A novel cylindrical ultrasonic motor easy to be fixed is proposed in this article. There are threaded holes on the bottom of stator used for fixing, distinguishing it from other cylindrical stators. The bottom is machined as a round lug boss. Its radius is smaller than the inner radius of the stator in order not to affect the excitation of vibration mode. The finite element analysis was accomplished to verify the working principle. Based on the analysis, a prototype was fabricated and measured. The mechanical output characteristics were obtained by experiments. The maximal velocity of the proposed motor is 170 r/min at the operating frequency of 31.6 kHz.
