The major goal of this thesis was to design and develop an actuator, which is capable of producing translational and rotary output motions in a compact structure with simple driving conditions, for the needs of small-scale actuators for micro robotic systems.Piezoelectric ultrasonic motors were selected as the target actuator schemes because of their unbeatable characteristics in the meso.

A doubly excited, doubly salient, concentrated winding type of rotary actuator structure is examined.Neglect of iron-member reluctances predicts a flat torque characteristic over the normal limited range of movement.In practice, a flat characteristic is not achieved.The reason for this is shown, by analysis and measurement, to be due to the significance of the iron reluctances both before.
