IEC 62520:2011适用于推进铁路和公路车辆的短初级直线感应电动机（LIM）。本标准适用于LIM的特定配置，其主要安装在车身或卡车上，次要安装在轨道上，仅通过磁场与主要连接。本标准的目的是通过试验确认LIM的性能，并为评估其适用于特定任务提供依据。

IEC 62520:2011 applies to short-primary type linear induction motors (LIM) for propelling rail and road vehicles. This standard applies to a specific configuration of LIM that has the primary mounted on either the vehicle body or trucks and a secondary that is fixed to the track and that is connected only by a magnetic field with the primary. The object of this standard is to allow the performance of a LIM to be confirmed by tests and to provide a basis for assessment of its suitability for a specified duty.
