基于解析法的交流电机电枢绕组磁动势研究

Research on Magnetic Momentum of AC Motor Armature Winding Based on Analytical Method

  • 摘要: 交流电机电枢绕组的磁动势是电机学教学的重要内容。交流电机电枢绕组的磁动势既与时间有关,又与空间有关,比较抽象,导致学生不容易理解。该文基于解析法对交流电机电枢绕组的磁动势进行分析,并对交流电机定子绕组星形接法绕组缺相、定子绕组三角形接法电源供电及绕组断线缺相、交流电机能耗制动等几种特殊情况产生的磁动势进行分析。该方法有助于促进学生更好地理解交流电机的磁动势,并且能够提高学生分析问题、解决问题的能力。实践表明,该教学研究能够获得良好的教学效果。

     

    Abstract: Armature winding magnetic motive force of AC machine is an essential part of Electric Machinery. The magnetic motive force of the armature winding of an AC motor is related to time and space. This concept is more abstract, which makes it difficult for students to understand. This paper analyzes the magnetic motive force of AC motor armature produced by some special conditions, such as star connection of AC motor stator winding lack-phase, power supply and winding disconnection of delta connection stator winding and AC motor dynamic braking. This method helps to promote students to better understand the magnetic motive force of AC motors, and can improve students’ ability to analyze and solve problems. Practice shows that the teaching research can obtain good teaching effects.
