| Research Abstract |
In this study, we have developed an ultrasonic linear motor that incorporates two transducers at an acute angle. We focus on developing actuators for use in a bedsore prevention bed. The first fabricated motor had a flow in that the driving frequency of the motor was not synchronous with the resonant frequency of the transducers. Furthermore, the rigidity of the structure was low. Therefore, the motor did not generate large power. By solving these problems, a maximum thrust of 40 N and a no-load speed of 267 mm/s were obtained.
