Development of a Magnetostrictive Linear Motor for Microrobots Using Fe-Ga (Galfenol) Alloys

This paper presents a unique magnetostrictive linear motor using Fe-Ga (Galfenol) alloys. The actuator is driven by a novel self-propelling mechanism that takes advantage of friction and inertial force. We describe in detail the driving principle and simply analyze it. We also present several experi...
