The traction motor blower is an 83-horsepower, AC motor-driven blower that provides cooling air of 18,600 to 20,000 CFM at Notch 8 engine speed for all the traction motors on the locomotive.

2
00:00:15,375 --> 00:00:24,167
A minimum flow of 2,775 CFM at Notch 8 engine speed is provided to each traction motor.

3
00:00:24,167 --> 00:00:31,042
Some of the cooling air also flows across the AC motor on the traction motor blower to keep it cool.

4
00:00:31,042 --> 00:00:40,667
Whenever the engine and the auxiliary alternator are operational, the traction motor blower runs to maintain positive pressure in the traction motors.

5
00:00:40,667 --> 00:00:45,417
This prevents dirt and moisture from contaminating the traction motors.

6
00:00:45,417 --> 00:00:54,333
The Traction Blower Controller determines the speed of the traction motor blower based on calculated motor temperatures and motor currents.

7
00:00:54,333 --> 00:00:58,292
Motor speed is either half or full engine speed.
