“…large number of techniques have been developed for incorporating or coupling of hi-fidelity electric machine models in system simulation tools where hi-fidelity is taken to mean electric machine models beyond the standard fundamental harmonic dq models such as finite element models or magnetic equivalent circuit models [1][2][3][4][5][6][7]. System simulations are taken to mean simulations that may incorporate the control system behavior or power electronics.…”

This paper proposes a technique for rapid high fidelity finite element based synchronous machine models for use in system simulators. The computational efficient finite element procedure, CE-FEA, is used to construct harmonic flux linkage arrays for a range of current inputs. In the system simulator, a map is constructed relating rotor position as an input to relate instantaneous flux linkage and d and q axis currents. Using rotor position and flux linkages as inputs from the system simulator and interpolating the flux linkage map, the phase currents of the synchronous machine are determined. In the system simulation, the phase currents are modeled as dependent current sources. This technique allows for the modeling of space and time harmonics, saturation, and cogging torque within the system simulator without directly coupling the finite element solver. Three examples of system simulation results are shown for an interior permanent magnet synchronous machine.

This paper aims to define a minimum set of finite element solutions to be used in the design and analysis of saturated permanent-magnet motors. The choice of the finite element solutions belonging to this set is strictly associated with the classical d - q axis theory and it is described in terms of key points on the Flux-MMF diagram. When synchronous machine are considered, such a diagram has a regular shape, so that a huge reduction in finite element field solutions is possible with no loss of accuracy. It is also shown that the torque computed by using the d - q axis theory is almost independent of variation of the flux linkage with the rotor position. At last, the paper describes a technique in which few finite element solutions allow the identification not only of the average torque, but also the main torque harmonics. As a results, the torque behavior versus rotor position can be rapidly predicted

Interior permanent magnet motors equipped with a squirrel-cage rotor are receiving lately an increased interest. Defined as line-start, line-fed or hybrid synchronous-induction motors, such machines combine the advantage of the brushless permanent magnet motors, i.e. high efficiency, constant torque for variable speed, with the high starting capability of the induction motors connected directly to the supply system. This paper proposes a unified analysis of these motors, with an emphasis on how any possible configuration may be described by using symmetrical components and two equivalent fictitious machines: positive and negative sequences. The analysis is validated on a single-phase unbalanced and on a three-phase balanced line-fed interior permanent magnet motors.
