Problems solved by technology

At present, in the field of electromagnetic compatibility testing, the electromagnetic compatibility test for the two working modes of the motor is carried out separately, that is, only the load test or drive test can be performed on the tested motor separately. When the two working modes of the motor need to be tested at the same time, The experimenter needs to replace the test system after a test is completed, which increases the workload of the experimenter and reduces the efficiency of the experiment

Abstract

The invention provides a motor loading and driving system for electromagnetic compatibility testing, including a testing device, a first transmission device, a motor under test, a driving power supply, a first photoelectric conversion module, a second photoelectric conversion module and a control device, wherein The test device includes a loading module, a driving module, a clutch, a second transmission device, and a third transmission device; the system provided by the present invention does not introduce additional electromagnetic disturbances, meets the requirements of the electromagnetic compatibility test standard for auxiliary equipment, and can be placed in radio waves It is used in a dark room, and at the same time, the system provided by the present invention can not only carry out loading test on the tested motor, but also carry out driving test on the tested motor, and the two test methods can be switched with one key, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the field of electromagnetic compatibility testing, in particular to a motor loading and driving system for electromagnetic compatibility testing. Background technique [0002] Carrying out electromagnetic compatibility (EMC) tests for new energy vehicles is the basic guarantee to ensure the safe and reliable operation of vehicles, and it is also the key to new energy vehicle product research and development, testing and certification, and industrialization development. Computer management and electronic control systems widely used in automobiles must comply with the measurement requirements of automotive electronic electromagnetic compatibility, including interference testing (EMI) and immunity testing (EMS). At present, my country has relevant EMC detection and test technical method standards for traditional automobiles, and the corresponding detection and test capabilities are gradually improving. However, for new energy veh...
