The invention relates to a device which used for detecting linear motor performance on rail traffic. The orbit (8) was installed on the shelves ,the sublevel (11) was installed on the orbit, the primary winding of the linear motor (6) and (7) and convertors(3)and (2) were installed on the bogies. The two primary winding were connected by rigidity axes (9).The AC terminal of the first convertor was joined with the primary of the first linear motor. The DC terminal of the first convertor was joined with the four quadrant convertor (1). The AC terminal of the second convertor (3) was joined with the primary (6) of the second linear motor. The DC terminal of the first convertor was joined with the four quadrant convertor. The DC part of the traction and laden convertor were joined together and the AC terminal of the four quadrant convertor was joined with power supply. This invention solved the problem that the rotation test can not detect linear motor on rail traffic reliably.
Description
technical field [0001] The invention relates to a device for detecting the performance of a linear motor. Background technique [0002] The linear motor (LIM) rail transit system is a solution between the traditional wheel-rail system and the magnetic levitation system, and it has been practically applied in 9 cities in the world. For the linear motor rail transit system, the research on the linear motor comprehensive test and detection system is an important part of the research on the urban linear motor rail transit system, which plays a huge role in supporting and promoting the development of the linear motor rail transit. It is known from experience that in order to develop a new type of rail transit, it is necessary to establish a corresponding test and detection system. Through test and detection, problems can be found, verified, and solved, and provide a scientific basis for the final determination of the prototype system. [0003] The technology of linear motor trac...
