Abstract

Electric energy is one of the most important products in a modern developed society. Electric motors of various purposes are considerable proportion among electric power consumers. The development of recommendations for the selection of rational operating modes for electric drives of process units in terms of their energy parameters, which include power and energy losses, efficiency factor, power factor, is certainly a topical issue.

In the article, the feasibility of increasing the power factor with a decrease in the load factor of the drive motor is investigated.

Wide range of technological processes for the repair of rolling stock was analyzed, during which was established that most of the equipment works with a load factor of less than 0.5 for a long time. It is proved that a rational way to increase of  these electric drives is to switch the stator windings from the "triangle" to the "star".

Method for determining the minimum load factor for the electric drive of a process equipment, at which the power factor lies within the limits of the quality assessment "good" and "excellent" is proposed.
