MASTER DRIVE UNIT
The heart of the traction system is the master drive
unit (MDU). A stationary traction motor eliminates the
power cables from the traction motor to the traction
controller from rotating or flexing. The MDU features
an integrated pinion with a splined motor to MDU cou-
pling. The support bearings and pinion are integral to
the MDU eliminating the potential of damaging the
gears when assembling the motor to the MDU. By in-
tegrating the pinion, the gear mesh can be better con-
trolled resulting in a quieter MDU. The splined cou-
pling allows for quick removal and installation of the
traction motor.
