Micro SMES magnet configurations for reduced stray field applications

Reduced field coil configurations offer an attractive design alternative for small superconductive magnetic energy storage (/spl mu/SMES) systems. These commercially available systems are currently being used for improving the power quality in power conditioning sensitive processes. A reduced field design of /spl mu/SMES would allow its use in high-field sensitive environment. In this paper, proposed multiple parallel solenoids enclosed in one container with alternating field directions is presented and compared to a single solenoid. The parametric study covers stored energy, conductor volume, and overall magnet system dimensions. The efficiency of stray field reduction compared with the conventional single solenoid is also presented.<
