    • A C-shaped bobbin includes a bobbin base member adjacent and attached to a first lateral leg of an actuator coil. A bobbin recess, adjacent the bobbin base member, separates first and second bobbin wings. The first and second bobbin wings define first and second wing lengths measured parallel to first and second longitudinal legs of the coil, respectively, and also define first and second wing widths measured normal to the first and second longitudinal legs, respectively. The bobbin recess defines a recess depth measured normal to the first lateral leg, and defines a recess width measured parallel to the first lateral leg. Each of the first and second wing lengths is less than the length of the longitudinal legs. The recess depth is at least half a base member width. The recess width is at least twice the first wing width and/or the second wing width.
    • C形绕线架包括与致动器线圈的第一侧腿相邻并附接的绕线筒基座。 与梭芯基部件相邻的绕线筒凹槽分离第一和第二线轴架。 第一和第二梭骨架分别限定平行于线圈的第一和第二纵向腿部测量的第一和第二翼长度,并且还分别限定垂直于第一和第二纵向腿部测量的第一和第二翼部宽度。 梭心凹槽限定了垂直于第一侧腿测量的凹陷深度,并且限定了平行于第一侧腿测量的凹陷宽度。 第一和第二翼长中的每一个都小于纵向腿的长度。 凹陷深度至少为基础构件宽度的一半。 凹槽宽度至少是第一机翼宽度和/或第二机翼宽度的两倍。

    • A device for rotary driving of a round disk, for instance a memory disk of a computer, comprises a stator disposed fixedly relative to a frame and a rotor rotatably drivable relative to the stator. According to the invention the rotor comprises a concentric ring to which the peripheral edge of the disk is connected. The stator has an encircling recess, the form of which corresponds to that of the ring such that the ring fits with clearance into the recess. The rotor is provided with two collars of magnetically active elements in angularly equidistant arrangement, and the stator comprises electromagnets disposed at the same angular distances. The arrangement is such that the rotor and the stator together form an annular induction motor. The rotor is preferably suspended magnetically during operation.
    • 用于旋转驱动圆盘(例如计算机的存储盘)的装置包括相对于框架固定的定子和相对于定子可转动地驱动的转子。 根据本发明,转子包括一个同心环,圆盘的周边边缘连接着同心环。 定子具有环形凹部,其形状对应于环的凹槽,使得环与间隙配合到凹部中。 转子设置有两个角度等距离布置的磁性有源元件的两个环,定子包括以相同的角距离设置的电磁体。 该结构使得转子和定子一起形成环形感应电动机。 转子优选在操作过程中磁悬浮。
