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.
