近年来,国产的森兰变频器采用了一种名为“拟超导”的新技术,在改善异步电动机变频调速的机械特性方面,取得了令人满意的结果。 一、基本指导思想 异步电动机在变频调速过程中及在负载变化时,机械特性不够理想的根本原因是定、转子绕组的电阻要消耗功率,并且所消耗功率的大小及其在能量的传递和转换过程中所占的比例均非常数,从而影响了电动机的带负载能力及运行的稳定性。
In recent years, the domestic Senlan inverter uses a new technology called “to be superconducting”, and has achieved satisfactory results in improving the mechanical characteristics of the variable frequency speed control of induction motors. First, the basic guiding ideology Asynchronous motor in the frequency control process and load changes, the mechanical properties of the root cause is not enough, the rotor winding resistance to power, and the size of the power consumed and its energy transfer and The proportion of conversion process are non-constant, thus affecting the load capacity of the motor and the stability of the operation.
