Receiving Instructions
· Inspect the shipping container for damage before accepting the motor from
the carrier. Immediately report in writing any observed damage to the carrier.
· Check the motor nameplate data (HP, RPM, voltage, frame size, space heater,
enclosure, etc.) before start-up.
· If a shaft locking device/transit clamps for frames (284T-586/7) are
installed on the motor for transport, remove these and retain for future use.
Reinstall again when transporting motor.
· Turn shaft by hand to be certain it rotates freely and listen for any sounds
of mechanical resistance like the fan rubbing on the fan cover. Check for
debris or loose parts in the fan cover.
Warning
Safety precautions must be observed before installing, using, servicing and
handling any WorldWide Electric motor.During the installation and operation of
our motor in an industrial application, there is a danger of live electric
parts and wires as well as hot surfaces and rotating parts. Therefore, please
carefully read, fully understand, and heed all instructions, warnings,
cautions and safety notices. Failure to do so could lead to personal injury,
death and /or property damage.
Please review the following safety precautions:
· High voltage, rotating machinery and hot surfaces can cause serious or fatal
injury if the motor is improperly installed. Only properly trained, qualified
personnel should perform installation, operation and maintenance on equipment.
Responsible personnel should be familiar with NEMA MG-2, National Electrical
Code, CSA C22-100 (C.E.C), IEC 364 (prEN5011-1) and all state and local
utility regulations and safety standards.
· When preparing to service the motor, all power sources to the motor and
accessory devices must be de-energized and disconnected and made inoperative.
Allow all rotating parts to come to a stop before servicing. Keep extremities,
hair, clothing, foreign objects, etc. away from machinery. Replace Junction
Box cover after connection.
· Before the motor is re-energized, make sure that all safety guards are in
place and that the shaft key is removed before running the motor without a
connected load.
· When working near machinery with high noise levels, proper protection must
be used to reduce harmful effect to hearing.
· Automatic reset/thermostat protection should not be used where an unexpected
automatic restart would be hazardous to personnel. Serious personal injury or
death could occur.
· The frame of the machine must be grounded properly to protect against fatal
injury to personnel. Lugs included in J-Box.
· To protect against fatal injury to personnel, refer to NEC, CSA and local
utility regulations and any applicable local codes.

· Provide proper safety guards for personnel against possible failure of
motor-mounted brake, particularly on applications involving overhauling loads.
· The repair of Explosion Proof and VHS motors must be made by a UL
certified/authorized EASA service center that is certified by UL, CSA or other
appropriate agency. Failure to comply will violate hazardous duty
certification in accordance with NFPA70 NEC article 500 hazardous location of
electric motors.
· To find a UL shop visit the EASA website at www.easa.com
Storage
· For motors that will not be placed in service within six months of shipment
date. · Locate the motor indoors in a dry area (even temperature above -20°C),
without sunlight, well-
vented, and free of dust or corrosive gas. Store motor off the floor on rubber
mats, if possible. The motor should not be stored near heat or cold source
(i.e. boiler/freezer). Motor should be stored in upright position. · Measure
and record the resistance of the winding insulation every 30 days of storage.
· The storage area should have less than 60% humidity and be free of shock or
vibration. Vibration not to exceed 2 mils max. · Treat unpainted flanges,
shafts and fittings with a rust inhibitor. If motor is supplied with space
heaters, apply appropriate power to the space heater (½ voltage). · The shaft
should be rotated 15 revolutions stopping at a different position every month
to maintain proper distribution of grease in the bearing cavity. · Lubricate
open type bearings every six months.
Removal From Storage
· Remove all packing material. · Measure and record the winding insulation
resistance at the time of removal from storage. The
insulation resistance must not be less than 50% from the initial reading
recorded when the motor was placed into storage. A decrease in resistance
indicates moisture in the windings and necessitates electrical or mechanical
drying before the motor can be placed into service. · Regrease the bearings.

Handling
· Use correct material handling equipment to avoid injury. Use caution when
removing the motor from its packaging. Sharp corners may exist on motor shaft,
motor key, sheet metal and other surfaces.
· Before lifting the motor ensure all eyebolts are properly tightened and the
shoulders are in contact with the base.
· Eyebolts provided on the frame are designed for lifting the machine only. Do
not use these eyebolts for lifting the motor with coupled equipment such as
bases, pulleys, pumps, reducers, etc.
Location
· ODP motors are intended for use indoors where atmosphere is relatively
clean, dry, corrosive free & well-vented.
· Totally enclosed motors may be installed where dirt, moisture, chemicals
and/or dust are present in an outdoor location.
· Explosion proof motors are intended for use in hazardous areas, NEC, article
500 classified by Underwriters Laboratories, National Electrical Code,
Canadian Standards Association, and IEC79 (EN50014 & EN50018).
· Mill and chemical duty TEFC motors are designed for installation in high
corrosion or excessive moisture, salty atmosphere and extremely hostile
content in the environment.
· Standard TEFC motors are suitable for use in ambient temperatures between
-20°C to -40°C with low temperature grease to + 40°C and at elevations at or
below 1000 meters (3300 ft ASL). For temperatures higher or lower, please
contact WorldWide Electric.

Mounting
· Make certain that the underside of the motor feet and/ TABLE #1: TIGHTENING TORQUE
or the flange is clean and free of dirt. It is imperative FOR THE SECURING BOLTS
that the motor be level. Remove any masking materials
or any rust inhibitive coating from the mounting
surface and shaft.
Bolt Size
Recommended Torque
· All ball bearing motors, frame up to and including NEMA 326T, can be mounted in all positions shown in NEMA MG1-4.03, provided that the surface is stable and solid and the drain holes are located properly. Roller bearings are standard on crusher duty 404T-586/7 frames.

· When using a direct coupling, align motor shaft to
driven shaft as accurately as possible. Although a flexible coupling is
designed to transmit power with some angular and parallel misalignment, this
will have an effect on the life of the bearings.
· The motor must be securely installed to a rigid foundation or mounting
surface to minimize vibration and maintain alignment between the motor and the
shaft load. Failure to do so will cause vibration, misalignment and/or bearing
damage. The mounting bolts must be carefully tightened to prevent changes in
alignment and possible damage to the motor or equipment. These values are for
medium
carbon steel bolts (identified by 3 radial lines 120° on the bolt head-ANSI
grade 5). For low carbon steel bolts (ANSI grade 2), use 50% of this torque
(see TABLE #1).
· Remove drain plugs from the end shield or frame on totally enclosed motors. It is critical that the motor be mounted with these at the lowest point of the frame. If the motor is to be mounted with the feet in any position except down, these must be relocated to the appropriate position. Contact WorldWide Electric for advice.
· The use of pulleys, sheaves, sprockets or gears on motor shafts is defined in NEMA MG1-14.07. The application of v-belt sheave dimension on AC motors is shown in MG1-14.41.
· The pitch diameter must not be less than indicated in TABLE #2 and the maximum sheave width must not exceed:
· A. (N-W) for narrow type (3V, 5V 8V) sheaves
· B. 2X (N-W)- ¼” for conventional type (A, B, C, D, E) sheaves
· C. N-W is the usable shaft length (IEC designation is dim. E)
· For sheaves ratios greater than 5:1 and center distances less than the diameter of the large sheaves, refer the application to the WorldWide Electric office.
· Mount the pulley or half coupling to the motor shaft using non-impact method. Do not hammer on the motor shaft as this will cause brinelling of the bearing, leading to premature failure of the motor.
· The motor is balanced using a half key; therefore the motor pulley or half coupling should also be balanced with a half key. After mounting the coupling or the belt and pulleys, a guard must be placed over all of the moving parts to protect against accidental contact or injury.
· Do not over tighten the belts as this will lead to an excessive overhung load on the motor bearings, causing a significant reduction in bearing life and premature failure.

· Make certain that there is adequate space around the motor for ventilation. If using a belt pulley, the ventilation opening at the rim of the pulley is essential for the motor’s cooling. All ventilation openings must not be obstructed, and any wall or divider should be mounted a minimum of 30 inches (762mm) away from the motor.
Power Supply
The wiring of the motor and controls as well as TABLE #2: RECOMMENDED the grounding and overload protection should MINIMUM PITCH DIAMETERS
be performed in accordance with National Electrical Code, CSA C22-100 (C.E.C.) and all local and utility regulations and safety standards. Installation should be done only by properly qualified personnel.

Electrical Connection
Connect the motor as shown on the connection diagram on the motor nameplate.
Be sure to identify the proper wiring diagram for the supply voltage of motor
you are installing. If you have difficulty determining the proper wiring
diagram for your motor, please contact WorldWide Electric for assistance. If
this motor is installed as part of a motor control drive system, connect and
protect the motor according to the control manufacturer’s diagram. The wiring,
fusing and grounding must comply with the National Electrical Code or IEC and
local codes.
NOTE: WIRE NUTS ARE AN APPROVED TERMINATION METHOD
Startup
· Disconnect the load when starting the motor, making sure the key is removed
from the shaft. Check direction of rotation. If rotation must be changed allow
the motor to stop completely. Interchange any two incoming power leads of a
three-phase motor to change the direction of the rotation. See wiring diagram.
· Note: If improper rotation direction is detrimental to the load, check the
rotation or `bump’ the motor prior to coupling the load to the motor shaft.
When the motor is coupled to the load and started, it should start quickly and
run smoothly. If not, stop the motor immediately and determine the cause.
Possible causes are: low voltage at the motor, motor connections are not
correct or the load is too heavy. Check the motor current after a few minutes
of operation and compare the measured current with the nameplate rating.
· Motor with a service factor greater than 1.0 S.F. can be operated
continuously with the current not exceeding the nameplate value multiplied by
the service factor.
· Example: 18.1 amps x 1.15 S.F. = 20.825 full load amps.
· When using AC motors with frequency inverters, be certain that the motor’s
maximum speed rating is not exceeded.
· Pay special attention to the temperature reading on the motor, the outside
temperature or skin temperature of the motor, as well as monitoring, and
measure the inside temperature of the motor. Note: the bearing temperature
should not exceed 60°C. Surface temperature may exceed 90°C (194°F)” WARNING:
Do not touch the exterior of an operating motor. The motor may be hot enough
to be painful or cause injury.

Installation And Maintenance Manual For Polyphase AC Induction Motors | Current as of February 2024 Copyright 2024© WorldWide Electric Corporation | Document No: IOM-Polyphase-AC-Induction-Motors-02-01-2024
Testing
· If the motor has been in storage for a long period of time or has been
subjected to adverse moisture or extremely dusty/dirty conditions, it is best
to check the insulation resistance of the stator windings with a megohmmeter.
Depending on the length and conditions of storage it may be necessary to
regrease or change out oxide bearings. If resistance is lower than 1 megohm,
the windings should be dried in one of the following manners: · Bake in oven
at temperature below 194°F until the insulation resistance becomes constant
for a minimum of 30 minutes. Constantly monitor the conditions. · With the
rotor locked, apply low voltage (approximately 10% nameplate voltage) and
gradually increase current through windings until temperature measured with
thermometer reaches 87°C (188°F). Do not exceed this temperature. Maintain
this temperature until the insulation resistance remains constant 30 minutes.
Maintenance
· When the motor is in operation, examine the motor at regular intervals
(about 500 hours). Make sure the ventilation openings are clear and
unobstructed.
· Check the condition of shaft seals and replace if necessary. · Check the
condition of connections and mounting and assembly bolts. · Check the bearing
condition by listening for any unusual noise, vibration measurement, bearing
temperature, inspection of spent grease or SPM bearing monitoring.
Lubrication (Open Bearings)
The motor should be running when greased. Safety notice: Over-greasing
bearings greatly increases bearing friction and can cause premature bearing
and/or motor failure. See (TABLE #3) for lubrication intervals and (TABLE #4)
for lubrication schedule in hours. Worldwide Electric motors have SKF
bearings. The L10 life of the bearings subjected to routine maintenance is as
follows: (a) belt drive applications 50,000 hours (b) direct coupled
applications 100,000 hours. Do not mix greases unless compatibility has been
checked and verified.
Vibration Levels
Note: acceptable vibration levels at no load condition. · NEMA MG1-7 · 2-6
