Abstract
Abstract A non-contact positioning device is composed of a driven body (1) formed by a magnetic substance which is the subject of positioning, and a driving body (3) constructed with electromagnets (5, 7, 9, 11, 13, 15, 17, 19) which support the driven body (1) without contacting it. The driven body (1) is formed as a simple polyhedron. The electromagnets are arranged facing each of the multiple faces of the simple polyhedron. This non-contact positioning device is constructed to adjust the position of the simple polyhedron by controlling the supply of current to the electromagnets.
