Developing a Very Fast and Accurate Model of Linear Sinusoidal Area Resolver Considering End Effects and Faulty Conditions

Similar to each electromagnetic device, resolvers' design and performance investigation through an accurate and preferably fast tool are necessary. On the other hand, due to the 3-D geometry of the sinusoidal area (SA) linear resolver, its performance evaluation and iterative design procedure is a big challenge, especially through 3-D time-stepping finite element analysis (3D-TSFEA) and common analytical methods. Accordingly, the following study suggests a hybrid linear resolver model to overcome the above challenges. The suggested hybrid linear model can precisely consider the longitudinal end effect and faulty resolver conditions. In addition, implementing the suggested hybrid model in MATLAB/Simulink gives the capability of some investigations, such as resolver condition monitoring alongside the drive control system. Verifying the above merits, including high accuracy and significant time saving of the suggested hybrid model, was shown by comparing its results with those of 3D-TSFEA and experimental measurements.
