DEFINITION

Classification: 310/316.02

Traveling wave motor:

(under subclass 316.01) Subject matter wherein two or more groups or piezoelectric elements lying along a driving surface expand and contract in repetitive cycles generating a mechanical output having a crest or high point which appears to move along the surface of the piezoelectric elements along a direction of travel (typically rotary or linearly) whereby a driven surface pressed resiently against the driving surface is carried along the direction of the crest or high point.
