Abstract: A novel linear ultrasonic motor operating under two sixth-order bending modes which were orthogonal in space was designed. Its drive principle as well as the trajectory of particle on stator surface was analyzed. Besides,the fixation of the stator and way of applying the preload were fabricated. The stator manufactured has a length of 108 mm,a diameter of 20 mm and weight of 230 g. In the case of the driving signal of 300 V （peak to peak） and 32 kHz,the motor can reach a maximum speed of 433 mm/s,a maximum thrust of 18 N and the ratio of thrust to weight 7.9:1.
