Operation
Once the Hyponic® unit is installed, ensure that the wiring is correct and secure prior to operation. Observe the
precautions listed in
Table 8
during the trial run. Stop running the gearmotor if any abnormalities are detected and
contact your nearest sales office or distributor.
Observation
Possible Cause
Any abnormal
noises or
vibrations
1. The casing is distorted due to an uneven mounting surface.
2. The gearmotor is resonant due to insufficient rigidity of the mounting surface.
3. The shaft of the Hyponic® and the driven machine are not aligned.
4. Vibrations of the driven machine are conveyed to the gearmotor.
5. Rigidity of the driven machine and its shaft is insufficient (hollow shaft type).
6. Excessive force is exerted on the baffle sections of the torque arm (hollow shaft
type).
7. After the Hyponic® unit is flange or foot mounted, undue force is exerted between
the gearmotor and its shaft.
Abnormally high
temperature of
the gear casing
or motor frame
surface.
1. Motor electric current is exceeding the rated value specified on the nameplate.
2. Is voltage applied between THREE motor connections equal to the motor
nameplate voltage rating ± 10%?
3. The ambient temperature around the unit is too high.
Table 8. Trial Run Precautions
Daily Inspection and Maintenance
1.
Inspect the gearmotor daily for each of the items listed in
Table 9
.
2.
If any abnormalities are found during daily inspections, follow the procedures outlined in the Troubleshooting
Guide,
Table 18 on page 32
. If the abnormality is not listed or the recommended procedure does not solve the
problem, contact your nearest sales office or distributor.
3.
The Hyponic® unit does not require grease replenishment, but overhauling after 20,000 hours of operation, or 3 -
5 years will extend its life.
Items
Details
Electric Current
Is the electric current higher than the value specified on the nameplate?
Noise
Is the gearmotor making any unusual sounds?
Vibration
Are there any unusual vibrations of the gear or motor frame?
Surface Temperature
Is the surface temperature of the gear case, or motor frame too high or rising
suddenly? (The temperature rise during operation varies depending on the
type of motor. There may be a problem, if the temperature frequently rises
approximately 40°C (104°F) above the ambient temperature.)
Grease Leakage
Is there any grease leaking from the gear assembly?
Mounting Bolts/Torque Arm
Are there any loose mounting bolts?
Chains and V-belts
Are there any loose chains or V-belts?
Brake
Is the brake lining worn out?
Is the air gap within specification?
