| Abstract [eng] |
The system is investigated, in which micrometric displacements are obtained by mechanical means and nanometric displacements - by variation of magnetic flux directed through magnetostrictive material terfenol-D. The permanent magnet is used as a magnetic flux source. A parallel branch to terfenol-D rod’s magnetic circuit branch enables to form nanometric and micrometric displacements separately and independently. Nanometric displacements are formed by variation of the air gap at the parallel branch. It is recommended to shield the air gap by ferromagnetic screen. In this case the dependence of magnetic flux through the terfenol-D rod versus the air gap is practically linear. |
