The purpose of this paper is to derive the geometry-based equations for inductances which are used in circuit theory analysis of synchronous reluctance motor (SRM). The analytical approach is used to obtain the equations which describe geometry dependent magnetizing inductances of SRM. The external electric circuit connected with the finite-element model of the SRM geometry allows the study of almost any of the electric and magnetic properties of the machine. The finite-element models coupled with an electric circuit is used to evaluate the motor performance at various asynchronous speeds.

The paper outlines a case study on optimal control of a brushless direct-current (BLDC) motor as a part of an Integrated Starter-Generator and torque Booster (ISGtB). The main scope of the introduced research work is the optimization of the BLDC motor torque characteristics. Two approaches for the optimization of the torque characteristics are discussed, the flux-weakening method and a modification of transistor conduction angle. Simulation and experimental results fully confirm improvements in the starting procedure of the hybrid propulsion system attained by the proposed control algorithm.

The aim of this paper is to present parametric nonlinear reluctance model of outer rotor permanent magnet transverse flux machine (TFM). Main and leakage magnetic flux paths of TFM are studied and modelled with reluctances using mean length and cross area approximation which divide the model into simple solids. General propose circuit simulator is used to solve the model. The main goal of the model is to provide the results of machine performances with sufficient accuracy and quick enough to use them in optimization procedures.
