Abstract

After more than 100 years of development, rotating electric machines are a mature industrial product. Nevertheless improvements are still possible for specific applications, and it is likely that the major evolution will be promoted by unconventional structures. Among them, some of the most interesting proposals have a three dimensional flux path. Due to the magnetic circuit geometry, the unconventional "3D motors" suffer the difficulties in adopting the laminated iron technology: the problem can be afforded adopting new materials, such as plastic or powder magnetic composite material. Hence, unconventional motor structures and new materials open a possible evolution in the electric machines and drives scenario. Today, plastic materials are an infrequent choice for the electric machines structural parts, but, pioneering applications, such as aeronautical components, let some technological scouting: a low weight-high efficiency plastic axial flux motor for a solar flying platform is presented as example of a combined new material-new geometry development.

“塑料”电机:轴向磁通机的可行解决方案

旋转电机经过100多年的发展，是一种成熟的工业产品。尽管如此，对于特定的应用仍有改进的可能，非常规结构很可能会推动主要的发展。其中，一些最有趣的建议具有三维通量路径。由于磁路的几何形状，非常规的“3D电机”在采用层压铁技术时遇到了困难:采用塑料或粉末磁性复合材料等新材料可以解决这个问题。因此，非常规的电机结构和新材料为电机和驱动器的发展开辟了一条可能的道路。今天，塑料材料是电机结构部件的罕见选择，但是，开创性的应用，如航空部件，让一些技术探索:用于太阳能飞行平台的低重量-高效率塑料轴向磁通电机是新材料-新几何结构结合发展的例子。
