Ultrasonic motor for sample spinning of solid-state nuclear magnetic resonance spectrometer in high magnetic field

摘要

The aim of this paper is to realize a new sample spinning unit for a solid-state nuclear magnetic resonance (NMR). In the solid-state NMR analysis, a sample spinning in high magnetic field is an important function. We have designed and fabricated the sample spinning unit using a low-profile ultrasonic motor for high magnetic field. The unit could be driven in high magnetic flux at 9.4 T. Soli-state NMR analysis of glycine was measured using the unit. We have succeeded in applying the ultrasonic motor for solid-state NMR analysis.
