Abstract
EN: The article discusses one of the options to reduce the electricity consumption for the
carry out acceptance of post-repair tests of traction electric machines. Heating tests of traction
electric machines at the mutual load stand are the most energy-intensive part of the entire test
program. Energy consumption for this type of test can be reduced, for this, an analysis of
thermal processes in the windings of traction electric machines during their heating test was
given. The energy efficiency coefficient of the mutual load system is formulated. The energy
efficiency coefficient for the traction electric machine NB-406 is calculated. The calculation
results showed that with an increase in the test current by 30%, the total losses in the motor
windings decrease by about one and a half times, while the test time decreases by almost three
times. An increase in test current and a decrease in test time do not reduce the quality of the
test, and the results obtained. A methodology for assessing the energy efficiency of heating
tests is proposed. It can be applied at test sites of depots, as well as repair plants. This will
reduce the material costs of testing, without compromising the quality of the tests themselves.
