A piezoelectric motor includes a piezoresonator body (3) having opposing front and back surfaces and opposing first and second end surfaces. The front (17) and the back (18) surfaces are substantially parallel to first (15) and second (16) longitudinal axes of the piezoresonator body. The end surfaces (2) are substantially perpendicular to the first longitudinal axis and substantially parallel to the second longitudinal axis and are separated by a length (L) of the piezoresonator body. The motor also includes at least one common electrode (6) disposed on the back surface and at least 6n excitation electrodes (7-12) disposed across the front surface in two symmetric rows extending along L, where n is an integer ≧1. In the motor, the piezoelectric body has an nth order longitudinal vibration frequency (ν1) along L and a 3nth order bending vibration frequency (ν2) along L, and where ν1 and ν2 are substantially equal.
