Electric motors can be damaged or operate improperly from a possible set of failures. Such failures are related to high or very low voltage and current levels, phase loss or blocked rotor. Therefore, it is important to protect these equipments through appropriate mechanisms. Alternatively, a workbench can simulate detectable failures related to the engines, allowing to change parameters, in which maintenance operators are able to identify the results of these changes. This work presents the development of a workbench as a tool for testing electrical machines and drives. The workbench is based on the Arduino programming platform (microcontroller system), in which it checks the functioning of electric motors under the condition of failures that may occur in this engine. Motor protections are carried out through an Intelligent Electronic Device (IED), which are popularly known as intelligent relays. The results show the development of a workbench that can test and identify several faults in a small three-phase motor.

智能电子设备和微控制系统的三相电动机故障测试与仿真工作台

电动机可能因一系列故障而损坏或无法正常运行。此类故障与电压和电流水平过高或过低，缺相或转子堵转有关。因此，通过适当的机制保护这些设备很重要。或者，工作台可以模拟与发动机相关的可检测故障，从而允许更改参数，维护操作员可以在其中识别这些更改的结果。这项工作介绍了工作台作为用于测试电机和驱动器的工具的发展。工作台基于Arduino编程平台（微控制器系统），在该平台上，它会在此引擎可能发生故障的情况下检查电动机的功能。电机保护通过智能电子设备（IED）进行，通常被称为智能继电器。结果显示了可以测试和识别小型三相电动机中若干故障的工作台的开发。
