摘要

本文的目的是研究无磁分段电枢轴向磁通永磁(YASA-AFPM)发电机的热行为和负载特性,该发电机使用了一种改进的三维耦合电磁热方法。首先,使用所提出的方法对1kW YASA-AFPM发电机进行了建模和分析;确定了发电机不同部件的瞬态温度和稳态温度。为了提高建模精度,在协同模拟的每个步骤,在热模型和电磁模型之间交换信息,同时考虑损失的精确计算和温升对材料温度相关特性的影响。然后,利用所提出的方法,研究了槽开口宽度和定子节段匝数对发电机负载能力的影响。然后进行了实验测试。结果表明,该方法预测机器负载能力和热性能的有效性和准确性。

Investigation into the Thermal Behavior and Loadability Characteristic of a YASA-AFPM Generator via an Improved 3-D Coupled Electromagnetic-Thermal Approach
The objective of this paper is to investigate the thermal behaviour and loadability characteristic of a yokeless and segmented armature axial-flux permanent-magnet (YASA-AFPM) generator, which uses an improved 3-D coupled electromagnetic-thermal approach. Firstly, a 1-kW YASA-AFPM generator is modelled and analysed by using the proposed approach; the transient and steady-state temperatures of different parts of the generator are determined. To improve the modelling accuracy, the information is exchanged between the thermal and electromagnetic models at each step of the co-simulation, considering both the accurate calculation of losses and the impacts of temperature rise on the temperature-dependent characteristics of the materials. Then, by using the proposed approach, the impact of the slot opening width and the turn number of stator segments on the generator loadability are investigated. After that, the experimental tests are performed. The results reveal the effectiveness and accuracy of the approach to predict the machine loadability and thermal behavior.
