Class 22X traction motor testing

Working with an associate (Rubirail), Pindari has developed a method of testing Class 22X traction motors at varying speeds to test the airflow through the motor as a means of investigating premature bearing failures caused - it is believed - by overheating.


The rig allows the motor to be run at any speed between (the equivilent road speed of) 15mph and 125mph whilst flow measurements are taken in complete safety.


From these tests Rubirail has been able to generate a detailed analysis of air flow through the motors (including a previously unknown tendancy to recirculate cooling air) and determine a number of potentially improved cooling solutions.
