Introduction

Performance Plus versions of Warner Electric
Unimodules are completely assembled
clutch/brake packages for out of box use. They
are engineered for easy installation, while pro­viding extra long life over standard units.
Technically advanced ceramic friction material
provides exceptional wear resistance and
enhanced performance making Performance
Plus Unimodule clutch/brakes ideal for high
cycle rate applications.

Performance Plus clutch/brake combinations are
offered in two configurations. The "1020" has a
hub input and a male shaft output. The "2030"
has a male shaft extension for both input and
output. These two configurations are offered
with various mounting accessories to make
ceramic friction faced Performance Plus
Unimodules adaptable to many power transmis­sion systems.

This manual covers installation, wiring and trou­bleshooting of the ceramic faced models which
are offered in clutch/brake sizes 50, 180 and

210.

Follow the installation instructions in this manual
carefully to ensure safe, reliable operation. All
stated or implied manufacturer warranties are
voided if this product is not installed in accor­dance with these instructions.

Make sure all power is turned
off to this equipment when installing, as
injury (or even death) may result from con­tact with live wires or rotating shafts.

Installation

Note: Before installing the unimodule to a motor

or reducer, make certain that the UM size and
NEMA frame dimensions match according to
Table 1 below.

Note: The equipment covered by this service
manual must be installed in accordance with
these instructions. Failure to do so may damage
the equipment and void the warranty.

Mounting to a Motor

Step 1

Note: The 1020 Unimodule is furnished with a
special hardened key. It is strongly recommend­ed that this key be used with the motor shaft to
avoid damage to the shaft and rotor hub.

Note: Size 210 Unimodules require an adapter
ring to be mounted to the motor prior to mount­ing the 1020 Unimodule. Adapter and mounting
hardware are provided with each Unimodule
assembly.

Note: Before mounting, check the motor shaft
for endplay. If the shaft can be moved axially
.030" or more, excessive thrust may occur
between the rotor and field. The
motor should be replaced unless the endplay
can be reduced.

Note: If the optional fan accessory is being
used, it should be installed prior to mounting the
Unimodule to a motor or reducer. Follow the
instructions provided with the fan
accessory.

Replace the existing motor shaft key with the
hardened key provided with the unit. If neces­sary, prick punch the keyway of the motor shaft
to keep the key from moving in the keyway.
Slide the module assembly onto the motor shaft.
(See Figure 1) Align the key in the motor shaft
with the keyway in the rotor hub.

Do not use force. If the UniModule does
not slide on freely, polish the motor shaft
sufficiently to achieve a slip fit.

Step 2

The housing is provided with vent holes which
are normally placed in the down position. Rotate
the assembly to where the vent holes are toward
the bottom and insert the four long capscrews
(provided) through the mounting holes in the
housing and into the motor face. Tighten alter­nately and securely. (30 to 35 ft. lbs.)

Figure 2

Step 3

The access hole for the Allen wrench to tighten
the rotor setscrews is shown in Figure 3. Rotate
the clutch rotor as necessary to insert the
wrench into the setscrews. Tighten both screws
alternately and securely. (40 to 45 in. lbs. for 180
size, 80 to 85 in. lbs. for 50 and 210 sizes.)
