ACTUATOR COMPRISING A ROTATABLE MAGNET BODY; ACTUATOR UNIT COMPRISING THE ACTUATOR AND A CONTROL SYSTEM; MAGNETO-OPTICAL DEVICE COMPRISING THE ACTUATOR, AND SCANNER COMPRISING THE ACTUATOR

摘要

The invention relates to an actuator comprising a permanent magnet body (1) and coil means for cooperation with the magnet body.The magnet body is rotatable about an axis of rotation (7) between, for example two, stop positions The coil means exclusively compriseat least one active coil section (9a, 1la) of an electrical coil, which coil section extends parallel to the axis of rotation of the magnet bodyand substantially faces a magnet pole in a stop position of the magnet body.
