Core Loss Estimation in Electric Machines With Flux-Controlled Core Loss Tester
IEEE Transactions on Industry Applications, 2016The complexity of core loss estimation is an essential limitation for electric machine design engineers. It is critical to estimate the core losses and reduce them in the design stage to improve the machine efficiency. Current estimation methods based on the Steinmetz equation and loss separation are not accurate enough even at the rated conditions ...
