Modal Analysis on Linear Ultrasonic Motor

Abstract:

As the expanding applications of linear ultrasonic motor, the demand for high-thrust linear ultrasonic motor in the aerospace and industrial robots is growing. Consequently, for a high-thrust linear motor, it’s stator model was established according to the actual structure of the motor stator and was also analyzed of the motor stator modal by the finite element method. The results show that the inherent frequency of vibration for the motor stator increases with the order, and corresponds with the vibration mode, by which was realized to work for the linear ultrasonic motor.
