4 AC Induction Motors
Storage
Motors must be stored in a clean, dry area protected from extremes of
temperature, moisture, shock and vibration. Storage temperatures of
10 to 49 degrees C (50 to 120 degrees F) with a maximum relative
humidity of 60% must be observed. In addition, motors subjected to
extended storage must be handled and treated per the requirements
specified in publication “Motors-5.0.” This publication is available
from your Allen-Bradley Sales Office or online at:
http://www.controlmatched.com.
All drains to be fully operable while in storage, and/or the drain plugs
removed. The motors must be stored so that the drain is at the lowest
point. All breathers and automatic “T” drains must be operable to
allow breathing at points other than through the bearing fits.
Installation Allen-Bradley AC motors are designed and built in accordance with
Safety Standard for Construction and Guide for Selection,
Installation and Use Of Electric Motors And Generators published by
the National Electrical Manufacturers Association (NEMA),
publication MG-2-1983 (ANSI C51.5). It is recommended that this
publication be referred to whenever you select or install any AC
motor.
The application of motors and other electrical equipment in
hazardous locations is restricted by the National Electric Code. Users
must observe these regulations and consult with local code inspection
and enforcement agencies to insure compliance.
Location
Locate the machine where the ambient temperature is not over 40
degrees C (104 degrees F) and where clean air has free access to
ventilating intake and outlet openings. Except for machines with a
suitable protective enclosure, the location should be clean and dry.
Important: The cooling system on standard totally enclosed, blower
cooled motors requires clean air to be forced through ducts
which are integral to the stator frame. It is important that
these air passages be kept clean and that sufficient
clearance be provided on the blower motor air inlets and
stator duct outlets for unrestricted flow of air.
For Drip-Proof Force Ventilated Enclosures, sufficient clearance must
be provided on all inlet and outlet openings to provide for unrestricted
flow of air. Separately ventilated motors with exhaust to ambient
(pipe-in only) must have at least 152.4 mm (6 in.) of clearance
between the opening and adjacent walls or floor.
Important: Motors located in a damp, moist environment must have
space heaters to protect against condensation when motor
is not operating.
