Introduction
This training guide provides a step-by-step procedure for identifying the nomenclature forSEW products. An understanding of nomenclature is essential for several reasons:
To identify existing products in the field
To reduce miscommunications upon ordering
To help identify spare units in inventory
Goal
The goal of this manual is to familarize the reader with available options, and with the logicused to generate nomenclature. Wherever possible, graphics are included to illustrate
particular features or concepts.
Audience
This manual is essential for salesmen, distributors, purchasing agents, and anyone else
who specifies SEW products. Since it eliminates memorization, it is particularly useful for
the novice person who infrequently orders SEW products. It is also very useful for any
person who wants to know the particular features on the SEW products within his/her
plant.

Nomenclature
2 Overview and Rules
Nameplates
SEW identifies products and most options by either
a letter, a number, or a letter/number combination.
The sum of all letters and numbers is called theproducts model number, or nomenclature. It
appears on the stainless steel nameplate attached
to the gear reducer and/or motor.
SEW products contain either one or two
nameplates. An integral gearmotor consisting of a
gear reducer and an SEW integral motor has two
nameplates - one on the gear reducer, and one on
the motor, as shown in Figure 1.
A gearbox without a motor (such as a C-Face gearreducer) has only one nameplate, as shown in
Figure 2.

3Overview and Rules
Nomenclature
Figures 3 and 4 are pictures of both nameplates.The first line is the Type field, which displays thenomenclature described within this book.
The second line contains an SO#, or Sales Ordernumber. Even though the two nameplates havethe same SO#, the nomenclature on the reducer
nameplate differs from the nomenclature on themotor nameplate.
The Motornameplate does not contain
information about the gearbox. However, it doescontains all of the electrical data about the motor.Therefore, the motor nameplate is widely used
during installation.
The Reducer nameplate contains motornomenclature, but no motor data. However, it
contains all gearbox data. Thus, SEWrecommends using the reducer nameplate whenordering replacement parts, spares, etc.

4 Overview and Rules
Sequence and Fields
This section explains the proper sequence in which to
place the letters or numbers within the nomenclature.
Nomenclature begins at the output shaft of the gearreducer and ends at the motor.
To understand the logic, products are divided into fieldswith names. Figure 5 below is the diagram of agearmotor from Chapter 2. Notice that it has 13 fields.
The names of the fields are listed below the picture.

5Overview and Rules
Nomenclature
What is a field?
A field is a category that contains a list of options fromwhich to choose. Each option has either a letter,
multiple letters, or a combination of letters/numbersassigned to it.
For example, Field #1 represents the Gear Typecategory that has six options: Helical-Parallel (x2),theSnuggler, Helical-bevel, Helical-worm, and Hypoid.Each of these options has either one or two lettersassigned to it. The letter F denotes theSnuggler.
For theSnuggler, begin by aligning all 13 fields into arow. Next, place the letter, F, in Field #1, as shown
below.
To establish the entire nomenclature, fill in each fieldwith all required options, as shown in the following
example.
Note: Blank fields are acceptable. Refer to Rule 1 on
the next page.
When finished, add the letters and numbers together,eliminating all blanks, to obtain the following:

6 Overview and Rules
Rules
The following rules ensure that all options appear in the proper sequence.
Rule 1: Skip a field and leave it blank if none of its options are needed.
Mechanical Variable Speed(Select all that apply)
Rule 3: Place the letters in the order as they appear on the page.
In the fields that allow multiple options, place the letters in the order as they
appear on the page. The correct order is down and across the page, as
illustrated in Figure 6 below. When there are too many options to show on onepage, the field number contains a letter after it to indicate multiple pages. Forexample, the Mechanical Variable Speed field contains four pages, labeled 6a, 6b,
6c and 6d.
6a 6b
Rule 2: Choose only one option from each field, unless otherwise noted.
In most fields, it is physically impossible to combine more than one option within
the same field, such as a hollowshaft and a solid shaft. However, there are a fewfields where multiple options are possible, such as the Mechanical VariableSpeed (Field #6).
Multiple options are available when the field contains the words, Select all thatapply beneath it, as shown below.

7Overview and Rules
Nomenclature
Depending upon the type of gear reducerin Field #1, some options may not be
available. For example, with a type Rgearmotor shown in Figure 7, it is notpossible to receive a hollowshaft.
Therefore, in order for you to know whichgearbox accepts which option, the lowerright corner of the option block contains
letters, as shown in Figure 8.
As another example, notice that the TorqueArm option in Figure 9 contains the letters
S and K in the lower right corner. There-fore, this option is available for a type Sreducer (Helical-worm) and a type Kreducer (Helical-bevel).
However, neither an F nor an R appearin the lower right of the torque arm option.Thus, it is not available for a type F
(theSnuggler) or a type R (Helical-Parallel).
Rule 4: Select only the options that are available for your reducer.
A Hollowshaft + Key These letters correspond to the typesof reducers that accept the option.
This hollowshaft option, for example,does not have a letter R in the lowerright corner. Therefore, a hollowshaftis not available with a type R gearreducer.

NOTE: If the lower right corner is blank (no letters), then the
option is available on all gear reducer types.

8 Overview and Rules
Rule 5: Identify in which Chapter of this book to begin.
Each chapter contains different products, along with different fields and options.
It is important to know in which chapter of the book to begin. The title of each chapterappropriately identifies the products contained within it. However, the following stepsalso provide guidance, when performed in the proper order.
New Units:YES NO
Step 1: Is a gear reducer needed? See Chapter 2 Go to Step 2
Step 2: Is mechanical variable speed See Chapter 3 Go to Step 3 needed?
Step 3: Is an SEW motor needed? See Chapter 4
Existing Units:
The nameplate of an existing unitdisplays the nomenclature in theType field. Use the chart at right todetermine the proper chapter that
gives an explanation of the letters andnumbers in the nomenclature.
When the model begins with D, useall of the beginning letters whenmaking a selection from the chart. Forexample, if the model number reads
DFV132S4, use DFVin the chart, notD or DF. The correct answer isChapter 4, not Chapter 3.
An another example, suppose thenameplate of an SEW product says,
DF26BEFDT90L4. Since the unitbegins with DF, begin in Chapter 3.

Thermistors
(Variable Resistors)
Thermostats(Bi-metallic Switches)
Each of the three phases of the stator windingcontains a variable resistor (varistor). Its
resistance changes with heat and is mea-sured by a trip control, such as an SEW
Movidriveor ABBs CM-MSS (also availablefrom SEW).
A Movidrive measures the resistance of thevaristor. When it reaches 2.9 kilohms, the
Movidrive faults to protect the motor.
With a trip control device, a normally closedcontact on the device is placed in series withthe users motor holding circuit. When
excessive heat causes the resistance in anyvaristor to reach a set value, three things
occur in sequence: 1. The contact opens.2. The holding circuit disengages. 3. The
motor stops.
Each of the three phases of the stator
winding contains a thermostat, consisting ofa normally closed bi-metallic strip. All three
thermostats are placed in series with theholding circuit of the users motor starter.Excessive heat causes the bi-metallic strip
to expand, opening the circuit to stop themotor.
Class F or Class H available.

Flange/Shaft Combinations
There are a few versions of the flange/shaft combination that are available for a Varimot or Varigear.The nomenclature remains the same for all versions. For example, a flanged Varimot always has
the letters DF in Field #1 regardless if the Varimot mounts to an SEW gearbox, to a customers
machine, or to an IEC motor adapter. Since the model number is the same, the correct versionmust be specified when ordering. The shaft diameter and the orientation of the flange holes identify
the version type, as explained below.

61Mechanical Variable Speed w/o Gear Reducer
Nomenclature
Inch Version
Includes a inch-series shaft diameter and key. The shaft contains a centering hole, which is taperedbut not threaded, to aid with the removal of sprockets, couplings, etc. The inch version is onlyavailable on a flanged Varimot, not on a flanged Varigear. Depending upon the size of the
Varimot, either one, two, or three metric flanges are available - each containing a 45obolt pattern.To obtain the correct flange size, specify the BD dimension of the flange (outer diameter) whenordering.
IEC Version
Includes a metric shaft, metric key, and a flange with a 45obolt pattern. The center of the outputshaft contains a threaded hole with a tapered end. The taper acts as a centering device to assist
the removal of components from the shaft, while the threads provide support for a retaining boltwhen mounting components onto the shaft. Depending on the size of the unit, either one, two, or
three flange sizes are available. One of the flanges contains a hole pattern and diameter thatmatches the dimensions of a standard IEC motor. To obtain the correct flange size, specify theBD dimension of the flange (outer diameter) when ordering.
Gearbox Version
Includes a metric pinion shaft, a snapring, and a flange with a 90obolt pattern. Since the flangemates to an SEW gearbox, the flange contains an oil plug. The plug serves as either a breatherlocation or as an oil level indicator, depending upon the mounting position. To obtain the correct
flange size when ordering, specify the model number of the gearbox to which the unit attaches.
The gearbox version also contains an oil slinger on the output shaft. When the pinion gear rotates,
the gear teeth propel oil contaminates at a high velocity, which could cause seal damage or oilleakage. The slinger serves as a protective barrier between the seal and the oil.
If necessary, SEW can provide a pinion gear mounted onto the output shaft. However, in order to
ensure the correct gear when ordering, please specify the reducer model number and ratio to whichthe unit attaches.

TH Thermostats(Bi-metallic Switches)
Each of the three phases of the stator windingcontains a thermostat, consisting of a normally
closed bi-metallic strip. All three thermostatsare placed in series with the holding circuit ofthe users motor starter. Excessive heat
causes the bi-metallic strip to expand and openthe circuit to stop the motor.
Class F or Class H available.
TF
Thermistors
(Variable Resistors)
Each of the three phases of the statorwinding contains a variable resistor (varistor).
Its resistance changes with heat and ismeasured by a trip control, such as ABBs
CM-MSS (available from SEW).
A normally closed contact on the trip controldevice is placed in series with the usersmotor holding circuit. When excessive heat
causes the resistance in any varistor to reacha set value, three things occur in sequence:
1. The contact opens. 2. The holding circuitdisengages. 3. The motor stops.
