本文提出了一种轻型低成本轴向磁通永磁电机的设计和分析框架，该电机由双永磁转子和无铁心印刷电路板定子组成。去除传统的叠片定子铁芯显著降低了铁芯损耗，降低了齿槽效应和转矩涟漪，并提高了效率。所提出的设计大大消除了转子和定子之间的磁力以及转矩涟漪，从而降低了噪声。提出了一种采用高效率碳化硅MOSFET逆变器设计的全集成变频驱动器。使用印刷电路板定子可实现更简单和更快的制造。一个内部的分析模拟已被用来模拟电机的设计和评估的性能。所提出的设计已经制造并成功测试。最后，将试验结果与仿真结果以及有限元分析结果进行了比较。
This paper presents a framework for the design and analysis of a light and low-cost axial flux permanent magnet motor which consists of dual permanent magnet rotors and a coreless Printed Circuit Board stator. Removal of the conventional laminated stator core significantly reduces core losses, decreases cogging and torque ripple and increases efficiency. The proposed design drastically eliminates magnetic forces between the rotor and the stator as well as the torque ripple, hence reduces the acoustic noise. A fully integrated variable frequency drive is proposed which uses high efficiency silicon carbide MOSFET inverter design. Using Printed Circuit Board stator enables simpler and faster manufacturing. An in-house analytical simulation has been used to model the motor design and evaluate the performance. The proposed design has been manufactured and was tested successfully. Finally, the test results are compared with the simulation results as well as finite element analysis.
