Directions of improvement of cooling systems of traction electrical machines of the locomotive
This article presents the peculiarities of different types of cooling systems of traction electrical machines of lo- comotives. The estimation of efficiency of different types of cooling systems is given.It is shown that the reliability of the central cooling system depends on the reliability of the fan that operating this system.To improve the reliability of such systems it is proposed to install an additional fan, which can operate in paral- lel with the main fan
