00:00:00,000 --> 00:00:11,375
The high adhesion truck uses three AC (5GEB13) or DC (5GE752AH) traction motor combos.

2
00:00:11,375 --> 00:00:23,542
The nose of each combo is resiliently mounted to the truck frame with a motor nose suspension, and ends of the combo are allowed to float in the truck frame with a journal housing and nylon wear liners.

3
00:00:23,542 --> 00:00:28,500
This holds the combo in the truck in a triangle-shaped configuration.

4
00:00:28,500 --> 00:00:33,625
Electricity is supplied to the traction motor from the propulsion system.

5
00:00:33,625 --> 00:00:39,125
Coils in the traction motor create a magnetic field, which causes the rotor to turn.

6
00:00:39,125 --> 00:00:44,583
On the rotor, the small pinion gear meshes with the larger bull gear on the axle.

7
00:00:44,583 --> 00:00:53,500
Depending on the traction motor design, the pinion gear may either be formed as an integral part of the rotor or may be pressed onto the rotor.

8
00:00:53,500 --> 00:00:58,833
The bull gear is pressed onto the axle along with the two wheels and the U-tube.

9
00:00:58,833 --> 00:01:10,042
Two roller-bearing assemblies allow the axle to rotate freely within the U-tube while the two journal bearings allow the axle to rotate freely within the journal box mounted to the truck.

10
00:01:10,042 --> 00:01:17,875
With the traction motor powered, the pinion and bull gears mesh, causing the axle and wheels to turn and power the locomotive.
