Abstract

The stator geometries of ultrasonic traveling wave motors for high torque were investigated. In the disk-type motor, the piezoceramic excitation is inside the nodal circle and the friction contact zone is outside the nodal circle so that high output torque can be expected. By using piezoceramic rings of 90 mm outer diameter and a vibration mode with one nodal circle and 11 nodal lines a stator diameter of 112 mm was realized. A ring-type stator with 98 mm outer diameter was build and used for prototyping a new traveling wave motor. The design and optimization of the stator geometry are discussed.
