Abstract:
A magnet arrangement for interacting with drive coils of an electric motor comprises a first drive magnet, a second drive magnet, and a compensation magnet arranged between a coil-facing side of the magnet arrangement and a coil-averted side of the magnet arrangement. The compensation magnet is arranged between the first drive magnet and the second drive magnet. The first drive magnet has a first cross-sectional area, the second drive magnet has a second cross-sectional area, and the compensation magnet has a third cross-sectional area; e.g., with a coil-facing width of the first cross-sectional area and a coil-facing width of the second cross-sectional area in each case greater than a coil-facing width of the third cross-sectional area, a coil-averted width of the third cross-sectional area greater than the coil-facing width of the third cross-sectional area, and the third cross-sectional area undercuts the first and second cross-sectional area on the coil-averted side.
