EMC TEST SYSTEM APPLICABLE TO ROTATING LOAD, AND TEST METHOD THEREOF

摘要

An electromagnetic compatibility (EMC) test system applicable to a rotating load, and a test method thereof, relating to the field of EMC tests. The EMC test system comprises a shielding chamber (10), a rotating load (11), a first connecting shaft (12), a compressor (13), a fluid pipeline, a fluid motor (15), a second connecting shaft (16), and a motor load (17). The rotating load (11), the first connecting shaft (12), and the compressor (13) are disposed in the shielding chamber (10). The fluid motor (15), the second connecting shaft (16), and the motor load (17) are disposed outside the shielding chamber (10). The rotating load (11) is connected to the compressor (13) by means of the first connecting shaft (12). The compressor (13) is connected to the fluid motor (15) by means of the fluid pipe. The fluid motor (15) is connected to the motor load (17) by means of the second connecting shaft (16). The fluid pipe passes through the shielding chamber (10). Energy is transmitted to the outside by the compressor (13) using the fluid, and then converted into electric energy, thereby avoiding the problem of EMC interference generated by an electromagnetic load, and also avoiding the problem of high costs of a non-metal connecting shaft in a mechanical transmission process; thus, the test system has both high test accuracy and low costs.
