In this study, an ultrasonic motor for a solid-state high resolution nuclear magnetic resonance (NMR) spectrometer has been fabricated and evaluated. In solid-state NMR analysis, it is necessary to rotate samples at a high speed and a high preciseness. The motor are composed of non-magnetic materials. The motor consists of two sector shaped vibrators. The diameter and the height of a probe unit including a sample case and the motor are 31 mm and 50 mm. The unit was unaffected by the magnetic field. The rotation speed was 1200 rpm when the magnetic flux density was 9.4T. Additionally, we have successfully obtained a solid-state NMR analysis of glycine. From this result, the motor can be applied to sample rotation of solid state NMR spectrometer.
