| 摘要 |
<p>The invention concerns a motorised electromagnetic movement (1) for displacing and accurate angular positioning comprising a rotor-type mobile element and a stator-type fixed element, the rotor comprising a pin (3) mounted rotatable on itself, an arm (4) comprising at each of its two opposite ends a magnet (41, 41'), said arm being mounted integral substantially perpendicular in its balance point to said pin (3), said magnets (41, 41') being mobile along a rotation circle (61) whereof the centre corresponds to said pin (3), the stator comprising two magnetic field electrical generators (6, 6') arranged on the rotation circle (61), the virtual straight line (62 )joining the two generators not passing through the pin (3), the two generators being separated by 135° to 180° between them, preferably between 170° and 180° between them. The invention also concerns a use method. The invention is applicable in optics, a mirror (52) being integral with the rotation pin (3).</p> |
