The invention provides a multi-ceramic excitation standing wave type linear ultrasonic motor based on a cross-type stator structure. The multi-ceramic excitation standing wave type linear ultrasonic motor comprises a piezoelectric ceramic group, a metal elastomer and a driving foot group. The piezoelectric ceramic group includes an upper surface piezoelectric ceramic, an upper-right-end piezoelectric ceramic, a lower-right-end piezoelectric ceramic, an upper-left-end piezoelectric ceramic and a lower-left-end piezoelectric ceramic. The upper surface piezoelectric ceramic is attached to the upper surface of the metal elastomer being a cross-shaped metal elastomer. The metal elastomer includes an elastomer middle part and protruding parts; the protruding parts are arranged at the middle parts of the end surfaces of the two ends of the elastomer middle part; and the elastomer middle part and the protruding parts form a cross-shaped structure. Compared with the traditional structure of pasting the piezoelectric ceramic on the upper surface of the elastomer separately, the multi-ceramic excitation standing wave type linear ultrasonic motor enables the vibration amplitude of the stator to be increased; and the multi-ceramic excitation standing wave type linear ultrasonic motor has advantages of small size, compact structure, and large motor output.
