可提供质保单moog伺服阀D634-319C

对伺服放大器的要求：

可提供质保单moog伺服阀D634-319C由于伺服阀马达线圈匝数较多，具有很大的感抗，所以伺服放大器必须是具有深度电流负反馈的放大器。只有极少响应较慢的系统才用电压反馈的放大器。电流负反馈放大器输出阻抗比较大，放大器和伺服阀线圈组成了一个一阶滞后环节，输出阻抗大，那么这个一阶环节的频率高，对伺服阀的频带就不会有太大的影响。放大器的功率级输出的一般原理图见图。不同的伺服系统对伺服放大器有各种不同的要求，例如不同的校正环节，不同的增益范围及其他功能。但为了确保伺服阀的正常使用，阀对放大器还提出：放大器要带有限流功能，确保放大器zui大输出电流不至于烧坏线圈或不至引起阀的其他失败。伺服阀应能耐受 2 倍额定电流的负荷。再要有一个输出调零电位器，因为伺服阀一般容许 2%的零偏，及工况不同的零漂，在伺服阀寿命期内零偏允差可到 5%～6%，所以调零机构要可调10± %的额定电流输出值，某些伺服阀和系统还要求放大器带有颤振信号发生电路。
