A novel bonded type longitudinal-torsional piezoelectric motor was presented, including the stator, the rotor, the preloading system, etc. The stator was particularly slotted to form a structure with multi vibrators. The vibrator was constituted by the metal substrate and piezoelectric ceramics, which were pasted on the outer surface of the metal substrate. It was useful to simplify the motor structure. Through reasonable adjustment of the designed parameters, the resonant frequencies of the first longitudinal vibration model and the second torsional vibration model of the stator were adjusted as close as possible. Meanwhile, all the vibrators were under the resonance state, which is beneficial to improve the efficiency of the motor. To evaluate the overall performances of the designed motor, the finite element contact model was established to research the contact characteristics of the stator and the rotor. Through the analysis and solving of the static and transient contact process, pressure distribution of the contact areas, contact state, sliding distance, and etc. were all obtained under the condition of no-load. Besides, the speed curve and the output performance of the motor were both acquired. The results of contact analysis show that this USM is multi-surface contact mode actually. Analysis results also show that the contact pressure is not local concentration and sliding happens at the contact areas. Finally, according to the designed parameters, a prototype motor was fabricated and then the theoretical analysis was verified by experiments.
