Caution! Charger is not allowed to be used if there is water in it.
Caution! Use the charger when the environment temperature is between -10 to +45 Celsius Degrees
WARNING!
Only qualified electrician is allowed to open the housing of the charger.
WARNING!
When charging the batteries, hydrogen will be generated, so it’s important to keep the charging area in a
safe and dry room with good ventilation; and also to avoid any fire and spark.
5.3 Maintenance of the Traction Motor
WARNING! There should be No explosive gas vapor in the air, otherwise, it may cause serve injury
and damage to your body and property if the explosive gas vapor contacts the sparks generated
from the motor.
1)
For DC motor, the carbon brush should be checked every 3 months to see if it is worn or not, as it is an
easily worn part. If it is not replaced in time before it becomes worn out, it will damage the motor badly.
The brush spring should also be checked when checking the carbon brush.
2)
Do not keep the motor running idly for long periods of time. Any idle running of the motor should be
avoided.
3)
Removal of mud, sand and other clinging objects shall be done frequently to distribute the
heat-radiation.
4)
Periodically use the low pressure air to remove the dust from the carbon brush and the commutator.
Periodically check the connection of the carbon brush and the commutator.
Main malfunction symptoms and possible causes of the DC motor
Item Symptoms Possible Causes
1 All copper plates turn
black. The pressure of the brush is incorrect.
2 The commutating
copper turns black in a
certain order and in
groups. Short circuit happens between the commutating copper or among
the armature coil; poor welding or disconnection happens between
the commutating copper and the armature coil.
3 The commutating
copper turns black
disorderly. The central line of the commutator deviates or its surface is not
round and not smooth.
4
The brush wears out,
changes colors and
breaks.
The motor vibrates; the clearance between the brush and its holder
is too big; the clearance between the brush and commutator is too
big; the mica between different commutators comes out; the brush is
made of wrong materials; the brush is wrong in type.
5 Big sparks
The motor is over-loaded; the commutators are not clean, not round
or not smooth; mica or some commutator are coming out; the brush
is not ground properly; the brush is under a lot of pressure; the brush
is wrong in type; the brush is jammed in the brush holder; the brush
holder becomes loose or vibrating; the polarity and sequence of the
magnetic poles becomes wrong.
6
The brush and its wires
get hot. Big sparks from the brush; poor contact between brush and soft
wires; only a small section area of soft wires.
7 The brush is noisy The surface of the commutator is not smooth.
CAUTION!
Only a qualified technician is allowed to perform the maintenance on the motor.
