General
The electric motor characteristics are given
on the nameplate xed to the motor itself.
Cooling
The main motor has a fan aiming at
guaranteeing adequate cooling. The same
fan guarantees also the cooling of the
compressor.
Abnormal noises
Any vibration or abnormal noise is usually
due to deterioration of the bearings. In
this case it is recommended to replace the
bearings rather than risking more serious
problems to the motor or the machine.
Electrical checks
If the machine has been stored for a long
period or in case of long stops in damp
places, it is suggested to measure the
winding insulation value by applying 500 V
d.c. voltage for 60 seconds.
The insulation should be at least 10 M
(MegaOhms) in warm conditions or 100 M
in cold conditions.
Should these values not be detected and in
case the motor has been exposed to damp,
it is suggested to dry it for 24 hours in a
furnace at 100-110 °C.
If no furnaces are available, please contact
the manufacturer.
