摘要
直流电机的感应电动势是电机学中重要的教学内容之一,这部分内容涉及绕组的连接规律和磁场的分布规律.采用严密的数学推导和逻辑推理,介绍了直流电机感应电动势的推导过程.将这种推导过程应用于教学中,使学生知其然,知其所以然,取得了较好的教学效果.
The induced electromotive force of DC motor is one of the important teaching content of motor, this part relates to the connection rule of winding and the distribution of magnetic field, the mathematical derivation and rigorous logical reasoning, introduces the derivation of induced electromotive force of DC motor, the derivation process is applied to the teaching, make the students know the of course, also know why, has obtained the good teaching effect.
