Abstract

At present, existing stands for testing traction electric machines do not differ in their high energy efficiency, which results in significant electricity consumption during testing. The article presents the results of the analysis of the influence of load current of traction electric machines during their testing on heating on total electric energy consumption for testing. On the example of electric motors NB-406 and DT-9N analytical and graphical dependences of the energy efficiency coefficient and time of the test on the load current are obtained. It is shown that increasing the load current when tested for heating allows to significantly reduce the cost of electricity, as well as reduce the test time without reducing its quality. The results of the theoretical and experimental studies can be used to reduce the cost of electricity and time during the testing of traction electric vehicles rolling stock.
