1. The operating environment should always be kept dry, the surface
of the motor should be kept clean, and the air inlet should not be
obstructed by dust, fibers, etc.
2. When a protection alarm occurs, the cause of the failure should
be found out, and the operation can only be put into operation
after the failure is eliminated.
3. When the machine is stopped for inspection, the operation can
only be carried out after the motor has completely stopped.
4. In order to ensure good lubrication of the motor during
operation, the motor should run for about 4000 hours, that is, the
grease should be supplemented or replaced (the closed bearing does
not need to be replaced during the service life). When the bearing
is found to be overheated or the grease deteriorates during
operation, The grease should be replaced in time. When replacing
the grease, remove the old grease and clean the oil grooves of the
bearings and bearing caps with gasoline. For motors with a speed of
1500r/min and below, refill the bearing grease type for medium and
small motors bearing grease No. 2, and fill the inner and outer
rings of the bearing About two-thirds of the gap between the
bearings; the motor speed of 2500r/min and above is filled with
bearing grease type HTHS, which fills about one-half of the gap
between the inner and outer rings of the bearing.
5. When the life of the bearing is over, the vibration and noise of
the motor will increase obviously. Check that the radial clearance
of the bearing reaches the value in the table below, and the
bearing should be replaced.
Storage and transportation of electric motors:
1. The motor should be kept dry during storage to avoid sudden
changes in ambient temperature.
2. The storage of the motor should not be too high to avoid damage
to the lower motor.
3. The motor should be prevented from tipping or inverting during
storage and transportation.
