    • The actuator (ACT) comprises: a DC motor (MOT) having an armature energized via brushes (B) and a bar commutator with segments (L) and driving the movable element (LD) by way of a mechanical transmission device (TRD), and a device (DD) for detecting and counting the commutations occurring between the brushes (B) and the bar commutator segments (L), the mechanical transmission device (TRD) comprises a transmission element (BRK) such that, during the maneuvering phases of the movable element (LD), the supply current to the motor (MOT) is always non zero and always flows in the direction defined by the “motor” operation of the motor (MOT).
    • 致动器(ACT)包括:具有电枢通电刷(B)的电动机(MOT)和具有段(L)的杆换向器,并通过机械传动装置(TRD)驱动可移动元件(LD) 以及用于检测和计数在电刷(B)和条形换向器片段(L)之间发生的换向的装置(DD),机械传动装置(TRD)包括传动元件(BRK),使得在操纵 可移动元件(LD),到电机(MOT)的供电电流始终为零,并且始终沿电动机(MOT)的“电动机”运行所限定的方向流动。
