| Popis: | This paper presents a fast and efficient methodology to compute the efficiency maps of PMSMs by means of magneto-static finite element analysis and direct-quadrature (dq) electrical modeling. The algorithm uses the magnetic flux density distribution to predict the time evolution in each region, thus performing a harmonic decomposition to compute iron losses. On the other hand, from the magneto-static analysis, by analyzing other parameters such as the electromagnetic torque and the flux linkage, the overall motor performance using direct-quadrature axis model is determined. The computational burden of this method is less compared to the conventional method based on time dependent simulations. Therefore, this methodology is well suited to deal with optimization methods. Finally, the method is validated by using public experimental data from the PMSM of the Toyota Prius 2004. |
