Linear Motor Topology Study and Prospect of Abandoned Mine-Type/Mountain Gravity Energy Storage

With the escalating demand for renewable energy, the evolution of energy storage technology emerges as a vital trajectory. Specifically, mine-type/mountain gravity energy storage systems, which, due to their large scale, efficient reuse of waste resources, and significant energy storage capacity, present substantial development potential. This study begins by comparing and analyzing both prevailing and newly proposed gravity energy storage technologies. Moreover, the types of linear motor structures adapted to the newly proposed gravity energy storage system are also analyzed. Subsequent comprehensive analysis of current linear motor characteristics seeks to identify the most suitable topology, aligned with motor performance criteria for a specific gravity energy storage system. Finally, a forward-looking perspective on pivotal technologies within mine- type/mountain gravity energy storage systems emerges.
