This paper describes a comparison of the performance characteristics of a 2.2 kW induction motor with conventional Die-cast Aluminium Rotor (DAR) to that of a 2.2 kW induction motor with proposed Die-cast Copper Rotor (DCR). Both the motors are fabricated and its steady state characteristics are compared using MATLAB 7 software whose inputs are No-load and Blocked rotor tests obtained from the above motors. The actual load tests were also performed in the motors in accordance with IS 12615: 2004 standard.
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.
