Abstract:The inertial linear ultrasonic motors have disadvantages, such as, small output forces and unstable structures. However, their output force and structural stability can be improved by modifying vibration modes of their structure. Here, a new structural design of an inertial linear ultrasonic motor was proposed. A rectangular plate structure was adopted for the motor to use its bending vibration modes. Then, the working principle of the motor was analyzed and the vibration of the stator was simulated and analyzed with ANSYS workbench software. Finally, the inertial linear ultrasonic motor was designed and manufactured. Tests of its prototype indicated that the motor has a wider working frequency range and its operation is stable; when the working frequency is 23.6 kHz, the maximum operation speed of the motor is 197 mm/s; when the working frequency is 23.2 kHz, the maximum thrust force of the motor is 7.3 N; the driving direction of the inertial linear ultrasonic motor has an abrupt change at a certain frequency point. © 2017, Editorial Office of Journal of Vibration and Shock.
