| Abstract: | In order to improve the mechanical output performances of the traveling-wave type ultrasonic motor(USM),an optimal design method based on the energy indexes for the USM was proposed according to the force transform model of the ultrasonic motor contact surface between the stator and the rotor.The finite element model of the USM stator was established and the energy indexes under several different operating modals of the USM were computed.Based on the energy indexes,the effects on the vibration modals and th... |
