Front Traction Motor
The two front traction motors are brushless permanent magnet motors located
directly behind the front wheels. Each motor is attached to an oil filled gear box
with an internal disc brake. Each motor includes a rotary encoder to recognize
the motor speed. The motor controllers are separate from the motors and control
each motor individually. The right side controller (SC5: Traction 1) controls the
right side traction motor and the left side controller (SC6: Traction 2) controls
the left side traction motor. The traction motors receive operation power from
their respective motor controllers. The traction motors are not directly connected
to the CAN bus.
Note:
If a front traction motor is removed or replaced for any reason, the front
traction motors must be calibrated.

Testing the Front Traction Motors
The InfoCenter Display can be used to monitor the current draw for the traction
motors during machine operation. During operation, some variance in the
traction motor current draw is expected even when driving straight.
If traction motor performance is suspect, do the following before testing the
traction motor:
•
Ensure the tire pressures are in balance.
•
Ensure the rear caster fork is in alignment;
Aligning the Rear Wheel Caster
.
•
Ensure the brake system is not engaging (dragging) during operation; refer
to
Adjusting the Brakes (page 6–3)
.
•
Try to calibrate the traction motors; refer to
Calibrating the Front Traction
.
