A new mini ultrasonic motor with metal bar and piezoelectric plate hybrid as a stator has been studied. Four piezoelectric plates are bonded to four sides of the metal bar. The metal bar is made of brass and the piezoelectric plates are made of PZT-4. The polarization direction is vertical to the piezoelectric plate. Compared with the cylindrical type of the motor, the square cross-section motor makes polarization more sufficient and signal wire easier to be welded. In this paper, the modal and harmonic analysis of the stator were performed by using FEM. The resonance frequency of the motor is about 100 kHz, the no-load revolution is above 6000 r/min and maximum torque is about 60 uNm. This new mini ultrasonic motor is of potential applications.
