Abstract

A surface acoustic wave (SAW) linear motor, which is a kind of ultrasonic motors, has many merits such as thin structure, large force, high speed, precise positioning and so on. On the other hand, wear is one of problems in the motor due to friction drive principle. Diamond-like carbon (DLC) films have been recognized as a wear resistant material. In this research, segment structured DLC films are focused to avoid the DLC property of easy damage. Installation of the films to friction surface of the motor is reported. Measurement result of its driving characteristics is also described.
