摘　　要：利用电磁转矩的物理表达式T_(em)=C_(T)Φ_(m)I_(2a),把T_(em)-s等价为I_(2a)-s,对异步机复杂的矩差特性T_(em)-s进行了基于一些定义(功率因数,有功电流等)、定律(欧姆定律,最大功率传输定律等)的直观理解。详细提要请见本文的结语。This paper makes use of the electromagnetic torque′s physical expression T_(em)=C_(T)Φ_(m)I_(2a),lets T_(em)-s be equivalent to I_(2a)-s,and gives the complicated torque-slip characteristic T_(em)-s of induction motors an intuitive understanding based on the definitions such as power factor and active current as well as the laws such as Ohm′s law and maximum power transfer law.The detail abstracts can be seen in the conclusions of this paper.
