a) The motor must start and operate smoothly.
In case this does not occur, turn it off and
check all connections and the mounting
before starting it again.
b) In case there is excessive vibration, check
if the fixing screws are correctly fastened.
Check also if the vibration comes from a
neighbor machine. Periodical vibration check
must be done.
c) Run the motor under rated load for a short
period of time and compare if the running
current is in accordance to the nameplate
current.
5 - MAINTENANCE
Any service in electric machines should only
be carried out when it is completely stopped
and all phases disconnected from the power
supply.

operaTion
5.1.1 - Machines without Grease Nipples
Motors up to frame size 200 are normally
fitted without grease fittings. In these
cases the regreasing shall be done during
preventive maintenance
attention to the following aspects:
 Take motor apart carefully.
 Take all the grease out.
 Wash the bearing with kerosene or diesel.
 Dry the bearings.
 Regrease the bearing immediately.
5.1.2 – Motors Fitted with Grease Fitting
It is strongly recommended to grease the
machine while running. This allows the
grease renewal in the bearing housing.
When this is not possible due to rotating
parts by the grease device (pulleys, bushing,
etc) that offer some risk to physical integrity
of the operator, proceed as follows:
 Turn off the motor
 Clean the area near the grease nipple.
 Put approximately half of the total grease
and run the motor for 1 minute at full speed.
Then turn off the motor and pump in the rest
of the grease.
 The injection of all the grease with the
motor in standstill can make the grease
penetrate into the motor, through the bearing
housing inner seal.
Inspections intervals depend on motor type
and on application conditions.
