According to previous research on the creation of linear piezo-motors using the “shaking beam” principle the authors have proposed a new rotating type piezo-motor based on the same principle. The advantage of the current motor compared with analogues motors is shown. The proposed motor uses both actuator of longitudinal-torsion vibration and a wave motor. In this paper computer simulation by FEM analysis of the proposed system is given. The simulation results of modeling are confirmed experimentally. The authors used precision laser equipment for testing and measuring.
