添加制造的导体的电导率(EC)可以通过改变内置取向和后处理条件来有目的地控制。在采用实心导体的电机中，可利用此功能将绕组交流电流(AC)损耗降至最低。本文研究了基于附加制造的航空用高比功率永磁电机的绕组设计。具体地说，槽口附近的导线设计为低EC以减少绕组交流损耗，而槽底附近的导线采用较高的EC以降低直流损耗。以高比功率和高效率为目标，建立了参数有限元模型，进行了全面的设计参数分析。对提出的线圈概念在非均匀EC下的实现进行了讨论和论证。
Electrical conductivity (EC) of additively manufactured conductors can be purposely controlled by changing asbuilt orientation and postprocessing conditions. This feature can be leveraged to minimize winding alternate current (AC) losses in electrical machines adopting solid conductors. This paper deals with additive-manufacturing-based winding design of a high-specific-power permanent-magnet (PM) machine for aerospace applications. Specifically, conductors near slot opening are designed with low EC to reduce winding AC losses while conductors near slot bottom adopt higher EC to reduce direct current (DC) losses. Parametric finite element (FE) models are developed for a thorough design parametric analysis targeting high-specific-power as well as high efficiency. The implementation of the proposed coil concept with inhomogeneous EC are discussed and demonstrated.
