Abstract
A galvanometer drive with a rotor that is rotatable about an axis of rotation and includes a magnet, and a stator unit that surrounds the rotor and includes a coil, the rotor being supported by two bearings, at least one of which is a floating bearing, such that the rotor can perform a rotational movement relative to the stator unit about the axis of rotation. A radial movement limiting device is adapted to limit the radial movement of the floating bearing with respect to the stator unit.
Claims18
A galvanometer drive comprising:
- a rotor which is rotatable about an axis of rotation and which comprises a magnet, and
- a stator unit which surrounds the rotor and which comprises a coil,
- the rotor being supported by two bearings, at least one of which is a floating bearing, in such a way that it can perform a rotational movement about the axis of rotation relative to the stator unit,
- characterized by a radial movement limiting device, which is adapted to limit the radial movement of the floating bearing with respect to the stator unit, wherein a ratio of radial stiffness to axial stiffness at the floating bearing is greater than 10.
