Optimizing machine learning models for granular NdFeB

We conducted several tests of a variety of supervised machine learning (ML) models including kernel ridge regression (KRR), support vector regression (SVR), and artificial neural network (ANN) regression. The hyper-parameters of these models were optimized by a very fast simulated annealing (VFSA) algorithm with an adaptive cooling 4.2.

Inherent Difference in Saliency for Generators with Different

The inherent differences between salient and nonsalient electrical machines are evaluated for two permanent magnet generators with different configurations. The neodymium based (NdFeB) permanent magnets (PMs) in a generator are substituted with ferrite magnets and the characteristics of the NdFeB generator and the ferrite When the NdFeB is in both d and q axes, the L q of the machine can be further decreased, and higher positive d-axis current can be applied under load condition. The variation range of MS VR of topology III is wider owing to the bypass flux path, which is adjustable by changing the distance of two NdFeB magnets D N near the AlNiCo. 100% Comparative study of hybrid-PM variable-flux machines with
