GENERAL INFORMATION
GENERAL FEATURES
UNIQUE SQUARE LAMINATED STEEL FRAME
RPM AC motors are designed specifically for optimum inverter duty performance. From three generations of successful experience with laminated frame DC motors, RPM AC motors have been designed as square, laminated steel frame (L210 - L440 NEMA & DL132-DL280 IEC) to achieve maximum performance on inverter power. L180 and DL112 frames are available as cost effective aluminum frames).
RPM AC customer benefits:• Most cost effective solutions in the industry• Square frame designs allow larger horsepower ratings in
smaller frame sizes than NEMA cast iron motors without compromise in performance or life
• Stock availability from 1/3 - 1000 HP• Replace larger frame NEMA AC and DC motors easily• 1000:1 constant torque in vector mode is standard on
DPFV, TENV, TEBC and TEFC as shown in catalog. • Feet located on cast iron brackets provide more rigid,
vibration-resistant structure.• Rugged laminated steel frames(L180 frame is cost effective
finned aluminum construction)• Wide constant horsepower range - 4:1 to 12:1 available • High peak torque- 200% standard on enclosed motors;
300% to 400% available upon request• Low inertia for fast acceleration• Mount multiple accessories easily - encoders, brakes• Encoder provisions: machined opposite drive end bracket
and tapped shaft for addition of stub shaft are standard on DPFV, TENV and TEBC; a tapped shaft only is standard for TEFC for ease of mounting HS35 hollow shaft encoders.

Typical Applications
RPM AC motors have been successfully applied on a wide variety of applications. Because of the versatility to meet both wide constant torque and constant HP needs, optimum power matched solutions are available for the following:
Constant Torque:
Extruders, injection molding, conveyors, paper machines, crane and hoist. Includes web processing on printing press, metal coating, film and paper coating.
Cut-to -length applications on shears used in metals and paper corrugators
utilize the low inertia and mechanical ruggedness of laminated frame RPM AC
are examples where high peak torque to inertia for fast acceleration, and constant HP ranges of 4:1 up to 16:1 have been supplied. The ability to design very low base speeds and high response are standard with RPM AC.
High shock and Vibration: Stamping presses for automotive and metal stamping
take advantage of compact designs with feet on the brackets directly under the bearings. Includes high horsepower top drives for off shore oil rigs with the added demands of high humidity, salt spray and extreme ambient conditions.
Test stands:
Again, the fast response and compact mechanical features of RPM AC make it the choice solution for test stand applications. Depending on frame size, maximum speeds of 4000-9000 RPM are available.
Variable Torque Loads:
Because of the economic advantages and compactness of RPM AC motors, many customers have selected DPFV RPM AC for many variable torque applications, particularly for high horsepower requirements.

Introduction
BASIS OF RATINGS
The RPM AC motors in this catalog are designed specifically for use on IGBT voltage source controllers (PWM and six step VVI). Motor characteristics are optimized to reduce peak currents from the controller as well as to minimize motor losses. When the AC controller is properly adjusted, RPM AC motor performance will be in accordance with published rating data. The ratings in this catalog are based on a minimum PWM frequency of 4 khz for HP through 500, 2 khz for 600 HP and higher, and a minimum ratio of PWM frequency: fundamental frequency of 20:1.
Totally Enclosed Blower Cooled With Mounted Encoder
VOLTAGE SPIKE CAPABILITY
CORONA-FREE DESIGNS
(dv/dt and peak voltages)
RPM AC insulation systems have been tested extensively to insure successful operation on inverter waveshapes, includ-ing fast switching IGBTs. All motors are designed to with-stand high peak voltages caused by the combination of long lead lengths and steep voltage wavefronts, with
no corona formation
, for AC input voltages up to 575 volts RMS. Con-sult the control manufacturer for specific lead length recom-mendations.
All RPM AC motors have been designed to surpass the requirements of NEMA MG-1 1998, Part 31, Section 4 for definite purpose, inverter fed, polyphase motors for voltage spikes. All RPM AC motors for base voltage rating of 460 volts and below have been qualified by test to meet a mini-mum of 1600 volts peak, and a dV/dt in excess of 10,000 volts per microsecond. For voltages above 460 volts, includ-ing 575 volts, motors use an insulation system which is quali-fied by test to meet minimum peak voltages of 1850 volts and dV/dt in excess of 10,000 volts per microsecond rate of rise.
APPLICATION TOOLS
The RPMAC MOTOR WIZARD is a patented, revolutionary inverter duty motor selection program.
For custom motor requirements not found in the catalog, the WIZARD allows you to input exact values of altitude, ambient, base speed, wide constant HP speed ranges, enclosure, voltage, continuous torque and overload torque. The output includes: motor frame size, inverter kva, and typical motor amps. It allows evaluation of lower cost alternatives based on your needs. You can immediately print typical performance data curves, motor, conduit box and encoder typical dimensions.
A DUTY CYCLE CALCULATOR
is included in the RPM AC Motor Wizard to determine the motor frame size for load torques which vary cyclically over time.
The RPMAC MOTOR WIZARD CD can be ordered from Rockwell Automation, ordering number RAPS-517, through your Rockwell Automation contact. It can also be downloaded from the web at
www.reliance.com
. We encourage customer use of this powerful tool to aid in rapid selection of the exact motor for your application needs.

STANDARD MOTOR FEATURES
AGENCY LISTINGS AND CERTIFICATIONS –L180 through L440 Frame
ORDINARY LOCATIONS
UL file number E54825 CSA file number LR40567
All RPM AC motors are eligible for UL component listing and CSA Certification for Ordinary Locations for all enclosures. (Please note blower changes on certain TEBC Stock Ratings below for UL listing.)
It is necessary to request the CSA, UL or CE mark at the time of order entry – there is no extra charge for this when specified on the order.*
All RPM AC
IEC frame
motors include the CE mark as standard. The CE mark can be supplied on any motor, NEMA or IEC frame, but must be requested at time of order entry for NEMA frames, both stock and production.
IMPORTANT – Motors with modifications or accessories not approved by UL or CSA may not have the agency logo stamped on the nameplate.
CLASSIFIED AREAS – HAZARDOUS LOCATIONS
CSA file number LR46877
Class 1 Division 2 Certification Inverter Duty RPM AC
RPM AC motors have been tested and certified by CSA for operation on inverter power in areas classified as Class 1, Groups A, B, C and D, Division 2 for all TENV, TEBC, TEFC and DPFV enclosures. See Pricing and Modifications sections of catalog. Motor frame size will vary based on the NEC temperature code specified. Contact Rockwell Automation Sales Engineers representing DODGE and Reliance Electric brands of products for details.
NOTE:
Accessories supplied and mounted on the motor must be approved for Class 1, Division 1 or 2 and the same groups as main motor. This will limit the availability of some modifications. See available modifications in this catalog for further details.
Class 1 Division 1
RPM AC motors have been tested and approved by CSA for Class 1 Division 1 or 2 locations for Totally Enclosed Pipe In/ Pipe Out Ventilation - see Application section for details.
For UL listed explosion proof motors for inverter duty, see Variable Speed catalog.
ALTITUDE - AMBIENT
All motors in this catalog are based on 40 degrees C ambient, altitude of 3300 feet (1000 meters) above sea level at 1.0 service factor on inverter power. All motors are suitable for low ambient down to -25C as standard. Modifications can be selected for service factor, ambient and altitude as needed from the modification section.
TENV L180 Extruded Aluminum Frame
ADJUSTABLE SPEED CAPABILITY
All RPM AC motors in this catalog are rated
Vector Duty
, in that they are capable of 1000:1 constant torque below base speed. They are suitable for full load torque continuously at zero speed. RPM AC motors may be applied to inverters that are configured for vector control with encoder (flux regulated vector), sensor less vector, or scalar (volts per hertz operation). The constant torque speed range obtained is dependent on the control’s ability to properly regulate the motor flux. For example, continuous torque at zero speed may require a vector control with encoder feedback, depending on the specific performance requirements, including overloads and transient response.
*NOTE: On stock motors, the CSA mark for ordinary locations on all RPM AC motors in frames L180 - L440 (all enclosures), and UL logo in TEBC frames L360 - L440 will become standard and phased in after November 30, 2003.
Both the CSA mark and UL logo will also be standard on stock DPFV and TEFC models in frames RL210 - L440, and all TENV stock models.
The CSA mark and UL logo can be supplied on all production motors. The UL logo can be obtained on stock TEBC L180 - L320 by requesting the 56 frame blower package at no extra charge. Motor dimensions will change with 56 frame blower.

Introduction
OPTIMIZED FOUR & SIX POLE DESIGNS
The ratings in this catalog are based on the use of four pole laminations in frames L180 thru L400, and six pole in L440 frame, for adjustable frequency service. By designing the motor for rated voltage at the desired base speed, motor cur-rent and therefore controller size can be minimized. The base speed is obtained by adjusting the controller frequency as required. For example, with four poles, a base speed of 1750 RPM at 460 volts would require a 60 Hz nominal controller output frequency at 460 volts. A base speed of 850 RPM would require a 30 Hz frequency setting at 460 volts output. Using this approach, motors of the same horsepower with dif-ferent base speeds will have the
same nominal full load current
even though frame sizes will change. Motor designs are optimized for the exact base speed and not derated or overframed.
NOTE:
RPM AC motors are optimized for inverter power supplies. Contact Reliance Electric if by-pass mode (across-the-line) is required.
BALANCE
Standard - All RPM AC motors meet the dynamic balance limits of NEMA MG1 Part 7 for peak value of the unfiltered velocity in inches per second as shown below:
Standard Balance Limits
See Modification section for higher grade balance (Ultra Standard and Precision) and NEMA Standard in Table 1 in Modification Section.
BEARING - INSULATED
All RPM AC L440 frames include insulated opposite drive end bearing as standard.
BEARINGS - LUBRICATION
Standard - All RPM AC motors use deep-grooved anti-friction ball bearings.
Oversized ball bearings are standard on frames L180 through RL250 for both coupled and belted duty. Roller bearings are used for belted duty on frames UL280 through UL440.
These bearings and their internal clearances have been especially selected based on load carrying ability, thermal stresses and speed range consistent with ample bearing life. Double shielded bearings with oversize grease reservoirs that provide lifetime lubrication with no maintenance are standard on L180 and RL210-RL250 frames; bearings in frames L180, RL210 & RL250 are
not regreasable. Exclusive PLS lubrication incorporating open bearings with inner caps is standard on L280-L440 frames. See the Application Section for bearing life data.
Motors designed for higher than standard speeds may use special bearing construction other than stated above.
CONDUIT BOX (TERMINAL HOUSING)
Standard construction for frames L180 through L360 provides a gasketed, stamped steel box and cover.
Boxes can be rotated in 90 degree increments, and located in any quadrant as long as accessories are not in the same quadrant.
Standard construction for frames L400 and L440 are heavy gauge mill type conduit boxes
which can be mounted on either side or the top of the motor as long as not in the same quadrant as the blower. See the Modification Section for location and construction options.
Note:
L180 frame boxes can only be located on top of the motor.
For XT, Outdoor, or Paper Mill Duty, cast iron boxes are stan-dard in frames L180-L360. A large mill box is standard on L400 designs and all L440 frames.
Other conduit box loca-tions available on stock RL210-L440 and production
. See modification section.
CONNECTIONS
Motor power leads and thermostat leads are terminated in the conduit box and have sufficient length (approximately 6 inches) for connecting to the power leads.
DIRECTION OF ROTATION
All RPMAC motors are designed for bi-directional rotation. All motors are phase sequenced so that when voltages in an A-B-C phase sequence are applied to leads U/T1, V/T2, W/T3 clockwise shaft rotation facing the opposite drive end will occur.

ENCLOSURES
The basic price pages contain pricing for totally enclosed and drip-proof guarded force-ventilated motors. The IEC enclosure terminology is shown for reference only.
Drip proof Guarded Force Ventilated (IEC IP23/IC06) - ratings through 1000 HP (725kw) at 1750 RPM continuous duty (S1) are available.
Totally Enclosed Non-Ventilated (IEC IP44/IC410) - ratings available through 100 HP (75kw) continuous duty (S1), and 400 HP (300kw) 60 minute duty (S2 - 60 minutes)
Totally Enclosed Fan Cooled (IEC IC411) - ratings available through 250 HP (186kw) at 1750 RPM
Totally Enclosed Blower Cooled (IEC 416)- ratings available through 500 HP at 1750 RPM; IEC IC416 available up to 300kw at 1450 RPM.
The selection of the proper enclosure is vital to the successful safe operation of AC motors. The wrong enclosure can pose hazards to operating personnel and endanger other equip-ment. In addition, machine performance and life can be mate-rially reduced by using an enclosure inappropriate for the application. The customer must recognize the specific envi-ronmental conditions and specify the correct enclosure. Reli-ance Electric can provide application assistance but must depend on the customer to provide accurate information on the operating conditions.
The information in this section and the
Modification Section
should be studied thoroughly before specifying an enclosure.
As indicated in the
Introduction Section
, the basic RPM AC motor may be Drip-proof Guarded Force Ventilated, Drip-proof Guarded Separately Ventilated or totally enclosed. The minimum enclosure for RPM AC motors is Drip-proof Guarded (Force Ventilated) as defined by NEMA MG1-1.25.5 to prevent accidental exposure to live metal or rotating parts. The drip-proof construction permits successful operation when drops of liquid or solid particles strike or enter the enclosure at any angle from 0 to 15 degrees downward from the vertical. Certain applications may require the Splashproof Guarded (Force Ventilated) machine to permit successful operation when drops of liquid or solid particles strike or enter the enclosure at any angle not greater than 100 degrees downward from the vertical.
Both Drip-proof Guarded Force Ventilated and Splashproof Guarded Force Ventilated machines have a blower driven by a constant speed AC motor mounted on the end bracket to provide cooling independent of AC motor speed. A filter may be added to the blower when filterable contaminants are present in amounts not sufficient to rapidly clog the filter. A fil-ter is not recommended in extremely dusty, dirty locations.
Drip-Proof Guarded Force Ventilated (DPFV)
Motor cooling is provided by motor-mounted blower driven by an integrally mounted three-phase blower motor.
CAUTION:
The blower cooling system is designed for opti-mum cooling air flow. Blowers must not have any auxiliary duct work connected to the inlet shroud since reduction in air flow and motor overheating will occur.
Drip-Proof Guarded Separately Ventilated (DPSV)
For applications where cooling air is ducted to the motor from an external source provided by the customer.
For dusty, dirty environments, a totally enclosed machine is required to prevent the free exchange of air between the inside and outside of the enclosure but not sufficiently enclosed to be termed air-tight.
Totally Enclosed Air Over-Blower Cooled (TEBC)
RPM AC in-line blower cooled motors incorporate unique integral air ducts in the stator frame, external to the windings, to provide maximum cooling effectiveness. The integrally mounted, independently powered three-phase blowers result in low noise levels over wide speed ranges. TEAO-Piggyback blower is available as an option.
Totally Enclosed Non-Ventilated (TENV)
Does not require any external air flow for cooling.
Totally Enclosed Fan Cooled (TEFC)
Exterior surface cooled by external fan mounted on motor shaft, therefore making motor cooling dependent on motor speed.
XT Features
Provides protection against corrosive, moist and dirt laden environments as encountered in paper, chemi-cal and similar industries. Applicable to totally enclosed motors built in frames RL210 - L440 only. L180 available as washdown.
Outdoor Duty/Washdown Duty
Suitable for operation out-doors subject to direct weather conditions, or for frequent washdown by high pressure water or steam. Available in all frame sizes L180 - L440 on production basis.
Paper Mill Duty Features
Designed for operation at the wet end of a paper mill and in other harsh industrial environ-ments.
Totally Enclosed Pipe-Ventilated (TEPV) or Totally Enclosed Separately-Ventilated (TESV)
Motor is cooled by customer supplied air which is piped into the machine and ducted out of the machine by customer supplied ducts.
FINISH-PAINT
Standard finish is Reliance Electric blue-green (Munsell Color System 8.5BG3.57/2.0) high-grade modified epoxy, air dry enamel with non-toxic rust inhibitors.
GROUNDING
Motors powered from adjustable frequency controllers will have voltages induced on inactive components, such as the motor frame, as a result of capacitive coupling of the switched voltage wavefronts from the controllers. PROPER GROUND-ING OF THE MOTOR FRAME IS ESSENTIAL.
All RPM AC motors have a ground lead provided in the motor conduit box as standard for grounding, except L180 which has ground screw provisions inside the conduit box.

Introduction
INSULATION SYSTEM
The standard insulation system for RPM AC is thermally rated for NEMA Class H of 180
°
C. All components of the sys-tem have been carefully selected to be fully compatible with any IGBT voltage source type controller, whether it is PWM or VVI. Premium VPI insulation is standard on all RPM AC L440 frames.
MOUNTING
All RPM AC frames are suitable for floor, wall or ceiling mount and with shaft at any angle from horizontal to vertical.
OVERLOADS
Momentary Overloads - all RPM AC motors have been designed for an overload capability of 150% (for DPFV) and 200% (for TEBC, TENV, and TEFC) of the base speed full load torque for 1 minute at all speeds within the constant torque speed range.
TACHOMETER MOUNTING
All RPM AC motors have as a standard feature a machined opposite drive end bracket and tapped shaft provision for stub shaft for mounting an integral encoder. Mounting kits are available for selected encoders. The most cost effective encoder selection is a hollow shaft design and since it mounts on the stub shaft, no coupling or adapter is required. A tether arm mounts to the motor bracket.
For TEFC motors in RL210 - L400 frames, a fan cover with machined fit for accessory mounting is available as a modifi-cation, if brakes and/or coupled/bearingless encoders are required. A machined fan cover is standard on L180 frames. See Variable Speed catalog RAPS 692-1 for detail.
TEFC With Hollow Shaft HS35 Encoder
DPFV 1000HP 1750 RPM L4461 Frame
TEST - STANDARD
Each motor is given a full load test
on a PWM power supply, and a routine test in accordance with IEEE 112 as modified by Reliance Electric for inverter power. This provides customers with assurance that all motors meet design specifications. Routine test consists of:
Stator winding resistanceHi potential testNo load and full load ampsNo load and full load speed
See Modification section for price to supply certified routine test report price and other test options.
THERMAL PROTECTION
All RPM AC motors include three normally closed thermostats (1 per phase) connected in series, as standard. Leads are brought into the main conduit box as standard.

Introduction
RPM AC Inverter Duty Motors
Stock Model Number Cross Reference List - L Frames To RL Frames
In 2003, we redesigned the L210 and L250 frame motors to make them more price competitive and have faster manufacturing times - now four weeks for any non-stock model number shown. Ratings at 1750 & 1150 RPM are stocked as shown. We also extended our stock TEFC RPM AC 1000:1 constant torque product line up to 40 HP at 1750 RPM and 200 HP non-stock. This offers custom-ers a choice for applications that require traditional high performance, with compact mounting dimensions using a shaft driven fan instead of a motor mounted blower. Of course, TEBC and DPFV enclosures are still available and stocked as shown. These new frames, shown as RL210 and RL250 frames in this catalog, will replace the current L210 and L250 frames. The cross reference chart below is for your convenience when replacing the L210 and L250 frame designs.

MAXIMUM SAFE SPEEDS
The speeds shown are the maximum mechanically safe operating speeds for frames with standard construction, based on coupled duty only. These speeds must not be exceeded under any condition. Motor control must hold the maximum speed under any load condition including no load within the maximum safe speed. Controls whose design characteristics inherently prevent the AC motor from exceeding the motor maximum safe operating speed must prevent the motor from exceeding the max. safe speed if a single component should fail.

Introduction
Engineering Estimating Data (con’t)AIR SUPPLY
Drip-Proof Guarded Separately Ventilated (DPSV)For applications where cooling air is ducted to the motor from an external source provided by the customer.For dusty, dirty environments, a totally enclosed machine is required to prevent the free exchange of air between the inside and outside of the enclosure but not sufficiently enclosed to be termed air-tight.
Separately ventilated motors (DPSV, TEPV & TESV) must have the following volume of air to adequately cool the motor unless the nameplate specifies a different value. Cooling air temperature must not exceed the maximum ambient temperature indicated on the motor nameplate (Standard is 40° C). This data applies to all base speeds for the frame size shown:

CAUTION: The blower cooling system is designed for optimum cooling air
flow. Blowers must not have any auxiliary duct work connected to the inlet shroud since reduction in air flow and motor overheating will occur.
