Installation Instructions
Section A: Mounting the Motor Clutch Module
(10 Module)
1. Examine the clutch adapter. Note that there
are gaps between the housing fins on roughly
half of the circumference of the unit. Mount
the clutch adapter with the open gaps down.
This will keep contaminants from falling into
the unit. There are four screws and washers.
These will be bolted through the adapter onto
the four holes in the face of the motor (See
Figure 1).
3. Slide the rotor onto the motor shaft. (See
Figure 3) Make sure the rotor hub slides
easily onto the shaft. If the fit is too tight,
polish the shaft with emery paper so the hub
will slide on easily. Do not use a hammer or
force the rotor hub onto the shaft. Slide the
rotor back off the shaft.
Figure 1
2. Look at the back side of the rotor and note
there are cardboard spacer buttons as
depicted in figure 2.
Figure 2
Figure 3
4. Insert key onto the shaft. Prick punch the
motor shaft keyway at the end of the key to
prevent the key from sliding out. Slide the
rotor onto the motor shaft until it bottoms
against the field.
5. Using an Allen Wrench securely tighten the
two setscrews in the rotor hub. (See Figure 4)
When the motor is turned on, the spacer buttons will quickly wear away and provide the
proper gap between the field and rotor. The
setscrews are accessible from the front of the
rotor on sizes 100, 180, 210, and from behind
the rotor on size 50 units.
Figure 4

Section B: Bolting Two Modules Together
The brake module (20) and/or output clutch
module (40) may be assembled to the mounted
motor clutch module (10) or the input clutch (30).
1. Position the modules so that, in the usual
horizontal position, the ventilation holes are
down to prevent foreign matter from falling
into the units.
2. Bolt the modules together with the long hex
head bolts that are provided, see figure 5.
Mating pilot diameters assure proper alignment between module assemblies.
3. Proceed to Section C
Figure 6
Figure 5
Section C: Adjusting Airgap
For new installations it is necessary to adjust the
airgap between the friction faces of the clutch
and/or brake.
To set the airgap for an Electro-Module (EM) you
will need to access the armatures. On an EM
there are gaps between the fins on the housing
on 1/2 of the unit circumference. When looking
through this gap, you will see the fan on the
clutch rotor. In that fan there is a 1/2 x 1 inch
window. It is possible to look inside the unit and
see the armatures by looking through this window. When looking through this window you will
be looking between the two armatures of a
clutch/brake unit as shown in figures 6 and 7.
Figure 7
If the armature for either the clutch or the brake
is too far away from its mating friction surface, it
is possible to move this back into adjustment
using a flat blade screwdriver between the two
armatures. See figure 8.
Figure 8
Warner Electric • 800-825-9050 P-213 • 819-0303
5
This is a three step process.
C-face mounting
If this boss extends
beyond the C-face
surface use the
spacer.
Do not use spacer
if boss is below the
C-face surface.
1. Simply slide the screwdriver through the
window and press the armature toward its mating friction surface.
2. Rotate the output of the unit. The rotor and the
window should stay in place when you do this.
Only the armatures will move. Rotating the
rotor will move the window.
3. Repeat steps 1 & 2 to ensure that the airgap
between armature and its mating friction surface is about 1/32” and that the armature is
kept square. (If the armature is cocked, it may
engage on one rim, giving the appearance of
engagement but failing to provide full torque.)
3. When using the EM-180-20 a possible interference may exist between the splined armature hub and some motors. (See Figure 10) A
spacer ring is provided with the EM-180
mounting accessory to provide the necessary
running clearance.
Section D: Mounting the Brake to a Motor
The brake module (20) can be mounted directly
to a motor.
1. Insert a key in the motor shaft keyway. Prick
punch the end of the (EM-50 and EM-100)
motor shaft keyway to prevent the key from
sliding out.
2. A set collar is provided in the EM-180 and
EM-210 mounting accessory to prevent the
key from sliding out. Slide the set collar up
against the motor bearing and tighten the
setscrew securely. (Figure 9)
Figure 10
Place the spacer ring between the brake
module housing and the C-face of the motor
when bolting the two units together.
4. Align the motor shaft and key with the mating
shaft hole and key slot in the brake module.
5. Secure brake module to the motor C-face with
the four (4) long 3/8-inch hex head capscrews.
Section E: Installing the Motor Mount (M)
A Motor Mount (M) can be installed to the brake
or output clutch module to provide a foot mounting for the complete assembly of module and
motor.
1. Remove the two (2) long hex head bolts from
the side of the module toward the ventilation
holes.
Warner Electric • 800-825-9050 P-213 • 819-0303

2. Mount the module on the Motor Mount so that
the base of the Motor Mount is underneath
the modules and motor. (See Figure 11) A pilot
diameter on the module mates with a pilot
diameter on the Motor Mount.
Figure 9
Figure 11
3. Secure the Motor Mount in place with two (2)
longer mounting bolts and the two shorter
bolts all provided in the kit.
Section F: Installing the Base Mount
Section G: Mounting to a Reducer
The output side of a brake (20) or output clutch
(40) module may be mounted directly to a reducer.
1. Align the output shaft and key of the modules
with the corresponding shaft hole and keyway
of the reducer. Slide the assembly together,
matching the pilot diameter on the module with
a pilot diameter on the reducer. (Figure 13)
Modules 20-30 and 30-40 can be base-mounted.
1. Mount the modules so that the base is located
below the ventilation holes. A pilot diameter
on the end of each module mates with pilot
diameters on the base.
2. Secure the base to the modules with the four
(4) bolts provided. (Figure 12)
Figure 12
Figure 13
2. Bolt the module to the reducer flange. The
four (4) bolts required (3/8 - 16 UNC-2A) are
normally furnished with the reducer.
Section H: Electrical Connections
The conduit connection hole in the motor clutch
module (10), brake (20), and input clutch (30) are
threaded for standard conduit connectors. The
wiring diagram, included with each Warner Electric
control shows the proper electrical connections
that must be made. (Control Service Manual P-239
includes complete information on all standard
control power supplies.)
For clutch/brake combinations, connect the red
wire from one module and the black wire from the
other module to the same terminal of the DC supply. With most basic Warner Electric controls, one
terminal is normally used for two connections –
one from the brake and one from the clutch.
For wiring of clutches, brakes, and clutch/brake
combinations consult manual P-239 for the wiring
diagram of the control being used. These
clutch/brakes are not polarity sensitive.

Section I: Burnishing
Intimate metal to metal contact is essential
between the armature and the metal rings (poles)
of the magnet or rotor. Warner Electric clutches
and brakes leave the factory with the friction
material slightly undercut to assure good initial
contact.
Normally, the desired wearing-in process occurs
naturally as the surfaces slip upon engagement.
The time for wear-in, which is necessary to
obtain the ultimate torque of the unit, will vary
depending on speed, load, and duty cycle.
If maximum torque is required immediately after
installation, the unit should be burnished by slipping the friction surfaces together at reduced
voltage. It is recommended that the burnishing
be done right on the application, if at all possible.
Burnishing at high speed will result in a smoother
wear-in pattern and reduce the time for burnishing. The voltage should be set at approximately
30% or 40% of the rated value.
The unit should be cycled on and off to allow
sufficient time between slip cycles to prevent
overheating.
When a Warner Electric brake or clutch is
properly assembled and installed, no further
servicing, lubrication, or maintenance should
be required throughout the life of the unit.
Troubleshooting
If an Electro-Module fails to engage, there are
several possible causes. These can be broken
down into two sub-headings: Electrical and
Mechanical.
A. Visually inspect to ensure that the lead wires
are not split or cut.
B. Using a voltmeter confirms that DC voltage is
reaching the lead wires when it should be
and that the coil resistance is correct.
Mechanical - A likely mechanical cause for a
clutch or brake not engaging when DC power is
applied is that the airgap between the friction
faces is too large. When power is applied to an
Electro-magnetic clutch/brake, the unit magnetically clamps the friction faces together. An airgap that is too large can keep the unit from
clamping together. If the airgap is too small the
faces will rub all of the time.
To adjust the airgap, see Section C on page 5.
Maintenance
As with any friction-type device, some initial
concern should be given to wear rate, as minor
adjustments in actuation time can sometimes
extend the life of the unit.
For clutch modules, the control potentiometer
should be set high to reduce the actuation time.
For brakes, the setting can be reduced to
extend the braking time and thereby extend the
life. Once the best actuation time has been
established, precautions should be taken to prevent machine operators, or other personnel not
familiar with wear characteristics, from changing
the potentiometer setting arbitrarily for affecting
minor operating changes.
Electrical - If a clutch or brake or clutch/brake
will not engage, review the wiring, switching and
connections.

Wear Pattern
Torque Loss
Wear grooves appear on the friction surfaces.
This is a normal wear condition, and does not
impair functioning of the unit. Never machine
the friction surfaces to remove grooves or score
marks resulting from normal wear.
Heat
Excessive heat and high operating temperatures
are causes of rapid wear. Units, therefore,
should be ventilated as efficiently as possible,
especially if the application requires fast,
repetitive cycle operation.
Foreign Materials
If units are used on machinery where fine,
abrasive dust, chips or grit are dispelled into
the atmosphere, a screen over the ventilation
holes may be necessary.
Where units are used near gear boxes or
transmissions requiring frequent lubrication,
means should be provided to protect the
friction surfaces from oil and grease to prevent
serious loss of torque.
Oil and grease accidentally reaching the friction
surfaces may be removed by wiping with a rag
dampened with a suitable cleaner, which leaves
no residue. In performing this operation, do
not drench the friction material. If the friction
materials have been saturated with oil or grease,
no amount of cleaning will be completely effective. Once such a unit has been placed back in
service, heat will cause the oil to boil to the
surface, resulting in further torque loss.
If a brake or clutch module slips or loses torque
completely, the initial check should be the input
voltage to the magnet or field as follows:
90-Volt Series: Connect a DC voltmeter with a
range of 0-100 or more directly across the magnet or field terminals. With the power on and the
potentiometer turned up, a normal reading is 90
volts, although 85 to 95 is satisfactory. The
reading should drop as the potentiometer control is adjusted counter-clockwise.
24 Volt Series: Use a DC voltmeter of approximately 0-40 volt range. A normal reading is from
23 to 25 volts.
6-Volt Series: Use a DC voltmeter of approximately 0-15 volt range. A normal reading is from
5.5 to 6.5 volts depending on the power supply.
The above checks normally are sufficient.
Further checks may be made as follows: a low
range ammeter, when connected in series with
one magnet lead, will indicate amperes as
shown in chart on page 8. These readings are
with the power on and the potentiometer control
in the maximum position.
Ohmmeter checks should be made with the
power off and the circuit open (to be certain,
disconnect one lead to the magnet). A very high
or infinite resistance reading would indicate an
open coil.
If the above checks indicate that the proper
voltage and current is being supplied to the coil
mechanical parts should be checked to assure
that they are in good operating condition and
properly installed.

Electro-Modules are individual clutch or brake
units which are assembled together to comprise
a clutch, a brake or a clutch/brake combination.
Electro-Modules are designed for use with Cface motors and reducers. Some versions can
be base mounted as well.
The 10 Motor Clutch Module is designed to
mount on the face of the NEMA C-Face motor.
The rotor assembly has a hollow bore and is
mounted onto the shaft of the motor. The 10
Module cannot be used alone, it must be used
with either the 40 Module to create a clutch
combination or a 20 Module to create a

The 20 Brake Module is designed to mount on
the face of the NEMA C-face motor or in
combination with other modules. The 20 can be
used alone when mounted on the output of a
motor. In this mode it is a brake only. When
combined with the 10 Module, it becomes a
clutch/brake for mounting on a motor shaft.
When combined with a 30 Module it becomes a
clutch/brake for base mounting.
The 30 Input Clutch Module is designed for
applications where the unit is coupled to the
motor or where sprocket or pulley is mounted
on the input shaft of the 30 Clutch module. The
30 Module cannot be used alone. It can be used
NEMA Frame Standards
with the 40 Module to create a clutch
combination or it can be used with a 20 Brake
Module to create a clutch/brake combination.
An optional base is commonly used with these
combinations to provide a foot mounting capa-
bility.
The 40 Output Module is used with either the 10
or the 30 Modules. It cannot be used alone.
When combined with a 10 Module or the 30
Module it completes a clutch combination.
