Research Abstract

A necessary requirement is as follows for the development of a low-loss and highly efficiency.1.The decrease of loss for high efficiency can be obtained from the magnetic power loss analysis by the vector magnetic characteristic analysis that introduces the E&S model.2.The vector magnetic characteristic technology is applied for the low loss and upgrading to highly efficiency.3.The decrease of mechanical ossoccurred in the step-up gear is decreased, and the power generation efficiency is improved. As a result, the mechanical loss can be decreased by 80% or more.4.Deterioration in the magnetic characteristic of the core material is prvented. The induced annealing method was designed for the decrease of the residual stress generated in manufacturing.5.The adjustment of the core, the coil, and the permanent-magnet structure is attempted by the vector magnetic characteristic control technology.The vector magnetic characteristic control material was developed.
