提出了一种定速飞轮储能系统，并通过样机验证了通过减小转动惯量来释放能量。在这项研究中，能量平衡之间的机械功（输入），以改变惯性和电输出进行了理论和实验分析。结果，实验中测量的放电能量变得低于理论值，特别是当放电能量大时。误差必须来自电动机/发电机、齿轮头、轴承摩擦等的损耗。
A fixed-speed flywheel energy storage system has been proposed, and energy discharge by reducing moment of inertia has been demonstrated by a prototype. In this study, energy balance between mechanical work (input) for changing the inertia and electrical output has been analyzed theoretically and experimentally. As a result, the discharged energy measured in the experiment became lower than the theoretical value, especially when the discharged energy was large. The errors must be derived from losses in the motor/generator, the gear head, the bearing friction, and so on.
