Lubrication Interval of Motor
Timely lubrication also leads to lower breakdown of motors.
Below is the lubrication interval of the motor.
Vibration Level In motors:-
Vibration
of an electrical machine is closely related to its assembly on the application
and, thus, it is generally desirable to perform vibration measurements under installation
and operational conditions. Nevertheless, to allow evaluation of the vibration
generated by the electrical machine itself in a way to allow reproducibility of
the tests and the obtaining of comparative measurements, it is necessary to
perform such measurements with the machine uncoupled, under controlled test
conditions. The test conditions and vibration limits described here are those
found in IEC 60034-14.
The
severity of vibration is the maximum value of vibration found among all the
recommended measurement points and directions. The table below indicates the
recommended admissible values of vibration severity under IEC standard 60034-14
for the frames IEC 56 to 400, for degrees of vibration A and B.
