Section 10 - Traction Drive System
ELECTRIC VEHICLE SERVICE
When servicing the electric vehicle always observe the following:
Always turn Power key to OFF, Directional
key switch to Neutral, remove Power key,
block tires and disconnect the battery
negative (-) cable before performing any
vehicle service to avoid accidental startup
of vehicle and possible personal injury.
SAFETY FIRST
TRACTION MOTOR
Maintenance
A good planned maintenance program will save many hours of
future down time and prevent catastrophic failure of major motor
components. Maintenance schedules consist of periodic routine
inspections of motors, battery and wiring circuitry.
Since operation of golf equipment varies widely, the following rec-
ommendations are suggested for periodic maintenance inspec-
tion:
Normal service – 8 hours per day operation
•
Routine inspection every 1,000 hours
Severe service – 24 hours of daily operation
• Routine inspection every 500 hours
NOTICE
Severe service would include; Dusty or sandy locations such
as cement plant, lumber or fl our mills, coal dust or stone-
crushing areas. High temperature areas such as steel mills,
foundries, etc. Sudden temperature changes such as contin-
uous in-door-outdoor movement, as in refrigeration plants.
External Motor Inspection
1. Check for clean, tight, terminal studs and mounting bolts.
2. Internal and external spline drives, between motor and fi nal
drive axle, must be periodically lubricated with a thin layer of
quality, anti-seize compound.
3. Check for any signs of oil leaks from fi nal drive axle, which
might cause oil to enter traction motor.
Internal Motor Inspection
The brush and commutator inspection is the most important part
of motor maintenance. By recognizing undesirable commutator
and/or brush conditions, internal repairs can be performed before
major component damage or failure occurs.
Brush and commutator inspection can be accomplished by re-
moving the motor head. The brushes and commutator should be
inspected for even wear and good commutation.
Good commutation will be indicated by a dark brownish, polished
commutator and an evenly polished brush wearing surface. If the
commutator appears rough, pitted, scored or has signs of burning
or heavy arcing between the commutator bars, the motor should
be removed for servicing.
Traction Motor Removal
NOTICE
Studs and jam nuts on the electric motor can be damaged
when attaching or removing electrical leads. Hold a thin open
end wrench on the electrical stud connector jam nut while
loosening or tightening attaching nuts.
1. Mark traction motor cables (if not already marked), with motor
terminal identifi cation. Figure 10-1.
2. F1 and F2 terminals are 1/4-20 UNC. A1 and A2 terminals
are 5/16-18 UNC. Hold terminal jam nut with a thin open end
wrench when loosening and removing hex nuts, lock washers
and fl at washers securing electrical cables to traction motor.
