Abstract:For permanent magnet linear motors (PMLMs), large temperature rise can damage their performance and limit their output. Water-cooling system can be designed to reduce temperature rise and to improve thrust density. In order to study the thermal performance of a water-cooled, 14-pole, 12-slot PMLM, the finite element model and the thermal network model are erected. For water-cooled type PMLM, the modeling difficulties are solved. Under continuous duty, the temperature distribution of this PMLM is investigated b… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
