3 INSTALLATION
Electric motors should be installed in locations of easy access for inspection and maintenance, specially on bearings
(relubrication), inspection of brushes, etc. If the surrounding atmosphere contains humidy, corrosive or flammable
substances or particles, it is essential to ensure an adequate degree of protection.

Under no circumstances, motors can be enclosed in boxes or covered with materials which may impede or reduce the free
circulation of cooling air. Motors fitted with external cooling must be located at least 50mm from the ground to permit free air
circulation. The air inlet and outlet should never be obstructed or reduced by conductors, pipes or other objects. The
installation site should permit conditions of air renewal at a rate of 200m³ per minute for each 100 kW of motor output.


3.1 MECHANICAL ASPECTS
3.1.1 Foundations

The motor base must be leveled and free from vibrations.
For this reason, concrete foundation is recommended.
The type of base to be built will depend on the nature of
the soil at the installation site or on the floor capacity.
When designing motor foundation, it must be taken into
consideration the fact that the motor might, occasionally,
be submitted to a torque higher than the rated torque. If
such designing is not correctly made, vibration problems
can occur in the unit (foundation, motor and driven
machine).


            ATTENTION
            On the concrete base, a metallic plate to
            support the leveling bolt must be provided.


Steel or iron blocks, plane surfaces blocks with
anchorage devices can be fitted in the concrete
foundation to fix the motor feet as suggested in figure
3.1.
It is important that all the structure equipment are made
in such a way that they can transmit any force or torque
which may occur during the operating.

coupling due to lower cost, less space required, no belt
slippage and lower accident risk.                             The correct positioning of a pulley is shown in figure 3.9.
In case of speed ratio drives, it is also common to use
direct coupling with a gearbox.


             ATTENTION
             Align carefully the shaft ends using, whenever
             possible, flexible coupling.

shaft alignment, perfectly parallel in cases of straight
gears, and at the correct angle for bevel or helicoidal
gears.
Perfect gear arrangements can be checked by inserting a
strip of paper on which the teeth marks will be traced
after a single rotation.

c) Belt/pulley coupling
Belt transmission is the most commonly used when a
speed ratio is required.

ASSEMBLY OF PULLEYS: The assembly of pulleys on
shafts featured with keyway and threaded hole must be
done by inserting it halfway up to the keyway merely by
manual pressure.
On shafts without threaded hole it is recommended to
heat up the pulley to about 80ºC (figure 3.7).
Hammers should be avoided when fitting pulleys and
bearings. The fitting of bearings with the aid of hammers
causes spots in the bearing races. These initially small
spots increase with usage and can develop to a stage          Figure 3.10: Correct pulley alignment.

3.2 COMMISSIONING

3.2.1 Preliminary inspection

Before starting a DC motor for the first time, or after long
period of standstill, check the following items:
1. Is motor clean? Were all packing materials and
     protection elements removed?
2. Are coupling elements in perfect conditions and duly
     tightened and greased, where required?
3. Is alignment correctly made? (as per item 3.1.2).
4. Are bearings duly lubricated for perfect operation?
     (as per item 4.8.2)

4 MAINTENANCE
A well-programmed maintenance schedule of DC motors, when correctly used, includes a periodical inspection of insulation
levels, bearing lubrication and useful life, vibration levels, wear of brushes and commutator as well as brush holder
conditions.
Frame must be kept clean, free of dust, oil and dirt in order to make the cooling process easier.
In case one of the above items are not followed accordingly, you might have unexpected stops of the equipment. Inspection
cycles depend on the type of motor and the conditions under which it operates.

FINE ADJUSTMENT

1. After adjusting neutral zone (coarse adjustment),
   connect motor with rated voltage (rated voltage, if
   possible);
2. Check both rotation directions. Difference can not be
   bigger than 1%;
3. In case difference is bigger than 1%, check to see in
   which direction the speed is higher. To decrease
   speed, turn brush holder ring in the same direction of
   the motor turn;
4. To increase speed, at a certain direction, turn brush
   holder ring to the opposite direction of the rotor turn.

4.4 CHECKING OF COMMUTATION
A well-succeed commutation is understood as the quality
of commutation which does not affect commutator and
brushes, neither motor operation.
Absence of sparking does not mean assencially a good
commutation.
To verify commutation, you must hook up load to the
motor and check for sparking trying to see if this is normal
or not. If abnormal sparking is noticed, from level 1¾ (see
table 4.2), find cause(s) and eliminate it. Sparking
originated from unsatisfactory commutation can have
mechanical causes such as motor vibration, commutator
deformation, incorrect brushes pressure, etc. Also
electrical causes such as poor contact between brushes
and commutator, problems on the commutation pole
winding or in the armature, current peaks, disadjusted air
gap, etc.. and physic-chemical aspects such as excessive
air humidity or steams or corrosive gases or oil or dusts on
the commutator can generate sparking.
The air gap of commutation poles (for extractable pole
motors) is adjusted at the factory, same as neutral zone.


            ATTENTION
            If poles must be extracted, then original air
            gap have to be respected accordingly at the
            time of the assembly. Also brush holder ring
            must be adjusted to neutral position (see          Figure 4.2: Sparking level
            items 4.3 and 4.4).

Based on the type of cooling system, WEG DC motors               4.8.2 Air filters for DNA, DCA, DNW and DCW
can be divided in several groups as follows:                           models
     Self-cooling (DNS/DCS type);
     Forced cooling (DNF/DCF and DNX/DCX types);
     Without cooling (DNE type);                                                                               Filter
     Air-air heat exchanger (DNA+DCA type);
     Air-water heat exchanger (DNW+DCW type).

Rotation direction of the fan must be checked (following
the indicating arrow). An operation with reverse rotation
reduces considerably the air flow resulting in motor
overheating. Therefore, any object that can impede free air
circulation internally and externally should be eliminated. In
case of air-air heat exchanger motors which can be
supplied with thermostats, air flow detectors, filters, etc.,
these should be tested for perfect operation. On air-water
heat exchanger motors, make sure correct water flow              Figura 4.7: Air filters model (DNW and DCW)
specified for radiators is circulating accordingly.
Forced cooling motors, when cooling is made by ducts,
any impurity accumulated inside these cooling ducts
during assembly services (maintenance or in operation)
must be removed before operating the motor. Motor
requires pure and humid air (not totally dry as this can
damage the brushes).
