Abstract

In asynchronous short-circuited engines with a power of 0.6 to 15 kW with a normal rotor cell, there is a change in the total inductive resistance of its equivalent circuit as it runs. Based on the hyperbolic law of variation of the total inductive resistance from the current, the expression for the electromagnetic moment in the function of slip is derived, and expressions for the maximum electromagnetic moment and critical slip are obtained. The proposed calculation method was tested using the example of an A41-4 engine. The results of the calculation of the maximum and initial moments coincided with the results of the experiment.
