The motor brakes will mount on a NEMA "C"
face motors frame size 213C, 215C, 254UC
and 256UC.
A. Mounting the Adapter and Magnet
1. Mount the adapter to the C-flange end bell
of the motor. Secure the adapter with
capscrews and lockwashers.
2. Mount the magnet to the adapter with
capscrews and lockwashers. Be sure both
surfaces are clean and free of burrs and
chips. A machined pilot diameter on the O.D.
of the magnet mounting flange corresponds
with a pilot diameter on the adapter.
B. Assembling the Armature and Hub
Assemble the armature to the armature hub
with the autogap mounting accessory.
Follow these instructions to assemble the
armature and hub:
Step 1
Insert the drive pin into the hub and tighten until
the shoulder of the pin is against the hub.
(See Figure 1.)
Step 2
Assemble the red spring over the drive pin. The
smaller diameter of the spring should be against
the hub (Figure 1).
Step 3
Place the detent retainer over the pin. The
cupped-out portion should be against the spring.
(See Figure 2.)
Step 4
Place the detent ring on the pin and press it into
the recessed portion of the detent retainer (Figure
2).
Step 5
Slide the detent ring towards the hub to allow
about 1/2" between the ring and the head of the
pin (Figure 2).
Step 6
Slide the armature onto the pins. The face of the
armature should be towards the hub. (Figure 3)
