| Popis: | The research subjects are asynchronous motors of the type ATM4 in the power range from 400 to 8000 kW produced by NPO “ELSIB” PAO. The article proposes a method for optimizing the calculation of heating parts of the active volume of large asynchronous motors in the short-circuit mode of the engine. The calculation method is based on the fundamental provisions of the theory of electric machines. The purpose of the study is to automate the calculation of heating different parts of the active volume of the motor. The calculation of heating is determined by the need to preserve the operability of the motor in the event of emergency situations in production. The originality of the study lies in the fact that the algorithm for calculating the time to achieve critical heating of various parts of the active volume of the asynchronous motor is modified based on known positions. This provides the correct protection against the effects of thermal overheating. The results of the study are presented on a specific example of the motor. |
