Abstract

A resolver is a position sensor used for rotational or linear positioning. The optimal design of the resolver needs an accurate and computationally fast model. Such a model for the linear resolver must also be able to take the longitudinal end effect into account. Therefore, in this paper, an analytical model based on the subdomain method is proposed for the linear resolver. The presented model, not only considers the longitudinal end effect of the stator and mover, but also takes the cores’ slotting effect into account. The results of the proposed model are verified by comparing them with the results of the finite element analysis and the experimental measurements on the sensor’s prototype.
