Abstract


The compulsator system based on magnetic suspension flywheel conbines all thefunctions of inertia energy storage, voltage generation and pulse power shaping in onemachine. As a high power supply, these advantages makes it very suitable forelectromagnetic lounching, laser veapon, direction energy weapon and so on.Based on the introduction of the background of the study of the magneticsuspension energy storage flywheel and the compensated pulsed alternator(CPA), thispaper analysised the development of the magnetic suspension energy storage flywheeland the CPA, and looked into the future of the Compulsator system based on magneticsuspension flywheel. And elaborated the important of the study.In this paper, the mechanism of the magnetic suspension energy storage flywheeland the CPA flywheel were studied with both the analytical and numerical method, thedistribution of the magnetic flux and the dynamic features of the AMB and the CPAwas obtained, and the armature inductance solution in the CPA was derived. Accordingto the analysis of mutual affects between magnetic suspension energy storage flywheeland CPA system, the impact of the pulse was discussed and a controllor for activemagnetic bearing(AMB) is designed. Based on the analysis above, it proved thefeasibility of the magnetical suspended and energy storage CPA system. Then with boththe analytical and numerical method, the electromagnetic characteristic, the pulse loadcharacteristic and the pulse wave adjusting method of the system were studied，and thekey technologies are attained. A 4.5MJ-50MW prototype system was designed.According to the study above, it makes a definite feasibility to manufacture amagnetical suspended and energy storage CPA system based on the technology for highpower pulse alternator based on flywheel energy storage system. All the work aboveprovide the foundation for next manufacture and deburg step for the prototype and studyfor the CPA-based weapon system.
