E.力矩马达力矩马达是最常用的电磁致动器。图11表示其典型结构。定铁和衔铁由铁磁材料制成。衔铁绕销轴转动,但其转动受到一个强弹簧的限制。往往销轴本身就是起扭簧作用的力矩杆。虽也有其他结构,但本文将讨论这种结构。衔铁运动通常在±0.5×10~(-4)到 E. Torque motor Torque motor is the most commonly used electromagnetic actuator. Figure 11 shows its typical structure. Fixed iron and armature made of ferromagnetic material. The armature rotates about the pin, but its rotation is limited by a strong spring. Often the pin shaft itself acts as a torsion spring torque rod. Although there are other structures, this article will discuss this structure. Armature movement is usually ± 0.5 × 10 ~ (-4) to
