摘要

根据消磁规律，分析了内置永磁式无刷直流电动机的反电动势谐波特性。消磁模式包括等量、不等量和加权消磁。此外，我们使用了相同的极槽比不同的极槽数模型和不同的极槽比不同的极槽数模型。此外，我们还分析了磁链、反电动势和反电动势的谐波。综上所述，我们提出了利用内置永磁式无刷直流电动机反电动势谐波特性检测不可逆退磁状态的技术。

BEMF characteristic analysis of IPM type motor according to demagnetization pattern of permanent magnet

This paper is analyzed on back electromotive force harmonic characteristic in interior permanent magnet type brushless DC motors according to demagnetization patterns. Demagnetization patterns consist of equality, inequality, and weighted demagnetization. In addition, we used the same pole-slot ratio with different pole-slot numbers models and different pole-slot ratio with different pole-slot numbers model. Furthermore, we performed analysis of flux linkage, back electromotive force, and harmonics of back electromotive force according to demagnetization patterns. In conclusion, we propose detection technique of irreversible demagnetization condition using back electromotive force harmonics characteristic of an interior permanent magnet type brushless DC motors.
