Traditional field-based methods such as Finite Element Analysis (FEA) for modeling Electro Mechanical Energy Converter (EMEC) are computationally inefficient, which in turn limits their application in drive system design. Moreover, multi-objective optimization worsens this shortcoming and imposes new limitations on computation time. However, FRM can significantly reduce the time of analysis by utilizing a small number of field solutions from FEA to establish the basis functions which are then used to reconstruct the magnetic field without losing accuracy.
FRM has already been applied to induction machines, linear induction machines, doubly fed induction generators and permanent magnet synchronous machines. Magnetic fields estimated from FRM for these EMECs have a good agreement with those obtained from FEA. FRM's feasibility and high efficiency in terms of computation time have been highlighted by its applications in variety of areas as follows,
>Torque ripple mitigation in PMSM
>Thrust force optimization in Linear Induction Machines
>DFIG design optimization
>Development of fault tolerant PMSM drives
An extended FRM is under development to address the magnetic saturation in Switched Reluctance Machines.
