WARNING!
THIS IS A HIGH PERFORMANCE PRODUCT CAPABLE OF DEVELOPING HIGH TORQUES AND SPEEDS.
IF YOU DO NOT INSTALL AND SERVICE THIS EQUIPMENT CORRECTLY,
YOU OR SOMEONE ELSE COULD GET HURT.
APPLICATION CHECKLIST
1. UPON RECEIPT
The motors and packaging are inspected before
shipment. Inspect your shipment for mechanical
damage that may have occurred in shipment.
Report any damage found to the freight carrier FIRST. Then
call POWERTEC for help in assessing the damage.
2. STORAGE
Store a motor in its original crate. Keep it in a clean, dry
location. Avoid hot, cold, or humid environments Grease may
settle in the bearings and harden over time. Rotate the shaft
monthly. Do not remove the Cosmoline rust prevention coating
from the shaft extensions until installation.
3. HANDLING
Use care in handling the motor. Avoid dropping it. Prevent
sudden impacts, especially on the shaft. The lifting lugs are
designed to lift ONLY the weight of the motor. DO NOT use the
lugs as the only means to lift with devices attached, such as
gearboxes.
4. ENVIRONMENT
Motor ratings are for an altitude of 3300 feet (1000 meters) or
less. You must de-rate the motor for higher altitudes.

DERATING FACTOR
ALTITUDE (X 1000) in feet above sea level
Motors are rated in accordance with NEMA Standard MG1-14.04.
For altitudes below sea level, use standard ratings.
For altitudes above 24,000 feet, consult the factory.
At a specified altitude: Multiply the motor HP by the de-rating factor.
ALTITUDE DERATING CHART


Install the motor in a clean, dry, well-ventilated area away from
heat sources. Air temperature should not exceed 40 °C (104°
Fahrenheit). For higher ambient temperatures, you must
derate the motor. See the graph below.

DERATING FACTOR
TEMPERATURE °C
Motors are rated in accordance with NEMA standard MG1-12.43.
For ambient temperatures below 40°C, use the 40°C rating.
For ambient temperatures below 0°C, consult the factory.
At a given ambient temperature: Multiply the motor HP by the derating factor.
AMBIENT TEMPERATURE DERATING CHART
De-rating is cumulative.
First de-rate for altitude; then de-rate for temperature.
5. GENERAL MECHANICAL INSPECTION
Before you install the motor, verify that the shaft is free to turn
and all mechanical parts are in their proper position. Turn the
shaft by hand to check for damage to the rotor. Remove the
Cosmoline coating on the shafts with a suitable solvent.

NOTE: If you have power leads shorted together in the
junction box, the motor shaft will not turn.
6. MOUNTING
You can mount the motor in any shaft position as long as you
keep radial and thrust loads within limits. Install foot-mounted
motors on a rigid foundation. You must use shims if the motor
mounting base is uneven. Do not cause unnecessary stress on
feet, frame and bearings by using poor mounting practices.

After installation, make sure that all bolts that hold the motor in
place are tight. See Mounting Bolt Torques on page 14.

7. ALIGNMENT
Alignment is very important for a motor that is directly coupled
to the load. The type of coupling device determines alignment
tolerances. Poor alignment allows vibration, which may result
in damage to couplings, bearings, rotor, or accessory devices.
8. BELTED APPLICATIONS
It is important that you use the correct sheave size and type.
You must also select the proper belts. See the Maximum Shaft
Radial Loading Table on page 14. When you size the sheaves
wrong, or tension the belts improperly, premature bearing or
shaft failure may occur. Mount the sheave as close as you can
to the motor housing. If you need help on sheave sizing, call
POWER

.

WHEN REMOVING PULLEYS FROM THE MOTOR SHAFT,
USE A PROPER PULLER. DO NOT PRY PULLEYS OFF BY
LEVERAGE AGAINST THE FRAME. YOU MAY DAMAGE THE
BEARINGS OR THE RETAINER PLATES BY PLACING STRESS
ON THE MOTOR SHAFT RELATIVE TO THE FRAME.
9. OPERATION
After you complete the mounting and alignment steps, you
may make electrical connections. You must follow the
connection diagrams exactly or the motor will not operate.

If turning the wrong way will damage the equipment, verify
motor direction before connecting the load. Monitor motor
current during the first operation of the motor. Compare it to
the motor nameplate value.

Check the motor cooling right after the start-up. Check it at
fifteen-minute intervals until the motor gets to normal
temperature (about four hours at full load).
10. MAINTENANCE
Make the first inspection within a few hours after placing the
motor in service, to catch problems caused by the installation.
Check the motor at least once per month after start-up.

Preventive maintenance means checking the motor often.
Make frequent checks for excess vibration, loose mounting
bolts and belts, odd noises (a steady hum is normal), and high
heat output.

FRAME OPERATING TEMPERATURES MAY BE
HIGH ENOUGH TO CAUSE BURNS! KEEP
ALL COMBUSTIBLE MATERIALS AWAY
FROM THE MOTOR!

SUMMARY OF WARRANTY
Brushless DC motors built by

are warranted against defects in materials and
workmanship for a period of two years from the date of
shipment from the factory. If a motor fails for any of these
reasons during this period of time, we will repair the motor or,
at our option, replace the motor. We reserve the right to
determine who will make repairs, and where the repairs will be
made. Claims for repairs under warranty must be submitted
within 30 calendar days from the first indication of the defect.
Unauthorized repairs are not covered by the warranty.
WARRANTY PROCEDURE
1.
When a problem with the motor is confirmed, write down the
serial number, model number, and job number of the motor. This
information is listed on the nameplate.
2.
Call your distributor, or our Service Department. at (803)
328-1888 or FAX the information to (803) 328-1870.
3.
Our service personnel will attempt to resolve the problem over
the phone. They may ask for information on the machine,
environment, and operation.
4.
If the problem cannot be resolved over the phone, we will
determine the best course of action to resolve the problem. This may
consist of sending parts, or returning the motor for repairs.
5.
If parts are to be sent, a purchase order will be required. A
Merchandise Return Authorization (MRA) number will be issued for
the parts. If the service is covered by warranty, credit for the parts will
be issued upon inspection of the old parts at the factory.
6.
Before the motor is returned to the factory for repair, an MRA
number must be issued by the service department.
7.
The MRA number must be displayed on the packaging of the
motor and on all paperwork. The paperwork must include a
description of the problem and return shipping instructions. Motors
returned without an MRA will not be acknowledged, and we are not
responsible for them.
8.
On repairs covered by warranty, there will be no charges for
materials and labor at the factory. The repaired or replacement motor
will be sent freight collect to the user.
9.
Repairs and replacements will be made in a timely manner. If
the user requires expedited service, there will be a charge for the
expedited service.

The warranty does not cover failures due to misapplication,
improper installation, accidental or intentional abuse, incorrect
electrical connections, and damages due to transportation or
handling. The warranty does not apply if any unauthorized alteration
has been done to the motor.
