Technical Examples
A radial piezoelectric motor comprises a housing, a motor shaft rotatably mounted in the housing and a plurality of piezoelectric actuators inside the housing radially disposed about the axis of the motor shaft. The motor also includes circuitry for applying a voltage to the piezoelectric actuators to expand the actuators repeatedly and in succession and apparatus responsive to the repeated and successive expanding of the actuators for rotating the motor shaft.
