基于转子整流状态研究串级调速机械特性

Study on Mechanical Characteristics of Cascade Speed Control Based on Analysis of Rotor Rectifier State

本文结合转子整流电路中由于转子漏感所引起的换流重叠及换流延迟等特殊工作状态,给出一种串级调速机械特性的定性分析和研究型教学方法。其主要特点是整个分析过程,避开繁杂的数学推导,突出机电作用的物理意义,更有利于学生深入掌握机械特性的物理实质和作用机理。

In this paper, a qualitative analysis and research-oriented teaching method is proposed by combing spe- cial working states in rotor rectifier, such as commutation overlap and commutation delay because of rotor leakage inductance. Its main feature is that the whole analytical process can keep away from complicated mathematical deri- vation and highlight the physical meaning of the electromechanical interaction, which can help students understand in depth the mechanical characteristics of the physical essence and mechanism.
