低损耗、高效率的发展是一个必要的要求。通过引入E&S模型的矢量磁特性分析，可以从磁功率损耗分析中得到降低损耗以提高效率的方法。采用矢量磁特性技术实现了低损耗、高效率的升级。减小了升压齿轮产生的机械损耗，提高了发电效率。因此，机械损耗可降低80%以上。防止了磁芯材料磁性特性的恶化。为降低制造过程中产生的残余应力，设计了诱导退火方法。采用矢量磁特性控制技术对磁芯、线圈和永磁体结构进行了调整。研制了矢量磁特性控制材料。

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.
