Maintenance
Motors surfaces must be kept free from accumulations of
dirt in order to make sure sufficient cooling. Now and
again, the connection cable must be checked for abrasions.
After the first two hours of operation the lock screws must
be retightened. Subsequent inspections for tight seating of
the screws shall be performed once a day. The bearings of
our motors need no maintenance in normal cases. These
bearings have a grease filling for life.
In case of wear of the bearing, the motors shall be taken
out of service and the special bearings shall be replaced.
We recommed to send these motors to the manufacturers in
order to have these repaired. Only when doing so you may
be sure to get motors repaired properly.
If you proceed to disassemble the motors yourselves or to
replace bearings, the workplace must be kept clean. No dirt
particles must be allowed to get into the interior of the
motors. Never use cleaning wool, but non-fluffy cleaning
cloths for cleaning motor components.
Never make the motors run without
flywheels, because in such cases the bearings
could be destroyed!
Maintenance of the carbon brushes
After every 250 hours of operation the carbon brushes
should be checked for wear. Remove the protective cover.
Push back the clamping rocker of the carbon brush holder
and carefully take out the brushes out of the holder with a
pair of pliers. Carbon brushes of less than 8 mm length
should be replaced. The wires of the brushes are fitted with
cable terminals and connected to the carbon brush holder.
Make sure that the brush cables cannot get into contact with
the bearing cover during operation. Deposited carbon dust
can be removed with compressed air of not more than 15
psi.
