IEC 61377:2016适用于由牵引电机、转换器、牵引控制设备（包括软件）、变压器、输入滤波器、制动电阻器、主断路器、冷却设备、传感器、接触器等组成的牵引系统。本标准中适用的电机类型为异步或同步，包括永磁（PMM）或直流（DC）。本标准的目的是规定牵引系统的型式试验，主要包括: -性能特性测试； -验证这些性能特征的测试方法。与以前的版本相比，这个新版本包括以下主要技术变化:它包括必要的更新，以满足当前的技术水平，提高清晰度，并创建一个考虑所有类型的电机作为牵引系统的一部分的版本。

IEC 61377:2016 applies to the traction system consisting of traction motor(s), converter(s), traction control equipment including software, transformer, input filters, brake resistors, main circuit-breaker, cooling equipment, transducers, contactors, etc. Types of motors applicable in this standard are asynchronous, or synchronous including permanent magnet (PMM), or direct current (DC). The objective of this standard is to specify the type test of a traction system, mainly comprising of:
- test of performance characteristics;
- test methods of verifying these performance characteristics. This new edition includes the following main technical changes with regard to the previous editions: it includes updates as necessary in order to meet the current technical state of the art, to improve clarity and to create an edition that considers all types of motors part of a traction system.
