Abstract:
A galvanometer drive particularly useful for a deflection unit includes a rotor that is rotatable about a rotational axis, the rotor formed in at least one section by a permanent magnet. A stator surrounds the permanent magnet, the stator including a coil. The permanent magnet includes at least two magnetic layers and at least one electrically insulating intermediate layer arranged between the two magnetic layers. A method for manufacturing the rotor for the galvanometer is also provided.
