用于个人护理器具的具有分组磁体的致动器
摘要：
一种用于个人护理器具的致动器，其包括壳体、主轴、切向致动器部分、轴向致动器部分以及控制器。切向致动器部分包括第一磁体及磁极组件，具有在第一径向定向和极性顺序中的壳体内分开的个体分组磁体段的第一序列，以及在第一径向配置中围绕主轴的磁极构件的第一磁极组件，第二磁体及磁极组件，具有在第二径向定向和极性顺序中的壳体内分开的个体分组磁体段的第二序列，以及在第二径向配置中围绕主轴的磁极构件的第二磁极组件，以及在第一磁体及磁极组件与第二磁体及磁极组件之间围绕主轴被设置的电磁线圈。响应于旋转控制信号被施加到电磁线圈，切向致动器部分相对于壳体围绕主轴线旋转地移位主轴。
摘要（英）：

Actuator for a personal care appliance comprising a housing, a spindle, a tangential actuator portion, an axial actuator portion, and a controller. The tangential actuator portion comprises a first magnet and pole assembly having a first sequence of individual grouped magnet segments spaced apart within the housing in a first radial orientation and polarity order, and a first pole assembly of pole members in a first radial configuration about the spindle, a second magnet and pole assembly having a second sequence of individual grouped magnet segments spaced apart within the housing in a second radial orientation and polarity order, and a second pole assembly of pole members in a second radial configuration about the spindle, and an electromagnetic coil disposed about the spindle in-between the first and second magnet and pole assemblies. The tangential actuator portion rotationally displaces the spindle with respect to the housing about a principal axis, in response to the rotation control signals applied to the electromagnetic coil.
