A. Installing the Conduit Box
Install the conduit box on the magnet.
Instructions for this procedure can be found
with conduit box.
B. Mounting the Magnet
The brake magnet is mounted to a stationary
machine member by a flange. Extreme care
must be taken in selecting the location for the
mounting of the magnet. Proper positioning is
very important for the unit to function correctly.
1. A pilot diameter on the mounting surface
is essential to hold the magnet within the
required tolerances (see Figure 1).
3. Once the mounting surface has been prepared,
the magnet is bolted in place with capscrews and
lockwashers. (See Figure 2.)
Figure 2
4. After assembly, the magnet must be concentric
and square within the required tolerances listed
on the illustration drawing. (See Figure 3.)
Figure 3
C. Assembling the Armature and Hub
Assemble the armature to the armature hub with the
Figure 1
2. A machined pilot diameter is provided on the
magnet mounting flange (refer to illustration
drawings) to aid in the proper positioning of
the magnet.

autogap mounting accessory. Refer to Figure 4. The
hub is reversible. The side on which the armature is
mounted will depend on the direction in which the
taperlock bushing must enter.
The autogap assembly is a double spring device
which allows for automatic armature clearance and
adjustment for wear. The smaller or conical spring
pushes the armature from the magnet face, leaving a
gap of about 1/32-inch, while the straight spring
automatically follows up for wear. This combination
maintains maximum efficiency throughout the life of
the unit.

The assembly procedure for the autogap
accessory is as follows:
Step 1
Place the straight springs (white) over the
armature bosses on the back side of the
armature (Figure 5).
Figure 5
Step 2
Compress the heavy (red) spring on each drive pin
by sliding the detent spring towards the head of
the pin (Figure 6).
Step 3
Insert the assembled drive pins through the
armature (entering from segmented side), through
the straight (white) springs, and into the armature
®
hub. Note: Apply Grade "AA" Loctite
on the pin threads (Figure 7).
Figure 7
Step 4
Tighten the pins until the shoulders of the
pins are against the face of the hub. Since the
threads are class No. 3 fit, the pins may seem
to bind.
Sealant
The straight springs must not
get caught under the shoulders of the
drive pins.
Step 5
Check to see that the armature is completely
compressed against the face of the hub.

To set the autogap, slide the detent spring
retainers against the armature face. Note: This
position must not be disturbed during
completion of the assembly (Figure 8).
3. Place the face of the armature approximately
1/32-inch from the face of the magnet. Once
this gap is set, it will be automatically
maintained throughout the life of the unit.
(See Figure 9.)
Figure 8
D. Mounting the Armature Assembly
The armature and armature hub are mounted on
the shaft with a taperlock bushing. All parts must
be clean and free from burrs and chips before
assembling.
1. Place the bushing into the hub and insert the
key. The key is a side-to-side fit and should not
contact the top of the keyway.
2. Insert the locking setscrews into the bushing
and slide the assembly onto the shaft.
Figure 9
4. Securely fasten the armature assembly to the
shaft by alternately tightening each setscrew.
During the tightening process, the bushing
should be tapped lightly to make certain it
seats-in properly.

The motor brakes will mount on a NEMA "C" face
motors frame size 213C, 215C 254UC and
256UC.
A. Mounting the Splined Armature Hub
1. Insert the bushing into the splined armature
hub. Insert the two capscrews loosely into the
bushing.
2. Insert the key in the motor shaft.
3. Holding the hub so that the capscrew heads
are facing the NEMA motor, slide the hub on to
the motor shaft. (Figure 1)
B. Mounting the Adapter
1. Mount the adapter to the C-flange end bell of
the motor using capscrews and lockwashers.
The flat side of the O.D. of the adapter should
be mounted towards the bottom of the
motor. (Figure 2)
Figure 2
Figure 1
4. Position the armature hub in the location
specified by dimensions on the illustration
drawings.
5. Secure the hub in this position by alternately
tightening the two capscrews in the bushing.
6. After tightening the capscrews, recheck the
positioning dimension of the splined armature
hub. Reposition if necessary.
2. Mount the magnet to the adapter with
capscrews and lockwashers. Be sure both
surfaces are clean and free of burrs and
chips. Position the magnet so that the lead
wires are in position with the desired conduit
entrance. (Figure 3)

C. Assembling the Armature and Hub
These units contain spline drive armatures.
The armatures are shipped with a built-in spring
accessory. This device automatically maintains
a gap of about 1/32-inch between the armature
and magnet faces for the life of the unit.
These units are shipped with the armature,
splined armature adapter, and autogap already
assembled.
1. Slide the spline drive armature onto the splined
hub. The segmented side of the armature faces
toward the magnet. (Figure 4)
3. Bolt the cover to the adapter using
capscrews and lockwashers. (Figure 5)
Figure 5
Figure 4
2. Press on the splined armature adapter, and
slide the armature forward until it is in full
contact with the magnet face. Note: The
autogap detent ring in the splined adapter
grips the hub very tightly, and requires
considerable force to slide onto the hub.
When the armature is released, it will spring
back about 1/32-inch. This gap will be
automatically maintained for the life of
the unit.

Burnishing and Maintenance
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, or cycle duty.
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 burnishings 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
50% 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.
Maintenance
Wear Pattern: Wear grooves appear on the
armature and magnet surfaces. This is a normal
wear condition, and does not impair functioning
of the unit. Normally, the magnet and armature,
as a mating pair, will wear at the same rate. It is
the usual recommendation that both
components be replaced at the same time.
Remachining the face of a worn armature is not
recommended. If a replacement armature is to
be used with a used magnet, it is necessary to
remachine the worn magnet face. In refacing a
magnet: (1) machine only enough material to
clean up the complete face of the magnet; (2)
hold the face within .005" of parallel with the
mounting plate; and (3) undercut the molded
facing material .001" - .003" below the metal
poles.
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.
Warner Electric • 800-825-9050 P-208 • 819-0367
10
Foreign Materials: If units are used on
machinery where fine, abrasive dust, chips or grit
are dispelled into the atmosphere, shielding of
the brake may be necessary if maximum life is to
be obtained.
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.
with one magnet lead, will normally indicate
approximately .40 amperes for the 90 volt
units, 1.0 ampere for the 24 volt, and 3.5
amperes for the 6 volt series. 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). Average
resistance for the 90 volt series is 220 ohms;
for the 24 volt, 20 ohms; and for the 6 volt
series, 1.5 ohms. 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
magnet, mechanical parts should be checked
to assure that they are in good operating
condition and properly installed.
Torque Loss: If a brake or clutch slips or loses
torque completely, the initial check should be the
input voltage to the magnet as follows:
90-Volt Series: Connect a DC voltmeter with a
range of 0-100 or more directly across the
magnet 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 counterclockwise.
24-Volt Series: Use a DC voltmeter with a
range of 0-30 volts or more. A normal reading
is approximately 22-26 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.
The above checks normally are sufficient.
Further checks may be made as follows: a
low range ammeter, when connected in series

Warner Electric LLC warrants that it will repair or replace (whichever it deems advisable) any
product manufactured and sold by it which proves to be defective in material or workmanship
within a period of one (1) year from the date of original purchase for consumer, commercial or
industrial use.
This warranty extends only to the original purchaser and is not transferable or assignable without
Warner Electric LLC’s prior consent.
Warranty service can be obtained in the U.S.A. by returning any defective product, transportation
charges prepaid, to the appropriate Warner Electric LLC factory. Additional warranty information
may be obtained by writing the Customer Satisfaction Department, Warner Electric LLC, 449
Gardner Street, South Beloit, Illinois 61080, or by calling 815-389-3771.
A purchase receipt or other proof of original purchase will be required before warranty service is
rendered. If found defective under the terms of this warranty, repair or replacement will be made,
without charge, together with a refund for transportation costs. If found not to be defective, you will
be notified and, with your consent, the item will be repaired or replaced and returned to you at
your expense.
This warranty covers normal use and does not cover damage or defect which results from
alteration, accident, neglect, or improper installation, operation, or maintenance.
Some states do not allow limitation on how long an implied warranty lasts, so the above limitation
may not apply to you.
Warner Electric LLC’s obligation under this warranty is limited to the repair or replacement of the
defective product and in no event shall Warner Electric LLC be liable for consequential, indirect,
or incidental damages of any kind incurred by reason of the manufacture, sale or use of any
defective product. Warner Electric LLC neither assumes nor authorizes any other person to give
any other warranty or to assume any other obligation or liability on its behalf.
WITH RESPECT TO CONSUMER USE OF THE PRODUCT, ANY IMPLIED WARRANTIES WHICH
THE CONSUMER MAY HAVE ARE LIMITED IN DURATION TO ONE YEAR FROM THE DATE OF
ORIGINAL CONSUMER PURCHASE. WITH RESPECT TO COMMERCIAL AND INDUSTRIAL
USES OF THE PRODUCT, THE FOREGOING WARRANTY IS IN LIEU OF AND EXCLUDES ALL
OTHER WARRANTIES, WHETHER EXPRESSED OR IMPLIED BY OPERATION OF LAW OR
OTHERWISE, INCLUDING, BUT NOT LIMITED TO, ANY IMPLIED WARRANTIES OF
MERCHANTABILITY OR FITNESS.
Some states do not allow the exclusion or limitation of incidental or consequential damages, so the
above limitation or exclusion may not apply to you. This warranty gives you specific legal rights and
you may also have other rights which vary from state to state.
