Abstract (en)
[origin: WO2018149714A1] The invention relates to a piezoelectric motor having a stator (1), a rotor rotating about a rotational axis (5) and at least one piezoelectric element (20, 21) driving the rotor and maintained by the stator (1). The aim of the invention is to increase the mechanical reliability and performance levels of a piezoelectric motor. The aim is achieved in that the piezoelectric element (20, 21) is mounted in an oscillating housing (8) which oscillates with respect to the stator (1) about the pivot axis (16).
