永磁同步电机是一种高效的运动解决方案。随着效率条的提高，仅考虑主导磁芯、直流传导和摩擦损耗已不再足够。对于经历额外损耗的电机开发人员来说，挑战在于确定先前被忽视的损耗中哪些对他们的电机来说是重要的。这项研究提出了一种最佳拟合的最小二乘法损失分离，可以应用到实验数据，以突出额外的损失的来源。这是一个强大的工具，为实际的电机设计师寻求满足具有挑战性的规格。所提出的技术已被应用到三个不同的原型电机的实验数据。虽然使用了一个简单的核心模型的核心损失，在每种情况下的损失进行了分类，残差小于2%。每种损耗类型（由速度和电流的比例定义）与FEA计算的相应损耗类型吻合良好。
Permanent magnet synchronous machines are a high efficiency motion solution. As the efficiency bar is raised, it is no longer adequate to consider only the dominant core, DC conduction and friction losses. The challenge for motor developers experiencing additional losses is determining which of the previously neglected losses is significant for their motor. This research presents a best-fit least-squares approach to loss separation that can be applied to experimental data to highlight the source of additional losses. This is a powerful tool for practical motor designers looking to meet challenging specifications. The proposed technique has been applied to the experimental data from three different prototype motors. Although a simple core model of core loss is used, in each case the losses were classified with a residual of less than 2%. Each loss type (defined by proportionality to speed and current) showed good agreement with the corresponding loss type calculated from FEA.
