• ### Estimation of the Core Losses of Induction Machines Based on the Corrected Epstein Test Method

Publication Year: 2019, Article Sequence Number: 6300208
| | PDF (2000 KB) | HTML

A revised method based on the standard Epstein test is proposed to improve the accuracy of the estimation of the core losses of induction machines (IMs). Since the magnetic field strength patterns at the four corners of the standard test samples are non-uniform, high-order excess losses at the corners would deteriorate the accuracy of the model for core losses. To address this issue, test samples ... View full abstract»
