Abstract: An EMC test system for a rotating load includes a shielded chamber, a rotating load, a first connecting shaft, a compressor, a fluid pipeline, a fluid motor, a second connecting shaft and a motor load. The rotating load, the first connecting shaft and the compressor are arranged inside the shielded chamber. The fluid motor, the second connecting shaft and the motor load are arranged outside the shielded chamber. The rotating load is connected to the compressor through the first connecting shaft. The compressor is connected to the fluid motor through the fluid pipeline. The fluid motor is connected to the motor load through the second connecting shaft. The fluid pipeline passes through the shielded chamber. The compressor is employed such that energy is transferred to the outdoors through the transmission of fluid, and then converted into electric energy.

Abstract: A laminated busbar assembly includes a substrate, a positive current metal plate provided with a first pin, a negative current metal plate provided with a second pin, and an output current metal plate provided with a third pin. The substrate is provided with a pad hole group including a first pad hole, a second pad hole, and a third pad hole. The pad hole group is electrically connected to copper cladded on the substrate to form wirings. The positive current metal plate, the negative current metal plate, and the output current metal plate re all arranged on the first side of the substrate in a laminated manner. The first pin passes through first pad hole, the second pin passes through the second pad hole, and the third pin passes through the third pad hole.

Abstract: An AC motor controller, a laminated busbar assembly, and a manufacturing method thereof relate to the field of electrical devices. The AC motor controller includes laminated busbar assembly, controllable switching element assembly, and filter element assembly. The laminated busbar assembly includes a substrate, a positive current metal plate, a negative current metal plate, and an output current metal plate which are arranged in a laminated manner. In the insertion and tin soldering process, the processing of the AC motor controller is completed by two steps: passing the first pin of the positive current metal plate, the second pin of the negative current metal plate, the third pin of the output current metal plate, the controllable switching element assembly, and the filter element assembly through the pad hole group of the substrate, and then performing soldering in one-off manner, so the production is efficient.
