To ensure reliable operation of electric motors and their efficient use during operation, data from modern modeling tools and calculated reliability indicators. The obtained modeling and calculation results are necessary to adjust the existing or create a new strategy for technical system equipment maintenance. The paper offers practical recommendations for increasing the accuracy of reliability indicators by taking into account real operating conditions when calculating the hazard rate of an electric motor during its normal operation. For this purpose, when calculating the hazard rate of an electric motor, λeq is used, where individual coefficients take into account the influence of possible external and operational factors and modes during the operation period. Clarified data on the hazard rate values allow us to obtain values of a number of reliability indicators close to the actual ones, and to plan rational terms for performing maintenance of an electric motor or its individual elements. This is important to ensure reliable operation of equipment using electrical machines.
