Regards. Quote Share this post Link to post Share on other sites

Alejandro Rodríguez 12 Report post Posted July 25, 2019 Hello Tehran, Actually, the multi-static kinematic model, the moving part of the device is not moving. The computation of the electromagnetic field is carried out for various relative positions of moving and fixed parts, chosen in the scenario. This model performs a set of Magneto Statics computations. Therefore, computation of the electromagnetic field is not the same used in real moving mechanical sets, since it does not take into consideration the dynamic equation. Use this model is equivalent to run a parameterized study where the position of the moving part is a varying parameter, that means that the variation in rotor position should be established in the scenario definition -> control of parameters. The torque calculated in this way is equivalent to the torque experimented by the rotor as a function of its position (ANGPOS_ROTOR ), so the concept is the same that using a rotating mechanical set at imposed speed and the results should be quite close. Anyway, I strongly advise you to use imposed speed instead, since dynamic equations are more accurate that magneto static ones when movement is involved.
