MAINTENANCE INSTRUCTIONS
FOR THREE PHASE
INDUCTION MOTORS

Frames 143T - 449TZ

RECEIVING

1. Check nameplate data.

2. Check whether any damage has occurred during transportation.

3. After removal of shaft clamp, turn shaft by hand to check that it turns freely.

4. If motor is to be reshipped (alone or installed to anotherpiece of equipment)the shaft must again
be clamped to prevent axial movement.

Note: Remove the bearing clamp before turning the shaft on 284T-449TZ frame motors.

WARNING
THE FOLLOWING SAFETY PRECAUTIONS MUST BE OBSERVED:

1. Electric rotating machinery and high voltage can cause serious or fatal injuryif improperly

installed, operated or maintained. Responsible personnel should be familiarized with
NEMA MG-1; Safety Standards for Construction and Guide Selection. Installation and Use of
Electric Motors and Generators; National Electric Code and all local safety requirements.

2. Whenservicing, all power sources to the motor and to the accessorydevicesshould be
de-energized and disconnected and all rotating parts should be at standstill.

3. Lifting means, when supplied, are intendedfor lifting the motor only. When two lifting
devices are supplied with the motor a dual chain must be used.

4. Suitable protection must be used when working near machinery with high noise levels.

5. Safeguard or protective devices must not be by-passed or rendered inoperative.

6. The frame of this machine must be grounded in accordance with the National Electric Code and
applicable local codes.

7. A suitable enclosure should be provided to prevent access to the motor by other than

authorized personnel. Extra caution should be observed around motors that are
automatically or have automatic re-setting relays as they may restart unexpectedly.

8. Shaft key must be fully captive or removed before motor is started.

9. Provide proper safeguards for personnel against possible failure of motor-mounted brake,
particularly on applications involving overhauling loads.

10.Explosion proof motors are constructed to comply with the label service procedure manual, repair
of these motors must be made by or U/L listed service
center in order to maintain U/L listing.

LOCATION

1. Drip-proof motors are intended for use where atmosphere is relatively clean, dry, well
ventilated and non-corrosive.

2. Totallyenclosed motors maybeinstalled where dirt, moisture, or dustare present and in outdoor
locations.

3. Explosion-proof motors are built for use in hazardous locations as indicated by
Underwriters’ label on the motor.

4. Chemical duty enclosed motors aredesigned for installation in highcorrosion or excessive
moisture locations.

Note: in all cases, no surrounding structure should obstruct normal flow or
ventilating air through or over the motor.

MOUNTING

1. Mount motor securely on a firm, flat base. All ball bearing normal thrust motors up to and
including 256T frame size may be side-wall or ceiling mounted; all others check nearest
TECO-Westinghouse office for mounting recommendations.

2. Align motoraccurately, using a flexiblecoupling if possible.For drive recommendations,

consult with drive or equipment manufacturer, or TECO-Westinghouse.

3. Mounting bolts must be carefully tightened to prevent changes in alignment and possible

damageto the equipment. The recommended tighteningtorque’s for medium carbon steel bolts,
identified by three radial lines at 120 degrees on the head, are:

POWER SUPPLY & CONNECTIONS

1. Wiringof motor and control, overload protection and grounding should be in accordance with
National Electrical Code and all local safety requirements.

2. Nameplate voltage and frequency should agree with power supply. Motor will operate
satisfactorily on line voltage within ±10% of nameplatevoltage; or frequency with ±5% and
with a combined variation not to exceed ±10%. 230-volt motorscan be used on 208-volt
networksystems, but with slightly modified performance characteristics as shown on the
nameplate.

3. Dual voltage and single voltage motors can be connected for the desired voltage by
following connection diagram shown on the nameplate or inside of the conduit box.

4. All Explosion Proof motorshave Temperature Limiting Devices in the motor enclosure to
preventexcessive external surface temperature of the motor in accordance with U/L
standards. Terminals of thermal protectors (P1 & P2) should be connected to the motor
control equipment, according to the connection diagram inside of the conduit box.

5. Standard connection diagram for three phase, not thermally protected, dual rotation motors

are shown in diagrams A through E. (Note: To change rotation, Interchange any two line

leads)

*Important: For Part Winding Start, M2 contactor should be closed within two (2) seconds

after M1 contactor is closed.
Only 4 pole and above (e.g., 6P, 8P...) motors are satisfactory for Part WindingStart
at low voltage.

START UP

1. Disconnect load and start motor. Check direction of rotation. If rotation must be changed,
ALLOW THE MOTOR TO STOP COMPLETLEY. Interchange any two leads of a three-phase
motor.

2. Connect load. The motor should start quickly and run smoothly. If no, shut power off at once.
Recheck the assembly including all connections before restarting.

3. If excessive vibration is noted, check for loose mounting boltstoo flexible motorsupport
structure or transmitted vibration from adjacent machinery. Periodic vibration checks should
be made; foundations often settle.

4. Operate under load for short period of time and check operating current against nameplate.

TESTING

If themotor has beenin storagefor an extensiveperiodor has beensubjected to adversemoisture
conditions, it is bestto check the insulation resistance of the stator winding with a megometer.
Depending on the length and conditions of storageit may be necessary to regrease or change
rusted bearings.
If the resistance is lower than one megohm the windingsshould be dried in one of the following two
ways:

1. Bake in ovenat temperatures not exceeding 194°F until insulation resistancebecomes
constant.

2. With rotorlocked, apply low voltage and graduallyincrease the current through windings until
temperature measured with a thermometer reaches 194°F. Do not exceed this temperature.

INSPECTION

Inspect motor at regular intervals. Keep motor clean and ventilation openings clear.

LUBRICATION

1. Frame 143T-256T: Double shielded and pre-lubricated ball-bearing motors without grease
fittings and don’t need re-lubrication, except on MAX-E1®and MAX-E2®products which
have re-greasable features.

2. Frames 280TS, 320-449TZ(TS): Motors having grease fittings and grease discharge

devices at brackets. Motors are shipped with grease for initial running. It is necessary to
re-lubricate anti-friction bearingmotors periodically, depending on size and type of service. See
Table 2 to provide maximum bearing life. Excessive or too frequent lubrication may damage
the motor.

Note:

A. Standard conditions: 8 hours operation per day, normal or light loading, clear and 40°C

ambient conditions.

B. Severe conditions: 24-hour operation per day or light shock loading, vibration or in dirty or

dusty conditions.
C. Extreme conditions: With heavy shock loading or vibration or dusty conditions.
D. For double shielded bearings, abovedata (lubricationfrequency) meansthat the

bearing must be replaced.

3. Be sure fittings are clean and free from dirt. Using a low-pressure grease gun, pump in the
recommended grease until new grease appears at grease discharge hole.

4. Use the POLYUREA grease unless special grease is specified on the nameplate.

5. If re-lubrication is to be performed with the motor running, stay clear of rotating parts. After

re-greasing, allow the motor to run for ten to thirty minutes.
