摘　　要：“电机学”课程中涉及的磁场、温度场等物理场的原理分析与“电路理论”课程中的定理存在异曲同工之处。本文通过分析一阶电路全响应、欧姆定律和基尔霍夫定律、叠加定理,总结出物理场建模的一般规律和共性特征,并基于此分析了电机的温度场建模、磁路的欧姆定律和基尔霍夫定律以及dq轴电枢反应,验证了电路与电机物理场共性特征的正确性。文章对电路定理与电机物理场建模过程进行类比,归纳了电路定理与电机建模中存在的共性问题,并将其融入电机学教学方法中。该方法的应用有助于提高学生对电机模型构建本质的理解,增强学生对电气工程专业各类型课程之间触类旁通、举一反三的思维能力。The principles of physical fields such as magnetic field and temperature field in“Electrical Engineering”are similar to the theorems in“Circuit Theory”.Hence,this paper aims to summarize the general laws and common features of physical field modeling by expounding the full response of the first-order circuit,Ohm’s law,Kirchhoff’s law and superposition theorem,and on this basis analyzes the temperature field modeling of the motor,Ohm’s law and Kirchhoff’s law of magnetic circuit,and dq-axis armature response to verify the common features of physical fields of electric circuits and motors.The analogy between circuit theorem and the process of motor modeling is also made to summarize their common problems The application of this method is conducive to improve students’understanding of the nature of motor modeling and enhance their ability to relate to various courses of electrical engineering.
