Design, Modeling and Prototyping a Flat Switched Reluctance Machine for Direct‑Drive Systems
Majid Asgar,Hossein Torkaman,Ebrahim Afei 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.1
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.
