Windings
For long life, keep windings clean and dry. Dirt or dust can be removed by
wiping them with a clean cloth, by blowing with clean, dry, low pressure air
or by vacuum cleaner. Oil or grease can be removed with a cloth moistened
with mineral solvent. Be sure not to get any solvent on the commutator and
observe all product warnings.
Filters – Cleaning
When supplied, filters on motors must be kept clean to assure proper air
flow and cooling of the motor. The following procedure should be used to
clean these filters:
1. For light accumulations of dust, use compressed air to clean.
2. For moderate accumulations, water may be used.
3. For heavy accumulations of dirt and grease, clean the filter using water
and detergent.
4. Always completely dry filter after cleaning with water.
5. After heavy cleaning, spray with a very light coat of protective oil to
protect against possible loss of plating.
Important: Do Not use flammable solvents to clean filters.
Important: Standard washable filters may not be suitable for motors
operating in atmospheres with heavy concentrations of oil mist.
Oil mist may be drawn into the motor and cause damage to the
commutator and windings. Contact Allen-Bradley for motors
operating in heavy oil mist atmospheres.
Brakes
Motor mounted brake, when supplied, must be adjusted and maintained in
accordance with the instructions for the specific brake. Refer to separate
instructions supplied with the motor
Disassembly & Reassembly
Instructions The motor design incorporates many new techniques which are described in
this section. It is recommended that these differences be understood
thoroughly before any disassembly work is done to avoid possible damage
or harm to either machine and/or maintenance personnel.
