Electromagnetic compatibility refers to the equipment work properly in an electromagnetic environment adaptability . It is an emerging cross- disciplinary and highly complex , involving electromagnetic theory , electronic technology, electromagnetic measurements , signal analysis, mechanical structure , automatic control , materials and processes and other disciplines . Linear Metro Vehicle centralized layout system equipment installed in the vehicle , in which the traction inverter , the auxiliary inverter with variable frequency control, while train widespread use of high-pressure circuit high voltage, high-current high-voltage electrical equipment and electronic control equipment , which produces strong electromagnetic fields , the electrical system of the vehicle and the space environment will cause a great impact. Linear motor special mechanical structure determines the electromagnetic field distribution with the launch of its different from ordinary motors. How to make a large number of intelligent vehicle control components , miniaturized sensors, and network monitoring systems in harsh electromagnetic environment to work properly, the vehicle of the space environment electromagnetic fields, noise, etc. in line with national standards, the design of the vehicle is an important issue to be solved . Based on the Guangzhou Metro Line project linear motor vehicle electromagnetic compatibility requirements, and vehicle electromagnetic compatibility test results , combined with the system configuration and placement of equipment , detailed analysis of the linear motor vehicle sources of interference and disturbed object ; proposed linear motor vehicle specific control electromagnetic compatibility solutions and improvements , and conducted experimental verification. Test results show that the vehicle fully meet the electromagnetic compatibility requirements , the train is running well .
