Notes:
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.
