• Resumen

  • The main purpose of this paper is to discuss ways in which magnetic performance of electromechanical transducers can be simulated accurately using a series of finite‐element models. Of particular interest is the usage of multivariable interpolation techniques which enable significant reduction of the number of finite‐element computations necessary to fully model all relevant cases. This is particularly important in the case when a shift of the zero position of the coil occurs. Moreover, this type of modelling provides a good insight into the physical behaviour of the device and aids understanding of its performance characteristics. Finally, the paper presents briefly how a significant reduction in harmonic content has been achieved by improving the linearity of the magnetic circuit. These improvements have been confirmed experimentally.
