弹簧复位节气门致动器、其控制方法和节气门组件
摘要：
一种弹簧复位节气门致动器(1)，包括：具有输出轴(4)的电动多线圈(C1、C2、C3)DC马达(2)、节气门复位弹簧(10)、连接到所述输出轴的齿轮传动装置(5)、控制单元(CPU)，其配置为控制向所述DC马达(2)的电力供应，其中，弹簧复位节气门致动器(1)具有在节气门关闭和节气门完全打开之间的运动范围。控制单元(CPU)被布置为使至少两个DC马达线圈(C1、C2、C3)短路以产生DC马达复位抵抗扭矩，并且控制单元(CPU)包括运动监控线路，其被布置为监控由节气门复位弹簧(10)强制并由DC马达复位抵抗扭矩抵抗的致动器运动。本发明还涉及一种方法和节气门组件。
摘要（英）：

A spring return throttle actuator (1) including: an electric, plural-coil (C1, C2, C3), DC motor (2) having an output shaft 4, a throttle return spring (10), a gear transmission (5) connected to the output shaft, a control unit (CPU) adapted to control power supply to the DC motor (2), wherein the spring return throttle actuator (1) has a movement range between closed throttle and opened throttle. The control unit (CPU) is arranged to short-circuit at least two DC motor coils (C1, C2, C3) in order to create a DC motor return resist torque, and the control unit (CPU) includes a movement monitoring circuit being arranged to monitor actuator movement forced by the throttle return spring (10) and resisted by the DC motor return resist torque. The invention also relates to a method and a throttle assembly.
