Inserting ferrofluids in the gap between the acting magnets of electrical machines will enlarge the forces or torques by reducing the magnetic resistance of the gap. Based on this effect, the efficiency of linear and rotating electric drives can be improved. The experimental setup to measure this force amplification in the case of a linear electric drive and the results are presented.
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.
