电动机磁性组合
摘要：
用于与电动机的驱动线圈相互作用的磁体装置(100)包括第一驱动磁体(110)，第二驱动磁体(120)，以及补偿磁体(130)，其配置于面向线圈的该磁体装置(100)的一侧(103)及面脱机圈的磁体装置(100)的一侧(104)。补偿磁体(130)配置于第一驱动磁体(110)与第二驱动磁体(120)之间。第一驱动磁体(110)具有第一截面区域(112)，第二驱动磁体(120)具有第二截面区域(122)，且补偿磁体(130)具有第三截面区域(132)。面向线圈的第一截面区域(112)的宽度(113)与面向线圈的第二截面区域(122)的宽度(123)分别大于面向线圈的第三截面区域(132)的宽度(133)。面脱机圈的第三截面区域(132)的宽度(134)是大于面向线圈的第三截面区域(132)的宽度(133)，且第三截面区域(132)底切面脱机圈的一侧(104)上的第一与第二截面区域(112，122)。
摘要（英）：

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.
