2.3.3 External cleaning
The external cleaning of the frame and motor
should be restricted to brushing, sponging or
wiping while the motor is running or is still hot.
Never wash down a separator with a direct water
stream. Totally enclosed motors can be damaged
by direct hosing to the same extent as open
motors and even more than those, because:
•
Many operators believe that these motors are
sealed, and normally they are not.
•
A water jet played on these motors will
produce an internal vacuum, which will suck
the water between the metal-to-metal contact
surfaces into the windings, and this water
cannot escape.
•
Water directed on a hot motor may cause
condensation resulting in short-circuiting and
internal corrosion.
Be careful even when the motor is equipped with
a protecting hood. Never play a water jet on the
ventilation grill of the hood (if any).
