Abstract :
A standing wave rotational motor was made by using PMS-PCS-PZT ceramics. The dynamic characteristics and equivalent circuit of the motor were studied theoretically and experimentally. Using the finite element method, the vibration modes of a longitudinal-torsional coupler of a standing wave motor were analyzed. With improvement of the coupler construction, the rotational speed of the motor is increased compared with the original one. The typical values of this motor are 270 r.p.m. with no load. The diameter of the stator is 32 mm. Its resonance frequency, operation voltage and largest torque are 30 KHz, 24 V and 10 Kg-cm, respectively
