A multi-degree-of-freedom spherical rotor piezoelectric actuator with flexible stator supports and adjustable preloading

Multi-degree-of-freedom spherical rotor piezoelectric actuators require multiple stators to maintain stable contact with a curved rotor, making their performance sensitive to nonuniform preload. This paper proposes a spherical rotor piezoelectric actuator comprising three symmetrically arranged traveling-wave stators,...
