摘要： An ultrasonic motor includes a stator. The stator includes a seat and a driving unit. The driving unit includes a generally semi-elliptical driving mechanism formed integrally with the seat, and two spaced-apart piezoelectric actuators disposed between the seat and the driving mechanism. Each of the piezoelectric actuators has a first end abutting against the driving mechanism, and a second end opposite to the first end and abutting against the seat.
