Analysis on increasing energy efficiency in regional railways by the introduction of permanent magnet synchronous motors

Enhancing efficiency has become a fundamental requirement across contemporary technological endeavors aimed at energy conversion. The imperative lies in achieving global energy resource preservation objectives. Novel methods of energy utilization with heightened efficiency are progressively gaining traction, accompanied by the intricacies of refining existing technologies. This research undertakes an examination of the amplified energy efficiency within regional rail systems, achieved through the adoption of permanent magnet synchronous motors (PMSMs) as primary electric propulsion systems, particularly when juxtaposed with induction motors. Delving into the theoretical engineering attributes of PMSMs, coupled with the establishment of dynamic motion characteristics and comprehensive simulations, offers a pathway to amassing empirical insights pertaining to efficiency studies.
