SUMMARY
OPTIMUM DESIGN OF THREE-PHASE SQUIRREL CAGE INDUCTION MOTOR BASED ON EFFICIENCE MAXIMIZATION WITH
ARTIFICIAL NEURAL NETWORKS
Doan Due Tung, Nguyen Ngoc My, Nguyen Thai Bao, Dang Thi Tu My Three-phase squirrel cage inducdon motor is widely used in the industry and is the mam component in the transmission. Improving engine efficiency greatly benefits not only in economic terms but also minimizes greenhouse gas emissions, thus improving the environment and minimizing the risk to human health.
This article presents the result of optimum design of three-phase squirrel cage induction motor based on efficient maximization that has been analyzed and compared with other motor.
