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)
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.
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)
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)
