传动器设备和磁带驱动器系统
摘要：
传动器设备包括极片和用于产生磁场的至少一个磁铁。具有环绕极片的线圈的粗略定位器在平行于极片的轴的方向提供粗略传动。具有环绕极片的线圈的精细定位器在通常平行于极片的轴的方向提供精细传动。
摘要（英）：

An actuator device includes a pole piece and at least one magnet for generating a magnetic field. A coarse positioner having a coil surrounding the pole piece provides coarse actuation in a direction parallel to an axis of the pole piece. A fine positioner having a coil surrounding the pole piece provides fine actuation in a direction generally parallel to an axis of the pole piece.
