In this paper a novel method of the Ant Colony Optimization algorithm for rotor position estimation in Switched Reluctance Motors is presented. The data provided by the initial assumptions is one of the important aspects used to solve the problems relative to an Ant Colony algorithm. Considering the nature of a real ant colony, it was found that the ants have no primary data for deducing which is the shortest path in their initial iteration. They also do not have the ability to see the food sources at a distance. According to this point of view, a novel method is presented in which the rotor pole position relative to the corresponding stator pole in a switched reluctance motor is estimated with high accuracy using the active and inactive phase parameters. This new method gives acceptable results such as a desirable convergence together with an optimized and stable response. To the best knowledge of the authors, such an analysis has not been carried out previously.

In this paper, a fat-type 24 by 16 SRM, is considered for the application of direct-drive washing machine. Firstly, the structure is introduced and using the nonlinear equivalent circuit, the researchers present a design for the SRM. Then, using the three-dimensional fnite element method, the electromagnetic characteristics of the proposed confguration are analyzed to evaluate the motor’s performance. The motor prototype is fabricated and tested experimentally to authenticate the theoretical and simulation analysis, and subsequently to prove the applicability. Finally, the performance of this proposed motor is compared with an SRM that has the same condition. Since a direct drive motor does not require a reduction gear, the drive system can be made simple without harmonic gears, and therefore it can be used in high-precision, more reliable, and low cost appliances.
