电机学课程中的磁路及相关内容

MAGNETIC CIRCUITS AND THEIR RELATIVES IN ELECTRIC MACHINERY COURSE

本文从电机学要求出发 ,介绍磁路及相关内容 ,它主要包括铁磁物质、磁路定律、电磁感应定律和电感的电抗等问题。本文着重介绍在电路与电机学教科书中介绍甚少或没有提及而又是电机学十分需要的、以及结合电机与变压器特点的这方面的内容。此外 ,本文还对磁路及相关内容中的一些问题给予严格的定义或说明。

The paper introduces the magnetic circuits and their relatives in electric Machinery Course,including the ferromagnetics, law of magnetic circuit, law of electromagnetic induction and the inductance reactance, from the need for the course teaching.The topics which have seldom or not been presented in 〈Electric Circuits〉 or 〈Electric Machinery〉 textbooks, and are necessary for the Electric Machinery teaching, and are closely in tegrated with the properties of electric machines and transformers are stressed. And, some strict definitions of explanations for the analyses of magnetic circuits are give.
