要約(英語): In most manufacturing cases of a permanent magnet synchronous motor (PMSM), the permanent magnet (PM) is magnetized post-assembly. A magnetization process with high accuracy is desirable for manufacturing a high-performance PMSM, and therefore, estimating the magnetization of the PM is essential. Estimation methods for PM magnetization have been proposed however, to the best of the author's knowledge, no method has been applied to the magnetic circuit with a nonlinear iron core. In this paper, the Magnetization Estimation using the Leakage Flux derived from the magnetic circuit (MELF) is proposed. The fundamental performance of MELF is verified using the rotor of the IEEJ N-model, which is the benchmark PMSM.
