Performance optimization of single crystal ultrasonic motors via a spliced stator: A novel design approach

Year: 2025

Type: article

Abstract: This study proposes a novel design for single-crystal ultrasonic motors (SCUSMs), which solves the problem of inconsistent circumferential output performance of SCUSMs by spliced piezoelectric single-crystal rings. The equivalent physical parameters of the optimized cutting structure were calculated based on Euler rotation theory. The stator model was simulated using finite element analysis, and the resonance frequency and amplitude were obtained from the simulation. A dynamic model derived from the principle of energy variation was used to further evaluate the output performance of the SCUSM. The calculation and experimental results show that the SCUSM exhibits good torque consistency along its circumference.
