Abstract

Analysis of cataloged data of crane asynchronous motors of the MT and MTK series is performed to verify the cataloged data reliability and compliance with the general laws of parameter variations depending on the nominal power of the motor. Analytical expressions for determining magnetic and mechanical losses as a share of total losses are obtained. These expressions are necessary to calculate the parameters of the equivalent circuit. The program developed in the Mathcad environment makes it possible to determine six unknown parameters, the resistances of the equivalent circuit, to maintain the balance of active and reactive powers. The results of calculations of the equivalent circuit parameters of all motors are given, which makes it possible to construct mechanical characteristics.

异步起重电动机的分类数据分析和等效电路参数的确定

摘要

对MT和MTK系列起重机异步电动机的分类数据进行分析，以验证分类数据的可靠性以及是否符合电机额定功率下参数变化的一般规律。获得用于确定磁损耗和机械损耗占总损耗份额的解析表达式。这些表达式对于计算等效电路的参数是必需的。在Mathcad环境中开发的程序可以确定六个未知参数（等效电路的电阻），以保持有功功率和无功功率的平衡。给出了所有电动机等效电路参数的计算结果，这使得构造机械特性成为可能。
