• Adder is percent of Base List Price.
• Crusher Duty includes a special rotor design, increased locked rotor torque, increased breakdown torques and end turn bracing.
• Requires a review of load inertia and load curve for application.
• If application requires Roller Bearing and/or High Strength Steel Shaft, these adders must also be made.

Standard enclosed-frame products described in this catalog include drain holes in the low point of the brackets to prevent condensation buildup. Optional drain
and breather elements are available and will be installed by Nidec Motor Corporation for the following list prices. CORRO-DUTY
®
and severe-duty motors include
the rst option as standard. Drains/Breathers are not available on ODP/WPI/WPII motors.
Nidec Motor Corporation offers enhanced efciency products that feature design optimization and premium grade materials. We recognize your need for
increased motor performance is driven by the potentially signicant operational cost savings associated with enhanced motor efciency. Your power costs
savings are determined by a number of factors (depending on which payback method you select), including the cost of power and hours of operation. Because
not all motors run 24 hours a day, 7 days a week, we offer two pre-priced efciency options for TITAN
®
products.
Certain modications (high altitude, abnormal ambient temperature, 50HZ or other frequency, lower than standard temperature rise, multispeed products, copper
bar rotors, low noise designs, etc.) will cause motor performance to vary from stated values. Individual modications that have the tendency to impact motor
performance are noted in their description. Individual modications that have the tendency to impact motor performance are noted in their description. Should
any question exist, refer to your Nidec Motor Corporation Technical Representative.
A number of methods are available to evaluate the potential cost savings obtained by premium efciency motors. Nidec Motor Corporation sales engineers will
be happy to assist you and apply some of the more rigorous tests that include the time value of money at various yield rates. However, you may want to get a
general idea of the benets possible, and this can be accomplished by the simple payback method (shown below). This provides annual power cost savings
when the following items are known: Your cost / kilowatt hour of power, actual hours of operation and the full load efciency level of a standard vs. premium
efciency motor.

SIMPLE PAYBACK ANALYSIS EXAMPLE
RATING: 250HP - 1800 RPM - 460V
POWER COST: 5 cents per KW hour
OPERATION: Continuous duty - 8760 hours/year
PRODUCTS: Energy Efcient 95% @ F.L.
Premium Efcient 96.2% @ F.L.
ENERGY EFFICIENT
Annual power cost savings (Premium Efcient) = $1,072.63
S = .746 x 250 x .05 x 8760 [100/95 - 100/96.2]
S = 81687 [1.052632 – 1.039501]
• The difference in LIST price between the energy efcient (type J) and premium efcient (type JE) is $968.
Payback for this LIST price premium is less than a year.
• When you compare your actual net cost differences to the above illustrations this becomes a very attractive option.
• (3) See Base List Price Section for pricing.
• Open Dripproof (ODP): A machine in which the ventilating openings are so constructed that successful operation is not interfered with when drops of liquid or
solid particles strike or enter the enclosure at any angle from 0 to 15 degrees downward from the vertical (NEMA
®†
MG1). These motors with ventilating
openings which permit passage of external cooling air over and around the winding.
• Available on TITAN
®
Motors in 449-9600 Frame. For low voltage 449 Frame & smaller ODP motors, refer to the NEMA
®†
Horizontal Custom Motor
Catalog (PB202).
• Use ODP List Price plus above adder.
• Dripproof, Guarded: An Open Dripproof enclosure with all openings, including ventilated openings giving direct access to the live metal or rotating parts
(except smooth rotating surfaces) are limited in size by the structural parts or by screens, bafes, grills, expanding metal or other means to prevent accidental
contact with hazardous parts. Openings giving direct access to such live or rotating parts shall not permit the passage of a cylindrical rod of 0.75 inch diameter
(NEMA
®†
MG1).
• Available on TITAN
®
Motors in 449-9600 frame with the above adder; standard (no charge) on 8000 and 9600 Frames.
• Use ODP List Price plus above adder.
• Weather Protected I (WPI): An open machine with its ventilating passages so constructed as to minimize the entrance of rain, snow and airborne particles to
the electric part, and having its ventilated openings so constructed as to prevent the passage of a cylindrical rod 0.75 inch in diameter (NEMA
®†
MG1).
• Available on TITAN
®
Motors in 449-9600 frame with the above adder; standard (no charge) on 8000 and 9600 Frames.
• CORRO-DUTY
®
paint and coatings are available (but not in all cast-iron construction) for WPI motors. Should a customer require CORRO-DUTY
®
internal
and external protective treatments, add 3% for paint and coatings, and for cast-iron conduit box.
