The blasting fuse power source design is in a modern blasting fuse design main content, this topic through magnetic-electric revolves the electricity generation design technology research to the blasting fuse, first introduced the blasting fuse power source and the blasting fuse environment concept, the generator type and the development course, and emphatically introduced magnetic-electric the blasting fuse generator characteristic, first theoretically had a more profound understanding to the blasting magnetic-electric fuse generator. Then through the actual design small generator, has carried on the structure analysis to the design small generator, specially has carried on the introduction to the generator core part permanent-magnet material, again carries on the mathematical model analysis, finally tests the generator through the experiment the performance, and to tested has made the related data analysis.
