Piezoelectric inertia motors—also known as stick-slip motors or (smooth) impact drives—use
the inertia of a body to drive it in small steps by means of an uninterrupted friction contact. In …

Harmonic drives are profusely used in aerospace mainly because of their compactness and
large reduction ratio. However, their use in cryogenic environments is still a challenge …

Contactless bearings based on both permanent magnets and superconducting magnetic
levitation are interesting to avoid all the tribological problems associated with contact at very …

Contactless mechanical components are mechanical sets for conversion of torque/speed,
whose gears and moving parts do not touch each other, but rather they provide movement …

In this research permendur (49Fe-49Co-2V) and nickel were used to make a novel bimetal
actuator. The actuator consists of a main body and core with energizing coil. The main body …

First, attapulgite‐Fe3O4 magnetic filler (ATP‐Fe3O4) was prepared by using a chemical
precipitation method. Subsequently, graphite oxide (GO) was prepared through Hummer …

This paper describes the improvement of the performance of a long-stroke high-precision
positioning slider suitable for cryogenic environments due to the application of a set of …

In this work, the mechanical behaviour of a frictionless superconducting magnetic bearing
(SMB) is presented. The bearing is a thrust bearing composed of a YBaCuO …
