60 Series End-mount
Brake Instructions
Enclosed WPDT Housing
with Deep Drawn Cover
DESCRIPTION
These magnetic disc brakes mount directly onto NEMA 56C,
143TC, and 145TC frame motors, on the end opposite the
drive shaft. The brake is direct acting, electro-magnetically
released, and spring set. It uses rotating friction and station-
ary disc contact to supply positive braking action. It retains
quick release and setting capabilities at all times.
Model 6-60000-545 is designed to mount directly onto
C-face motors where a gasket between the brake and motor
will prevent liquid media from entering the brake.
Model 6-60000-535 is for TEFC motors or foot mount
applications. The hub seal prevents liquid media from
entering the brake through openings in the motor fan cover
or foot mounting bracket.
WARNING: Do not install or use these brakes in an
explosive atmosphere.

INSTALLATION
CAUTION: To preserve pre-alignment of rotating discs
for ease of installation, do not operate manual release or
energize brake coil before installation.
NOTE: The brakes are designed for horizontal mounting.
Modification is required for vertical mounting. Brakes that
are modified will have a prefix on the model number of VO
(Vertical Over) or VU (Vertical Under).
Mounting Hub on Motor Shaft
For Model 6-60000-545:
Refer to Figure 3.
1. Place rotating disc hub, with key, onto motor shaft with
part number facing away from motor. Measure from
motor face as shown.
2. Tighten both setscrews to 8 - 10 lb. ft. torque.
For Model 6-60000-535:
Refer to Figure 4.
1. Remove rubber v-ring from v-ring hub assembly.
2. Place v-ring hub assembly onto motor shaft, with part
number facing away from motor. Measure from motor
face as shown.
NOTE: If motor shaft keyway extends into v-ring
area, install a key long enough to engage v-ring hub
assembly and rotating disc hub. See step (3) before
tightening setscrews. Tighten both setscrews to 35
lb. in. torque.
3. Place “RTV” sealant in small amounts to fill crevices
only. Attention should be paid to the areas around and
between the v-ring hub assembly, reference the .040” x
45ochamfer, motor shaft, hub keyway and motor shaft
keyway. Use Dow Corning #739 RTV only; other types
may form acetic acid during curing if subjected to water
or high humidity. This will cause premature failure of
zinc plated parts.
CAUTION: If this procedure is bypassed, liquid
media may seep into the brake.
4. Replace v-ring onto v-ring hub assembly. Apply a small
amount of grease to the lip of the v-ring.
5. Place rotating disc hub with key onto motor shaft with
part number facing away from motor. Measure from
brake mounting face as shown. Tighten both setscrews
to 8 - 10 lb. ft. torque.

Placing Brake on Motor Shaft
1. Remove cover. Place gasket on the motor mounting face.
Position brake over hub on shaft, aligning hub splines
with rotating friction disc splines. Drain plug to face
down on horizontal models.
NOTE: For model 6-60000-535 a second gasket is
positioned between the bracket and adapter bracket.
If gasket does not make contact around the mounting
face completely (360o), remove gasket and place
RTV sealant around the mounting bolt holes to
approximately 1” dia. Use Dow Corning #739 RTV
only; other types may form acetic acid during curing
if subjected to water or high humidity. This will
cause premature failure of zinc plated parts.
If tapped holes in motor for mounting bolts are not
totally enclosed, place RTV sealant around threads
before bolting brake to motor. Use Dow Corning
#739 RTV only.
If water can accumulate in the cavity between the
v-ring hub assembly and fan guard or other unsealed
mounting face to the height of the v-ring seal, drill a
hole in the fan guard or other equipment so the water
drains out.
2. Tighten mounting bolts to 25 lb. ft. torque.
3. Connect coil leads as outlined under “Connection of Coil
Leads” and Fig. 3.
4. Let RTV #739 cure 24 hours before replacing cover.
5. Replace cover . Tighten cover screws to 5 lb. ft. torque.
Connection of Coil Leads
After securing the brake to the motor, connect coil leads for
proper voltage per wiring diagram (Fig. 5 shows dual voltage
coil). Incorrect connection can result in brake failure.
CAUTION: The voltage supplied to the coil must match
the voltage that the coils are connected for, or the coils
will burn out.
Single voltage coil:
Connect brake coil leads to any two line leads (single or three
phase) of same voltage and frequency as brake.
Dual voltage coil:
Connect leads 2 and 4 to any two motor line leads (single or
three phase) of same voltage as brake. Connect leads 1 and 3
as shown for voltage desired. Brake must be energized with
motor.
OPERATION
These brakes are spring set devices with an electrical
(magnet) release. They contain a rotating friction disc
that is driven by a hub mounted on the motor shaft. When
energized, the magnet compresses the torque springs,
removing the force pressing the stationary disc and friction
disc together. This permits free rotation of the shaft.
WARNING: Observe proper safety precautions in
applications where a brake failure would allow the load
to move in such a manner as to injure personnel.
KEEP PERSONNEL AWAY FROM LOAD AREAS.
If brake torque rating is higher than motor full-load torque
rating, use brake rating rather than motor rating when
selecting other drive components.
Take the following precautions when operating the brake:
1. Do not operate the brake at higher than nominal static
torque capacity.
2. For applications with high inertia-type loads or rapid
cycling, the thermal capacity of the brake must be
considered.
3. High start-stop rates may damage motor. Consult motor
manufacturer if high cycling rates are expected.
4. Be sure power supply conforms to electrical rating of
brake.
Manual Release
The brake is equipped with a manual release. Turn the release
knob clockwise to stop position to release the brake. The
brake will remain released until the release knob is turned
counterclockwise (approx. 65o) or until the brake coil is
energized, automatically resetting the brake.

MAINTENANCE
Caution: Before attempting to service or remove
any components, make certain that the power is
disconnected and that the load is completely
removed, secured or blocked to prevent injury or
property damage.
Wear Adjustment
Caution: Load to be removed or blocked. Brake may
be inoperative during this procedure.
Before air gap “A” reaches .100”, adjustment is
required. Any delay in adjusting the magnet air gap
will result in eventual loss of torque.
Refer to Figure 6.
1. Remove cover to expose square head wear adjusting
screws (15H) and expose magnet air gap “A.”
2. Measure air gap “A” using 3/8” to 1/2” wide feeler
gauge. (Measure at center of magnet.) Air gap
must be the same on both sides of magnet.
3. Turn two square head adjusting screws (15H) until
air gap “A” measures:
.045/.050 for 1 disc models
.050/.055 for 2 disc models
.060/.065 for 3 disc models
4. Replace cover, sealing washers and cover screws.
Tighten to 5 lb. ft. torque.
Torque Adjustment
Caution: Load to be removed or blocked. Brake may
be inoperative during this procedure.
The magnetic disc brake is factory set for rated static
torque. The brake can be adjusted to reduce torque
which increases stopping time. Do not attempt to adjust
brake for higher torque, as this will cause premature
coil burnout.
Refer to Figure 7.
1. To adjust, remove cover to expose torque locknuts
(15T), which are above torque springs (15S).
2. To increase stopping time and reduce torque, turn
both torque locknuts counterclockwise, increasing
spring length. Each full turn reduces torque 7% to
10% depending on the model.
NOTE: Maximum spring length is 1.2”. At
maximum length reduced torque will be:

Armature Plate Assembly Replacement
Caution: Load to be removed or blocked. Brake will be
inoperative during this procedure.
If you replace the magnet assembly, it may be necessary to
replace the armature plate assembly. If it is badly deformed,
it will be difficult to make the magnet quiet.
1. To replace, remove operator assembly (15) from
brake. See “Friction Disc Replacement Steps 1-3”
on page 6.
2. Remove nuts (15T), springs (15S), and carriage bolts
(15R). This will allow the armature plate assembly
(15E) to be removed from magnet bracket.
2. Reassemble new armature plate assembly to magnet
bracket (15C) using items (15R), (15S) and (15T).
Reassemble operator assembly to brake bracket. Set
magnet air gap “A” and set torque springs (15S) to
1” as shown in Fig. 6 and 7.
Pivot Stud Adjustment
Caution: Load to be removed or blocked. Brake will be
inoperative during this procedure.
This adjustment is made at the factory and may be required
when replacing the magnet assembly or the armature plate
assembly.
The purpose is to regulate the height of the armature plate so
that when the magnet is energized, the armature is parallel
with it. This is required so that the magnet will be quiet.
NOTE: Cover must be removed to make this adjustment.
1. To adjust: Hold nut (19) which is adjacent to washer
(18) and loosen the other nut (19) and remove it
from the stud.
2. Energize the magnet and turn remaining nut (19)
counterclockwise slowly until the magnet becomes
noisy. Turn magnet on and off several times until
you find the position where the magnet first becomes
quiet. At this point turn nut (19) 1/3 turn (two flats)
in a clockwise position. Hold nut in this position and
turn magnet on and off to make sure the magnet does
not become noisy.
3. Holding this nut in place, screw on other nut and
tighten it against the nut you are holding. Tighten
firmly.
4. Operate the manual release. If the release does not
operate properly, see “Manual Release Adjustment.”
Manual Release Adjustment
Caution: Load to be removed or blocked. Brake will be
inoperative during this procedure.
The manual release (3) may require adjustment after
replacing the operator assembly (15), magnet (15A), or
armature plate assembly (15E). It also may be required if
adjustments are made on the pivot stud nuts (19).
The release is working properly if:
a) You turn release knob clockwise to stop and the
brake is released;
b) The release knob returns to its normal position
automatically when power is applied to the magnet.
NOTE: Cover must be removed to make this adjustment.
1. To adjust: Set air gap “A” as described under “Wear
Adjustment” on page 5.
2. If the brake does not release, turn adjusting screw (5)
counterclockwise 1/4 turn and try again.
3. If the release knob (3) does not return to its normal
position automatically, turn screw (5) clockwise 1/4 turn
and try again.
NOTE: You may have to repeat Steps 2 or 3 to get
the release to operate properly.
It is important that the release knob returns to its
normal position automatically when power is applied
to the magnet.
Manual Release Assembly
Refer to Fig. 9.
1. Place a small amount of high temperature Neverseize
grease around o-ring (24) located on release knob (3) and
in release hole located at the top of bracket (2).
2. Place shaft of release knob (3) through hole in bracket
(2). Slide return spring (4) over shaft; straight leg of
spring should enter shaft first with leg in the position
shown.
3. Slip spring (6) over screw (5) and install in tapped hole
in release shaft. Screw in until it stops. Make sure spring
(4) is not caught under spring (6).
4. Engage bent end of spring (4) over spring (6) as shown.
Pull it over with a needle nose pliers or screwdriver.
5. Adjust release per “Manual Release Adjustment” section.

VERTICAL MOUNTING
Installation and adjustment of the vertically mounted brake is
the same as on the standard model.
Friction Disc Replacement
When replacing friction discs, follow procedure outlined
on page 6, with this addition:
Care must be taken to insure proper insertion of disc
separating springs. Springs are color coded for easy
identification, and reference is made to spring color (see
Figs. 10 and 11). Since the installation order of the disc
springs is dependent on brake mounting position (above
or below motor), it is important to consult the correct
diagram for spring location.

WARNING:
Brake performance and features must be carefully matched
to the requirements of the application.
Consideration must be given to torque requirements,
especially where an overhauling condition exists, as well
as thermal capacity, ambient temperature, atmospheric
explosion hazards, type of enclosure and any other unusu-
al conditions.
Improper selection and installation of a brake and/or lack
of maintenance may cause brake failure that could result in
damage to property and/or injury to personnel.
If injury to personnel could be caused by brake failure,
additional means must be provided to insure safety of
personnel.
GENERAL SAFETY INFORMATION
NOTE: These brakes are not intended for accurate positioning
applications. They are designed for applications that require
rapid stopping and holding power, such as on conveyors, door
openers, etc.
1. For applications with high inertia-type loads or rapid
cycling, the thermal capacity of the brake must be
considered.
2. Observe all local electrical and safety codes, as well as
the National Electrical Code (NEC) and the Occupational
Safety and Health Act (OSHA).
3. Brake motors and brake gearmotors must be securely and
adequately grounded. This can be accomplished by wiring
with a grounded metal-clad raceway system, by using a
separate ground wire connected to the bare metal of the
motor frame, or other suitable means. Refer to NEC Article
250 (Grounding) for additional information. All wiring
should be done by a qualified electrician.
4. Always disconnect power before working on or near a brake
motor, a brake gearmotor, or its connected load. If the
power disconnect point is out of sight, lock it in the open
position and tag it to prevent unexpected application of
power.
5. When working on the brake, be sure the load is completely
removed, secured or blocked to prevent injury or property
damage.
6. Provide guarding for all moving parts.
7. Be careful when touching the exterior of an operating
motor, gearmotor or brake. It may be hot enough to cause
injury or to be painful. This condition is normal for modern
motors, which operate at higher temperatures when running
at rated load and voltage.
8. Protect all electrical lead wires and power cables against
contact with sharp objects or moving parts.
9. Do not kink electrical lead wires and power cables, and
never allow them to touch oil, grease, hot surfaces or
chemicals.
