Cooling
BLADE series electric motors are self-ven-
tilated.
It is necessary to check that no dirt has ac-
cumulated on the rear cover of the motor.
Dirt could restrict the cooling air fl ow.
Irregular Noises
Any abnormal vibrations or noises usually
depend on worn bearings. In such an event,
it is suggested to replace the bearings.
Electrical Checks
If the machine has been stored for long pe-
riod or in the case of long stops in damp
places, it is recommended to measure the
winding insulation value by applying 500 V
c.c. voltage for 60 seconds.
Insulation should be of at least 10 MΩ (Me-
gaOhms) in warm conditions or 100 MΩ in
cold conditions.
Should these values be not detected and
the motor has been exposed to damp, it is
recommended to dry it for 24 hours in a fur-
nace at 100-110 °C.
If no furnaces are available, please contact
the manufacturer.
WARNING !!!
Before starting the machine, verify
that the nuts blocking the power
supply cable terminal boards are
well tightened.
