伺服电机（servo motor ）是指在伺服系统中控制机械元件运转的发动机，是一种补助马达间接变速装置。伺服电机可使控制速度，位置精度非常准确，可以将电压信号转化为转矩和转速以驱动控制对象。伺服电机转子转速受输入信号控制，并能快速反应，在自动控制系统中，用作执行元件，且具有机电时间常数小、线性度高、始动电压等特性，可把所收到的电信号转换成电动机轴上的角位移或角速度输出。分为直流和交流伺服电动机两大类，其主要特点是，当信号电压为零时无自转现象，转速随着转矩的增加而匀速下降。

  减速器及伺服电机进口通关报关流程及注意事项

  1：进口商在进口前需要确定企业自身报关资质，是否有进口资质。国外货源及国际贸易条款等细节问题，一般贸易条款如CIF（国外送货到国内指定港口），FOB（进口商在国外指定港口提货），EXW（国内进口商负责从国外工厂提货，海运等门到门）。对于首次和国外供应商合作建议用信用证的方式办理付汇，以减少国内进口商国际贸易风险。 

  减速机/伺服电机进口报关流程

  1: Importers need to determine their own import before the declaration of their own qualifications, whether import qualification. Foreign goods and international trade terms and other details, general trade terms such as CIF (foreign domestic delivery to the designated port), FOB (named port of delivery in foreign importers), EXW (domestic importers responsible for delivery, shipping and other foreign factories from door to door). For the first time and foreign suppliers to cooperate with the letter of credit for the payment of foreign exchange in order to reduce the risk of international trade.

  2：减速器、伺服电机进口是受3C监管的，进口商在进口前需要和国外供应商确定是否能提供相关3C认证，如果提供不了，需要把该产品的电压、线路图纸、HS编码等提供我司确定进口方案。

  2: speed reducer, servo motor is imported by the 3C monitoring, importers in the import and foreign suppliers to determine whether can provide 3C certification, if not provided, need to put the product of voltage and line drawings and HS encoding to provide our determined import scheme.

  3：货物到国内港口后我司办理港口清关报关事宜，海关商检放行后，我司安排送货到进口商指定仓库，欢迎来电咨询，

  3: after the goods to the port of our country for the port customs clearance, customs inspection release, I arrange delivery to the importer designated warehouse, welcome to inquire,
