8720SM AC Motor
Overview
8720SM -
The 8720SM motors are high performance AC induction motors
specifically designed for use with the Allen-Bradley 8720MC Drives.
Refer to the configurator below to help identify your 8720SM motor.
The customer is responsible for inspecting the equipment before
accepting the shipme nt from the freight company. Check t he items
against your purchase order.
Handling
The 8720SM motors are equipped with lifting eye bolts. These eye
bolts are provided to assist in handling and mounting the motors. The
motors can accommodate either flange or foot mount.
ATTENTION
Eyebolts may unscrew during lifting. Check the
eyebolts to insure that they are tight. Failure to
observe this precaution could result in bodily injury.
!
Storage
Store motors in a clean, dry area protected from extreme
temperatures, moisture, shock, and vibration. Observe storage
temperatures of -20° to 80° C (-4° to 176° F) with a relative humidity
of 5 to 95%.
IMPORTANT
ATTENTION
!
The application of motors and other electrical equipment in hazardous
locations is restricted by the National Electric Code. To ensure
compliance, observe these regulations and consult with local code
inspection and enforcement agencies.
All drains are fully operable while in storage. Store
motors so that the drain is at the lowest point. Dr ains
are located in the lower po rtion of the motor c astings
on both the drive and non-drive ends of the motor.
Only qualified electrical personnel familiar with the
construction and operation of this equipment and the
hazards involved should in st al l, adjust, operate, and/
or service this equipment. Read and un de rstand this
document in its entirety before proceeding. Failure to

8720SM High Performance AC Induction Motors5
Before Mounting Your
Motor
Before mounting your 8720SM motor, consider the following:
•
You can mount the motor horizontally or v e r tically with t h e sh aft
down or up.
•
The 8720SM motors are blower cooled with air flow from the
blower end to the drive end. The air flow must be flowing in the
direction of the arrow on the motor to provide adequate cooling.
Both air inlets and outlets must be free of obstructions. Maintain a
clearance of at least 100 mm (4 in.) at the bl ower inlet area.
•
When mounted, the motor must not be exposed to direct splash
or spray of cutting fluids or lubricatin g oils.
•
Motors include a labyrinth type shaft seal with flinger, which helps
protects against splashing. However, it will not provide protection
against flooding.
•
In an environment where high humidity is present or the motor
blower inlet air is saturated with coolant mist, make sure the
motor is mounted with the feet down and the drain holes at the
bottom of the motor are open.
•
The motors are designed for the ambient temperature i ndicated on
the nameplate. The standard motor maximum ambient is 40° C
(104° F). Locate the motor where the ambient temperature
require m ents are sat isfied and wh ere clean air has fre e access to
ventilating intake an d outlet openings . Except for machines w ith a
suitable protective enclos ure , t he locat i on should be clean and
dry.
IMPORTANT
ATTENTION
!
The cooling system on standard 8 7 20S M bl owe r
cooled motors requires that clean air is forced
through ducts which are integral to the stator frame.
It is important that you keep these ai r passages clean
and that sufficient clearance is provided on the
motor air inlets and stator duct outlets for
unrestricted air flow.
Y ou must be careful to prevent debris (such as metal
shavings and conduit knockouts) from falling into
the motor while performing any installation work
around the motor. A hazard of personal injury and/or
equipment damage exists if foreign material lodges
inside the motor.

Using Belted Driv es and Coupled Drives
Proper alignment is key for long life of bearings, shafts and belts, and
minimum downtime.
Belted Drives
If you use motor slide bases or rails, you must securely anchor them
to the foundation with the proper bolts. Make sure the motor shaft
and load shaft are parallel, and that the sheaves are aligned.
When a motor is belt coupled, the belt tension must not exceed the
radial load capabilities of the motor beari ngs. For belt drives, place the
sheave as close as possible to the motor bracket. The maximum
allowable radial load is assumed to be applied at the end of the motor
drive shaft.
IMPORTANT
Do not exceed the maximum allowable radial load
on the end of the shaft. Refer to the Radial Load Force Ratings (Zero Axial Load) on page 25 for a
listing of radial loads .
Coupled Drives
Use flexible couplings between the motor shaft and the load shaft.
Align the motor shaft and the load shaft to values recommended for
the specific coupling before coupling is connected.
IMPORTANT
Do not exceed the maximum allowab le axial load on
the end of the shaft. Refer to the Axial Load Force Ratings (Zero Radial Load) on page 26 for a listing of
axial loads.
Balancing the Motor
Misalignment can cause excessive vibration and damaging forces to
the shaft and bearings. During high speed operation, a small
unbalance can cause significant vibration. Make sure to accurately
dynamically balance any gears, pulleys, or couplings that are mounted
to the motor shaft. Best results are obtained by balancing after the
device is mounted to the shaft.
Publication 8720SM-IN001A-EN-P — February 2003
Motors are dynamically balanced to stay wit hi n a vibration l imit of
0.12 in./s, measured in accordance with NEMA MG-12.06. Balance is
done with a full leng th 1/2 height shaft key. A full shaft key is s hipped
8720SM High Performance AC Induction Motors7
with the motor. Sheave or coupling should be balanced with a 1/2
height shaft key.
Preventing Electrical Noise
Use Electromagnetic Compatibility (EMC) techniques to reduce
Electromagnetic Interference (EMI), commonly called noise. Noise
adversely impacts motor performance by inducing stray signals.
Effective techniques to counter EMI include filtering the AC power,
shielding and separating signal carrying lines, and practicing good
grounding techniques.
To help avoid EMI:
•
Filter AC power by using isolated AC power transformers or
properly installed AC line filters.
•
Physically separate signal lines from motor cabling and power
wiring. Do not r oute signal wires with motor and power wir es, or
over the vent openings of servo drives.
Building Your 8720SM
Motor Cables
•
Ground all equipment using a single-point parallel ground system
that employs ground bus bars or large straps.
Refer to System Design for Control of Electrical Noise Reference Manual (GMC-RM001x-EN-P) for information on additional electrical
noise reduction techniques.
Proper cable construction and routing improves system
ElectroMagnetic Compatibili ty (EMC). Refer to the 8720MC High Performance Drive Installation Manual (publication
8720MC-IN001x-EN-P) for information regarding cable const ruct i on.

Guidelines for Installing
Your Motor
Observe the following for installing your motor:
ATTENTION
!
•
Allow sufficient clearance in the area of the motor for it to stay
within its specified ope r ating temperature as well as protected
from direct splash or spray of cutting fluids or lubricating oils.
Refer to Before Mounting Your Motor for additional information.
•
Refer to Using Belted Drives and Coupled Drives to determine
proper installation in r ega rd to using belted and coupled drive s .
•
Mount your motor on a rigid, solid base, or foundation. Poor base
construction may cause resonances i n the motor/base assembly,
which can result in bearing failure and other motor damage. Use
the correct grade of hold down bolt s for the type of mounting.
Refer to Specifications for recommended bolt torque values.
Only qualified electrical personnel familiar with the
construction and operation of this equipment and the
hazards involved should in st al l, adjust, operate, and/
or service this equipment. Failure to observe

Motor Load Force Ratings
Motors are capable of operating with a sustained shaft load. The radial
and axial load force locations are shown in Figure 11, and the
maximum figures are in the tables.
Figure 11
Load Forces on Motor Shaft
Radial load force applied at center of shaft extension
Axial load force
The tables represent 10,000 hour L10 bearing fatigue life at various
loads and speeds. The 10,000 hour life does not account for possible
application specific life reduction that may occur due to bearing
grease contamination from external sources.
